185-716: Electrical telegraphy is a point-to-point text messaging system, primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs , that were devised to send text messages more quickly than physically carrying them. Electrical telegraphy can be considered the first example of electrical engineering . Text telegraphy consisted of two or more geographically separated stations, called telegraph offices . The offices were connected by wires, usually supported overhead on utility poles . Many electrical telegraph systems were invented that operated in different ways, but
370-741: A cellular network or may also be sent via satellite or Internet connection. The term originally referred to messages sent using the Short Message Service (SMS) on mobile devices. It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) and Rich Communication Services (RCS), which can contain digital images, videos, and sound content, as well as ideograms known as emoji ( happy faces , sad faces, and other icons), and on various instant messaging apps. Text messaging has been an extremely popular medium of communication since
555-451: A "two-fluid" theory of electricity. In the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning

Historically, this language developed out of shorthand used in bulletin board systems and later in Internet chat rooms , where users would abbreviate some words to allow a response to be typed more quickly, though the amount of time saved was often inconsequential. However, this became much more pronounced in SMS, where mobile phone users either have
925-570: A 1,000-foot range picocell, but it survived. American Personal Communications (APC), the first GSM carrier in America, provided the first text-messaging service in the United States. Sprint Telecommunications Venture, a partnership of Sprint Corp. and three large cable-TV companies, owned 49 percent of APC. The Sprint venture was the largest single buyer at a government-run spectrum auction that raised $ 7.7 billion in 2005 for PCS licenses. APC operated under

1295-585: A GSM subgroup under the leadership of Finn Trosby. It was further developed under the leadership of Kevin Holley and Ian Harris (see Short Message Service ). SMS forms an integral part of Signalling System No. 7 (SS7). Under SS7, it is a "state" with 160 characters of data, coded in the ITU-T "T.56" text format, that has a "sequence lead in" to determine different language codes and may have special character codes that permit, for example, sending simple graphs as text. This

Long before any knowledge of electricity existed, people were aware of shocks from electric fish . Ancient Egyptian texts dating from 2750 BCE referred to these fish as the "Thunderer of the Nile ", and described them as the "protectors" of all other fish. Electric fish were again reported millennia later by ancient Greek , Roman and Arabic naturalists and physicians . Several ancient writers, such as Pliny
1665-476: A character onscreen. Messages usually cost 0.05 to 0.86 Euro apiece, and games can require the player to send dozens of messages. In December 2003, a Finnish TV channel, MTV3 , put a Santa Claus character on-air reading aloud text messages sent in by viewers. On 12 March 2004, the first entirely "interactive" TV channel, VIISI, began operation in Finland. However, SBS Finland Oy took over the channel and turned it into

A survey conducted by MetrixLabs showed that 63% of Baby Boomers, 63% of Generation X, and 67% of Generation Y said that they used instant messengers in place of texting. A Facebook survey showed that 65% of people surveyed thought that messaging applications made group messaging easier. Of many texting trends, a system known as microblogging has surfaced, which consists of
2405-663: A distribution standard for outdoor and indoor lighting (eventually replacing direct current for such purposes). In the US there was a rivalry, primarily between a Westinghouse AC and the Edison DC system known as the " war of the currents ". "By the mid-1890s the four "Maxwell equations" were recognized as the foundation of one of the strongest and most successful theories in all of physics; they had taken their place as companions, even rivals, to Newton's laws of mechanics. The equations were by then also being put to practical use, most dramatically in
2590-468: A few kilometers (in von Sömmering's design), with each of the telegraph receiver's wires immersed in a separate glass tube of acid. An electric current was sequentially applied by the sender through the various wires representing each letter of a message; at the recipient's end, the currents electrolysed the acid in the tubes in sequence, releasing streams of hydrogen bubbles next to each associated letter or numeral. The telegraph receiver's operator would watch

For most people, half of their texts go to 3 – 5 other people. Research by Rosen et al. (2009) found that those young adults who used more language-based textisms (shortcuts such as LOL, 2nite, etc.) in daily writing produced worse formal writing than those young adults who used fewer linguistic textisms in daily writing. However,
3330-1288: A high quality of their services. Just one of many SMS applications that have proven highly popular and successful in the financial services industry is mobile receipts. In January 2009, Mobile Marketing Association (MMA) published the Mobile Banking Overview for financial institutions in which it discussed the advantages and disadvantages of mobile channel platforms such as Short Message Services (SMS), Mobile Web, Mobile Client Applications, SMS with Mobile Web and Secure SMS. Mobile interaction services are an alternative way of using SMS in business communications with greater certainty. Typical business-to-business applications are telematics and Machine-to-Machine , in which two applications automatically communicate with each other. Incident alerts are also common, and staff communications are also another use for B2B scenarios. Businesses can use SMS for time-critical alerts, updates, and reminders, mobile campaigns, content and entertainment applications. Mobile interaction can also be used for consumer-to-business interactions, such as media voting and competitions, and consumer-to-consumer interaction, for example, with mobile social networking, chatting and dating. Text messaging
3515-831: A large number of consumers racking up huge phone bills. A new type of free-premium or hybrid-premium content has emerged with the launch of text-service websites. These sites allow registered users to receive free text messages when items they are interested in go on sale, or when new items are introduced. An alternative to inbound SMS is based on long numbers (international mobile number format, e.g., +44 7624 805000, or geographic numbers that can handle voice and SMS, e.g., 01133203040 ), which can be used in place of short codes or premium-rated short messages for SMS reception in several applications, such as TV voting , product promotions and campaigns. Long numbers are internationally available, as well as enabling businesses to have their own number, rather than short codes, which are usually shared across
3700-445: A lot of brands. Additionally, long numbers are non-premium inbound numbers. The use of text messaging for workplace purposes grew significantly during the mid-2000s. As companies seek competitive advantages, many employees used new technology, collaborative applications, and real-time messaging such as SMS, instant messaging , and mobile communications to connect with teammates and customers. Some practical uses of text messaging include
3885-521: A miniaturized blog, inspired mainly by people's tendency to jot down informal thoughts and post them online. They consist of websites like X (formerly Twitter ) and its Chinese equivalent Weibo (微博). As of 2016, 21% of all American adults used Twitter. As of 2017, Weibo had 340 million active users. In some countries, text messages can be used to contact emergency services. In the UK, text messages can be used to call emergency services only after registering with

#17328519580214070-509: A month for €10. In Finland, which has very high mobile phone ownership rates, some TV channels began "SMS chat", which involved sending short messages to a phone number, and the messages would be shown on TV. Chats are always moderated, which prevents users from sending offensive material to the channel. The craze evolved into quizzes and strategy games and then faster-paced games designed for television and SMS control. Games require users to register their nicknames and send short messages to control
4255-508: A more efficient way to communicate. Crystal has also been quoted in saying that "In a logical world, text messaging should not have survived." But text messaging didn't just come out of nowhere. It originally began as a messaging system that would send out emergency information. But it gained immediate popularity with the public. What followed is the SMS we see today, which is a very quick and efficient way of sharing information from person to person. Work by Richard Ling has shown that texting has
4440-671: A moving paper tape by a stylus which was operated by an electromagnet. Morse and Vail developed the Morse code signalling alphabet . On May 24, 1844, Morse sent to Vail the historic first message “ WHAT HATH GOD WROUGHT " from the Capitol in Washington to the old Mt. Clare Depot in Baltimore . The first commercial electrical telegraph was the Cooke and Wheatstone system . A demonstration four-needle system
4625-515: A music channel named The Voice in November 2004. In 2006, the Prime Minister of Finland , Matti Vanhanen , made the news when he allegedly broke up with his girlfriend with a text message. In 2007, the first book written solely in text messages, Viimeiset viestit ( Last Messages ), was released by Finnish author Hannu Luntiala . It is about an executive who travels through Europe and India. In
4810-748: A number of spelling abbreviations: as in the phrase "txt msg", "u" (an abbreviation for "you"), "HMU"("hit me up"; i.e., call me), or use of camel case , such as in "ThisIsVeryLame". To avoid the even more limited message lengths allowed when using Cyrillic or Greek letters, speakers of languages written in those alphabets often use the Latin alphabet for their own language . In certain languages utilizing diacritic marks, such as Polish, SMS technology created an entire new variant of written language: characters normally written with diacritic marks (e.g., ą , ę , ś , ż in Polish) are now being written without them (as

In Mandarin Chinese , numbers that sound similar to words are used in place of those words. For example, the numbers 520 in Chinese ( wǔ èr líng ) sound like the words for "I love you" ( wǒ ài nǐ ). The sequence 748 ( qī sì bā ) sounds like
5180-573: A part of the voting system (there was also a voting over traditional landline phone lines). In 2005, the Eurovision Song Contest organized the biggest televoting ever (with SMS and phone voting). During roaming , (that is, when a user connects to another network in different country from their own) the prices may be higher, but in July 2009, EU legislation went into effect limiting this price to €0.11. Mobile service providers in Finland offered contracts in which users can send 1000 text messages
5365-426: A practical alphabetical system in 1840 called the A.B.C. System, used mostly on private wires. This consisted of a "communicator" at the sending end and an "indicator" at the receiving end. The communicator consisted of a circular dial with a pointer and the 26 letters of the alphabet (and four punctuation marks) around its circumference. Against each letter was a key that could be pressed. A transmission would begin with
5550-560: A primary role in the implication of former Detroit Mayor Kwame Kilpatrick in an SMS sex scandal. Short messages are particularly popular among young urbanites. In many markets, the service is comparatively cheap. For example, in Australia, a message typically costs between A$ 0.20 and $ 0.25 to send (some prepaid services charge $ 0.01 between their own phones), compared with a voice call, which costs somewhere between $ 0.40 and $ 2.00 per minute (commonly charged in half-minute blocks). The service
5735-436: A quick and easy way to communicate with friends, family, and colleagues, including in contexts where a call would be impolite or inappropriate (e.g., calling very late at night or when one knows the other person is busy with family or work activities). Like e-mail and voicemail , and unlike calls (in which the caller hopes to speak directly with the recipient), texting does not require the caller and recipient to both be free at

5920-544: A sensitive indicator for an electric current. Also that year, André-Marie Ampère suggested that telegraphy could be achieved by placing small magnets under the ends of a set of wires, one pair of wires for each letter of the alphabet. He was apparently unaware of Schweigger's invention at the time, which would have made his system much more sensitive. In 1825, Peter Barlow tried Ampère's idea but only got it to work over 200 feet (61 m) and declared it impractical. In 1830 William Ritchie improved on Ampère's design by placing
6105-493: A short amount of time and without needing to set time aside to engage in conversation. With voice calling, both participants need to be free at the same time. Mobile phone users can maintain communication during situations in which a voice call is impractical, impossible, or unacceptable, such as during a school class or work meeting. Texting has provided a venue for participatory culture , allowing viewers to vote in online and TV polls, as well as receive information while they are on
6290-404: A steady rhythm, and the usual speed of operation was 30 words per minute. By this point, reception had been automated, but the speed and accuracy of the transmission were still limited to the skill of the human operator. The first practical automated system was patented by Charles Wheatstone. The message (in Morse code ) was typed onto a piece of perforated tape using a keyboard-like device called
6475-464: A sufficient extent that the term texting (used as a verb meaning the act of mobile phone users sending short messages back and forth) has entered the common lexicon. In 2012, young Asians considered SMS as the most popular mobile phone application. In the same year, 50 percent of American teens send 50 text messages or more per day, making it their most frequent form of communication. In 2004 in China, SMS
6660-467: A telegraph along the Nuremberg–Fürth railway line , built in 1835 as the first German railroad, which was the first earth-return telegraph put into service. By 1837, William Fothergill Cooke and Charles Wheatstone had co-developed a telegraph system which used a number of needles on a board that could be moved to point to letters of the alphabet. Any number of needles could be used, depending on
6845-591: A typewriter at home, Hillebrand typed out random sentences and counted every letter, number, punctuation mark, and space. Almost every time, the messages contained fewer than 160 characters, thus giving the basis for the limit one could type via text messaging. With Bernard Ghillebaert of France Télécom , he developed a proposal for the GSM (Groupe Spécial Mobile) meeting in February 1985 in Oslo. The first technical solution evolved in
7030-475: A useful communication system. In 1774, Georges-Louis Le Sage realised an early electric telegraph. The telegraph had a separate wire for each of the 26 letters of the alphabet and its range was only between two rooms of his home. In 1800, Alessandro Volta invented the voltaic pile , providing a continuous current of electricity for experimentation. This became a source of a low-voltage current that could be used to produce more distinct effects, and which
7215-450: Is 1 peso per SMS (about US$ 0.023). Even after users were charged for SMS, it remained cheap, about one-tenth of the price of a voice call. This low price led to about five million Filipinos owning a cell phone by 2001. Because of the highly social nature of Philippine culture and the affordability of SMS compared to voice calls, SMS usage shot up. Filipinos used texting not only for social messages but also for political purposes, as it allowed
7400-550: Is available on a wide range of networks, including 3G networks. However, not all text-messaging systems use SMS; some notable alternate implementations of the concept include J-Phone 's SkyMail and NTT Docomo 's Short Mail , both in Japan. E-mail messaging from phones, as popularized by NTT Docomo's i-mode and the RIM BlackBerry , also typically use standard mail protocols such as SMTP over TCP/IP . As of 2007 , text messaging

Example: dv6 = dove sei ("where are you") and French k7 = cassette ("cassette tape"). There is also the use of numeral sequences, substituting for several syllables of a word and creating whole phrases using numerals. For example, in French, a12c4 can be said as à un de ces quatres , "see you around" (literally: "to one of these four [days] "). An example of using symbols in texting and borrowing from English

At a typical length of only 190 bytes (including protocol overhead), more than 350 of these messages per minute can be transmitted at the same data rate as a usual voice call (9 kbit/s). There are also free SMS services available, which are often sponsored, that allow sending and receiving SMS from a PC connected to the Internet. Mobile service providers in New Zealand, such as One NZ and Spark New Zealand , provided up to 2000 SMS messages for NZ$ 10 per month. Users on these plans sent on average 1500 SMS messages every month. Text messaging became so popular that advertising agencies and advertisers jumped into

The age that a child receives their first cell phone has also decreased, making text messaging a popular way of communicating. The number of texts sent in the US has gone up over the years as the price has gone down to an average of $ 0.10 per text sent and received. To convince more customers to buy unlimited text messaging plans, some major cellphone providers have increased

It may simply be referred to as a "text" in North America, the United Kingdom, Australia, New Zealand, and the Philippines; an "SMS" in most of mainland Europe; or an "MMS" or "SMS" in the Middle East, Africa, and Asia. The sender of a text message is commonly referred to as a "texter". The electrical telegraph systems, developed in
8325-830: Is the use of @ . Whenever it is used in texting, its intended use is with the English pronunciation. Crystal gives the example of the Welsh use of @ in @F , pronounced ataf, meaning "to me". In character-based languages such as Chinese and Japanese, numbers are assigned syllables based on the shortened form of the pronunciation of the number, sometimes the English pronunciation of the number. In this way, numbers alone can be used to communicate whole passages, such as in Chinese, "8807701314520" ( bào bao nǐ qīng qing nǐ yīshēng yìshì wǒ ài nǐ ) can be literally translated as "Hug hug you, kiss you, whole life, whole life I love you." English influences worldwide texting in variation, but still in combination with
8510-498: Is used for tsunami warnings and in Europe, SMS is used to inform individuals of imminent disasters. Since the location of a handset is known, systems can alert everyone in an area that the events have made impossible to pass through e.g. an avalanche. A similar system, known as Emergency Alert , is used in Australia to notify the public of impending disasters through both SMS and landline phone calls. These messages can be sent based on either

The U.S. And Canadian civil service both adopted BlackBerry smartphones in the 2000s. Group texts involve more than two users. They are often used when it is helpful to message many people at once, such as inviting multiple people to an event or arranging groups. They are also used in business for marketing and other customer notifications as well as intracompany communication. Group texts are often sent as MMS messages and therefore require an internet connection to send instead of using

In 1998, Philippine mobile service providers launched SMS more widely across the country, with initial television marketing campaigns targeting hearing-impaired users. The service was initially free with subscriptions, but Filipinos quickly exploited the feature to communicate for free instead of using voice calls, which they would be charged for. After telephone companies realized this trend, they began charging for SMS. The rate across networks
12765-489: The Royal Society the same year. Hauksbee continued to experiment with electricity, making numerous observations and developing machines to generate and demonstrate various electrical phenomena. In 1709 he published Physico-Mechanical Experiments on Various Subjects which summarized much of his scientific work. Stephen Gray discovered the importance of insulators and conductors. C. F. du Fay seeing his work, developed
12950-444: The SMS traffic between businesses and mobile subscribers, being mainly responsible for carrying mission-critical messages, SMS for enterprises, content delivery and entertainment services involving SMS, e.g., TV voting. Considering SMS messaging performance and cost, as well as the level of text messaging services, SMS gateway providers can be classified as resellers of the text messaging capability of another provider's SMSC or offering
13135-496: The US agreed to stop billing for PSMS in 45 states, effectively ending its use in the United States. Outside the United States, premium short messages have been used for "real-world" services. For example, some vending machines now allow payment by sending a premium-rated short message, so that the cost of the item bought is added to the user's phone bill or subtracted from the user's prepaid credits. Recently, premium messaging companies have come under fire from consumer groups due to
13320-456: The United Kingdom, the figure was around 35–40 SMS messages per month. In each of these countries, the cost of sending an SMS message varied from €0.04–0.23, depending on the payment plan (with many contractual plans including all or several texts for free). In the United Kingdom, text messages are charged between £0.05–0.12. Curiously, France did not take to SMS in the same way, sending just under 20 messages on average per user per month. France has
13505-427: The United States in 2021, showing continued popularity of the technology. In the U.S., SMS is often charged both at the sender and at the destination, but, unlike phone calls, it cannot be rejected or dismissed. The reasons for lower uptake than other countries are varied. Many users have unlimited "mobile-to-mobile" minutes, high monthly minute allotments, or unlimited service. Moreover, " push to talk " services offer
13690-499: The United States, text messaging is very popular; as reported by CTIA in December 2009, the 286 million US subscribers sent 152.7 billion text messages per month, for an average of 534 messages per subscriber per month. The Pew Research Center found in May 2010 that 72% of U.S. adult cellphone users send and receive text messages. CTIA reported in 2022 that 2 trillion SMS and MMS were sent in
13875-549: The adult population had a mobile phone. In general, texting is more popular than making phone calls, as it is viewed as less intrusive and therefore more polite. In 2009, it was predicted that text messaging would become a key revenue driver for mobile network operators in Africa over the following couple of years. Today, text messaging is already slowly gaining influence in the African market. One such person used text messaging to spread
14060-527: The alphabet, a message could be transmitted by connecting the wire terminals in turn to an electrostatic machine, and observing the deflection of pith balls at the far end. The writer has never been positively identified, but the letter was signed C.M. and posted from Renfrew leading to a Charles Marshall of Renfrew being suggested. Telegraphs employing electrostatic attraction were the basis of early experiments in electrical telegraphy in Europe, but were abandoned as being impractical and were never developed into
14245-493: The amount is typically divided between the mobile network operator and the value added service provider (VASP), either through revenue share or a fixed transport fee. Services like 82ASK and Any Question Answered have used the PSMS model to enable rapid response to mobile consumers' questions, using on-call teams of experts and researchers. In November 2013, amidst complaints about unsolicited charges on bills, major mobile carriers in
14430-538: The application of electricity to communications at a distance. All the known effects of electricity – such as sparks , electrostatic attraction , chemical changes , electric shocks , and later electromagnetism – were applied to the problems of detecting controlled transmissions of electricity at various distances. In 1753, an anonymous writer in the Scots Magazine suggested an electrostatic telegraph. Using one wire for each letter of
14615-535: The armature was intended to make marks on paper tape, but operators learned to interpret the clicks and it was more efficient to write down the message directly. In 1851, a conference in Vienna of countries in the German-Austrian Telegraph Union (which included many central European countries) adopted the Morse telegraph as the system for international communications. The international Morse code adopted
14800-402: The ball to build up a charge, a glow was visible if he placed his hand on the outside of the ball. This glow was bright enough to read by. It seemed to be similar to St. Elmo's Fire . This effect later became the basis of the gas-discharge lamp , which led to neon lighting and mercury vapor lamps . In 1706 he produced an 'Influence machine' to generate this effect. He was elected a Fellow of
14985-418: The bar, creating a much more powerful electromagnet which could operate a telegraph through the high resistance of long telegraph wires. During his tenure at The Albany Academy from 1826 to 1832, Henry first demonstrated the theory of the 'magnetic telegraph' by ringing a bell through one-mile (1.6 km) of wire strung around the room in 1831. In 1835, Joseph Henry and Edward Davy independently invented
15170-473: The brand name Sprint Spectrum and launched its service on 15 November 1995, in Washington, D.C., and Baltimore, Maryland. Vice President Al Gore in Washington, D.C., made the initial phone call to launch the network, calling Mayor Kurt Schmoke in Baltimore. Initial growth of text messaging worldwide was slow, with customers in 1995 sending on average only 0,4 messages per GSM customer per month. One factor in
15355-402: The bubbles and could then record the transmitted message. This is in contrast to later telegraphs that used a single wire (with ground return). Hans Christian Ørsted discovered in 1820 that an electric current produces a magnetic field that will deflect a compass needle. In the same year Johann Schweigger invented the galvanometer , with a coil of wire around a compass, that could be used as
15540-684: The chemical and producing readable blue marks in Morse code. The speed of the printing telegraph was 16 and a half words per minute, but messages still required translation into English by live copyists. Chemical telegraphy came to an end in the US in 1851, when the Morse group defeated the Bain patent in the US District Court. For a brief period, starting with the New York–Boston line in 1848, some telegraph networks began to employ sound operators, who were trained to understand Morse code aurally. Gradually,
15725-481: The coil with the transmission wires by means of the commutator. The page of Gauss's laboratory notebook containing both his code and the first message transmitted, as well as a replica of the telegraph made in the 1850s under the instructions of Weber are kept in the faculty of physics at the University of Göttingen , in Germany. Gauss was convinced that this communication would be of help to his kingdom's towns. Later in
15910-444: The communicator. Pressing another key would then release the pointer and the previous key, and re-connect the magneto to the line. These machines were very robust and simple to operate, and they stayed in use in Britain until well into the 20th century. The Morse system uses a single wire between offices. At the sending station, an operator taps on a switch called a telegraph key , spelling out text messages in Morse code . Originally,
16095-623: The computing era. The arithmetic performance of these machines allowed engineers to develop completely new technologies and achieve new objectives, including the Apollo missions and the NASA Moon landing . In the mid-to-late 1950s, the term radio engineering gradually gave way to the name electronics engineering , which then became a stand-alone university degree subject, usually taught alongside electrical engineering with which it had become associated due to some similarities. The first working transistor
16280-517: The curse "go to hell" ( qù sǐ ba ). Predictive text software, which attempts to guess words ( Tegic 's T9 as well as iTap ) or letters (Eatoni's LetterWise ) reduces the labour of time-consuming input. This makes abbreviations not only less necessary but slower to type than regular words that are in the software's dictionary . However, it makes the messages longer, often requiring the text message to be sent in multiple parts and, therefore, costing more to send. The use of text messaging has changed
16465-464: The development of a practical incandescent lamp for indoor lighting, Thomas Edison switched on the world's first public electric supply utility in 1882, using what was considered a relatively safe 110 volts direct current system to supply customers. Engineering advances in the 1880s, including the invention of the transformer , led to electric utilities starting to adopting alternating current , up until then used primarily in arc lighting systems, as
16650-484: The development of domestic applications for electricity. Public interest led to exhibitions such featuring "homes of the future" and in the UK, the Electrical Association for Women was established with Caroline Haslett as its director in 1924 to encourage women to become involved in electrical engineering. The second world war saw tremendous advances in the field of electronics; especially in radar and with
16835-433: The device; M. O. Thurston, L. A. D’Asaro, and J. R. Ligenza who developed the diffusion processes, and H. K. Gummel and R. Lindner who characterized the device. This was a culmination of decades of field-effect research that began with Lilienfeld. The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses. It revolutionized the electronics industry , becoming
17020-414: The direction set by the commutator on the other end of the line. At first, Gauss and Weber used the telegraph to coordinate time, but soon they developed other signals and finally, their own alphabet. The alphabet was encoded in a binary code that was transmitted by positive or negative voltage pulses which were generated by means of moving an induction coil up and down over a permanent magnet and connecting
17205-450: The distinction), the operators may still internally transmit the content as short messages, especially if the destination is on the same network. Text messaging has historically been popular and cheap in China. About 700 billion messages were sent in 2007. Text message spam has also been a problem in China. In 2007, 353.8 billion spam messages were sent, up 93% from the previous year. It is about 12.44 messages per week per person. In 2010, it
17390-526: The early 19th century, used electrical signals to send text messages. In the late 19th century, wireless telegraphy was developed using radio waves . In 1933, the German Reichspost ( Reich postal service) introduced the first " telex " service. The University of Hawaii began using radio to send digital information as early as 1971, using ALOHAnet . Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom . Sitting at
17575-578: The east coast by 24 October 1861, bringing an end to the Pony Express . France was slow to adopt the electrical telegraph, because of the extensive optical telegraph system built during the Napoleonic era . There was also serious concern that an electrical telegraph could be quickly put out of action by enemy saboteurs, something that was much more difficult to do with optical telegraphs which had no exposed hardware between stations. The Foy-Breguet telegraph
17760-412: The electric current. The receiving instrument consisted of six galvanometers with magnetic needles, suspended from silk threads . The two stations of Schilling's telegraph were connected by eight wires; six were connected with the galvanometers, one served for the return current and one for a signal bell. When at the starting station the operator pressed a key, the corresponding pointer was deflected at
17945-601: The electric telegraph, visual systems were used, including beacons , smoke signals , flag semaphore , and optical telegraphs for visual signals to communicate over distances of land. An auditory predecessor was West African talking drums . In the 19th century, Yoruba drummers used talking drums to mimic human tonal language to communicate complex messages – usually regarding news of birth, ceremonies, and military conflict – over 4–5 mile distances. From early studies of electricity , electrical phenomena were known to travel with great speed, and many experimenters worked on
18130-445: The emergency SMS service. This service is primarily aimed at people who, because of disability, are unable to make a voice call. It has recently been promoted as a means for walkers and climbers to call emergency services from areas where a voice call is not possible due to low signal strength. In the US, there is a move to require both traditional operators and over-the-top messaging providers to support texting to 911. In Asia, SMS
18315-459: The emerging new technology of radio communications, but also in the telegraph, telephone, and electric power industries." By the end of the 19th century, figures in the progress of electrical engineering were beginning to emerge. Charles Proteus Steinmetz helped foster the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. During
18500-409: The event. Modern SMS text messaging is usually sent from one mobile phone to another. Finnish Radiolinja became the first network to offer a commercial person-to-person SMS text messaging service in 1994. When Radiolinja's domestic competitor, Telecom Finland (now part of TeliaSonera ), also launched SMS text messaging in 1995 and the two networks offered cross-network SMS functionality, Finland became
18685-526: The exact opposite was true for informal writing. This suggests that perhaps the act of using textisms to shorten communication words leads young adults to produce more informal writing, which may then help them to be better "informal" writers. Due to text messaging, teens are writing more, and some teachers see that this comfort with language can be harnessed to make better writers. This new form of communication may be encouraging students to put their thoughts and feelings into words and this may be able to be used as
18870-475: The first chair and the first faculty of electrical engineering worldwide. In the same year, under Professor Charles Cross, the Massachusetts Institute of Technology began offering the first option of Electrical Engineering within a physics department. In 1883, Darmstadt University of Technology and Cornell University introduced the world's first courses of study in electrical engineering and in 1885
19055-482: The first field effect transistors in which drain and source were adjacent at the same surface. They showed that silicon dioxide insulated, protected silicon wafers and prevented dopants from diffusing into the wafer. Following this research, Mohamed Atalla and Dawon Kahng proposed a silicon MOS transistor in 1959 and successfully demonstrated a working MOS device with their Bell Labs team in 1960. Their team included E. E. LaBate and E. I. Povilonis who fabricated
19240-515: The first means of radiowave telecommunication, which he began in 1894. In the early 20th century, manual operation of telegraph machines was slowly replaced by teleprinter networks. Increasing use of the telephone pushed telegraphy into only a few specialist uses; its use by the general public dwindled to greetings for special occasions. The rise of the Internet and email in the 1990s largely made dedicated telegraphy networks obsolete. Prior to
19425-540: The first nation where SMS text messaging was offered on a competitive as well as a commercial basis. GSM was allowed in the United States, but the radio frequencies were blocked and awarded to US "Carriers" to use US technology, which limited development of mobile messaging services in the US. The GSM in the US had to use a frequency allocated for private communication services (PCS) – what the ITU frequency régime had blocked for DECT ( Digital Enhanced Cordless Telecommunications ) –
19610-414: The first practical engineering application of electricity by William Fothergill Cooke and Charles Wheatstone who co-developed a telegraph system that used a number of needles on a board which were moved to point to letters of the alphabet. A five needle system was used initially, but was given up as too expensive. In 1838 an improvement reduced the number of needles to two, and a patent for this version
19795-629: The identity of lightning , and electricity from any other source, is to be attributed to the Arabs , who before the 15th century had the Arabic word for lightning ra‘ad ( رعد ) applied to the electric ray . Ancient cultures around the Mediterranean knew that certain objects, such as rods of amber , could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus , an ancient Greek philosopher, writing at around 600 BCE, described
19980-416: The individual properties of languages. American popular culture is also recognized in shorthand. For example, Homer Simpson translates into: ~(_8^(|). Crystal also suggests that texting has led to more creativity in the English language, giving people opportunities to create their own slang, emoticons , abbreviations, acronyms, etc. The feeling of individualism and freedom makes texting more popular and
20165-422: The instant connectivity of SMS and are typically unlimited. The integration between competing providers and technologies necessary for cross-network text messaging was not initially available. Some providers originally charged extra for texting, reducing its appeal. In the third quarter of 2006, at least 12 billion text messages were sent on AT&T's network, up almost 15% from the preceding quarter. While texting
20350-607: The invention of the magnetron by Randall and Boot at the University of Birmingham in 1940. Radio location , radio communication and radio guidance of aircraft were all developed at this time. An early electronic computing device, Colossus was built by Tommy Flowers of the GPO to decipher the coded messages of the German Lorenz cipher machine . Also developed at this time were advanced clandestine radio transmitters and receivers for use by secret agents. An American invention at
20535-453: The line communicate with neighbouring boxes by telegraphic sounding of single-stroke bells and three-position needle telegraph instruments. In the 1840s, the electrical telegraph superseded optical telegraph systems such as semaphores, becoming the standard way to send urgent messages. By the latter half of the century, most developed nations had commercial telegraph networks with local telegraph offices in most cities and towns, allowing
20720-451: The location of the phone or the address to which the handset is registered. In the early 2020s, device manufacturers have begun to integrate satellite messaging connectivity and satellite emergency services into conventional mobile phones for use in remote regions, where there is no reliable terrestrial cellular network. SMS messages are used in some countries as reminders of medical appointments. Missed outpatient clinic appointments cost
20905-490: The magnetic needles inside a coil of wire connected to each pair of conductors. He successfully demonstrated it, showing the feasibility of the electromagnetic telegraph, but only within a lecture hall. In 1825, William Sturgeon invented the electromagnet , with a single winding of uninsulated wire on a piece of varnished iron , which increased the magnetic force produced by electric current. Joseph Henry improved it in 1828 by placing several windings of insulated wire around
21090-411: The main screen without user interaction and is not automatically stored in the inbox. It can be useful in cases such as an emergency (e.g., fire alarm ) or confidentiality (e.g., one-time password ). SMS has historically been particularly popular in Europe, Asia (excluding Japan; see below), the United States, Australia, and New Zealand, while also gaining influence in Africa. Popularity has grown to
21275-469: The mercury dipping electrical relay , in which a magnetic needle is dipped into a pot of mercury when an electric current passes through the surrounding coil. In 1837, Davy invented the much more practical metallic make-and-break relay which became the relay of choice in telegraph systems and a key component for periodically renewing weak signals. Davy demonstrated his telegraph system in Regent's Park in 1837 and
21460-448: The most important guarantees industries such as financial services, energy and commodities trading, health care and enterprises demand in their mission-critical procedures. One way to guarantee such a quality of text messaging lies in introducing SLAs ( Service Level Agreement ), which are common in IT contracts. By providing measurable SLAs, corporations can define reliability parameters and set up
21645-435: The most widely used electronic device in the world. The MOSFET made it possible to build high-density integrated circuit chips. The earliest experimental MOS IC chip to be fabricated was built by Fred Heiman and Steven Hofstein at RCA Laboratories in 1962. MOS technology enabled Moore's law , the doubling of transistors on an IC chip every two years, predicted by Gordon Moore in 1965. Silicon-gate MOS technology
21830-432: The most widely used of its type was the Cooke and Wheatstone telegraph , invented in 1837. The second category are armature systems, in which the current activates a telegraph sounder that makes a click; communication on this type of system relies on sending clicks in coded rhythmic patterns. The archetype of this category was the Morse system and the code associated with it, both invented by Samuel Morse in 1838. In 1865,
22015-412: The move that allowed students of secondary schools to use mobile phone text language in the end-of-the-year-exam papers. Highly publicized reports, beginning in 2002, of the use of text language in school assignments, caused some to become concerned that the quality of written communication is on the decline, and other reports claim that teachers and professors are beginning to have a hard time controlling
22200-403: The move. Texting can also bring people together and create a sense of community through " Smart Mobs " or "Net War", which create "people power". Research in 2015 has also proven that text messaging is somehow making the social distances larger and could be ruining verbal communication skills for many people. The small phone keypad and the rapidity of typical text message exchanges have caused
22385-429: The muscles. Alessandro Volta 's battery, or voltaic pile , of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The first application of electricity that was put to practical use was electromagnetism . William Sturgeon invented the electromagnet in 1825. Electromagnets were then used in
22570-422: The number of characters it was required to code. In May 1837 they patented their system. The patent recommended five needles, which coded twenty of the alphabet's 26 letters. Samuel Morse independently developed and patented a recording electric telegraph in 1837. Morse's assistant Alfred Vail developed an instrument that was called the register for recording the received messages. It embossed dots and dashes on
22755-753: The number of missed psychiatric appointments by 25–28%, representing a potential national yearly saving of over £150 million. Because of the COVID-19 pandemic, medical facilities in the United States are using text messaging to coordinate the appointment process, including reminders, cancellations, and safe check-in. US-based cloud radiology information system vendor AbbaDox includes this in their patient engagement services. Short codes are special telephone numbers, shorter than full telephone numbers, that can be used to address SMS and MMS messages from mobile phones or fixed phones. There are two types of short codes: dialling and messaging. SMS gateway providers facilitate
22940-414: The ones that became widespread fit into two broad categories. First are the needle telegraphs, in which electric current sent down the telegraph line produces electromagnetic force to move a needle-shaped pointer into position over a printed list. Early needle telegraph models used multiple needles, thus requiring multiple wires to be installed between stations. The first commercial needle telegraph system and
23125-527: The physics professor Wilhelm Weber in Göttingen , installed a 1,200-metre-long (3,900 ft) wire above the town's roofs. Gauss combined the Poggendorff-Schweigger multiplicator with his magnetometer to build a more sensitive device, the galvanometer . To change the direction of the electric current, he constructed a commutator of his own. As a result, he was able to make the distant needle move in
23310-415: The pointer reached the position of the depressed key, it would stop and the magneto would be disconnected from the line. The communicator's pointer was geared to the magneto mechanism. The indicator's pointer was moved by a polarised electromagnet whose armature was coupled to it through an escapement . Thus the alternating line voltage moved the indicator's pointer on to the position of the depressed key on
23495-410: The pointers on the dials at both ends set to the start position. The transmitting operator would then press down the key corresponding to the letter to be transmitted. In the base of the communicator was a magneto actuated by a handle on the front. This would be turned to apply an alternating voltage to the line. Each half cycle of the current would advance the pointers at both ends by one position. When
23680-449: The price to send and receive text messages from $ .15 to $ .20 per message. This is over $ 1,300 per megabyte . Many providers offer unlimited plans, which can result in a lower rate per text, given sufficient volume. Japan was among the first countries to adopt short messages widely, with pioneering non-GSM services including J-Phone 's SkyMail and NTT Docomo 's Short Mail . Japanese adolescents first began text messaging, because it
23865-558: The printer decoded this tape to produce alphanumeric characters on plain paper. This was the origin of the Creed High Speed Automatic Printing System, which could run at an unprecedented 200 words per minute. His system was adopted by the Daily Mail for daily transmission of the newspaper contents. With the invention of the teletypewriter , telegraphic encoding became fully automated. Early teletypewriters used
24050-574: The problem. However, the notion that text language is widespread or harmful is refuted by research from linguistic experts. An article in The New Yorker explores how text messaging has anglicized some of the world's languages. The use of diacritic marks is dropped in languages such as French, as well as symbols in Ethiopian languages . In his book, Txtng: the Gr8 Db8 (which translates as "Texting:
24235-486: The project was cancelled following Schilling's death in 1837. Schilling was also one of the first to put into practice the idea of the binary system of signal transmission. His work was taken over and developed by Moritz von Jacobi who invented telegraph equipment that was used by Tsar Alexander III to connect the Imperial palace at Tsarskoye Selo and Kronstadt Naval Base . In 1833, Carl Friedrich Gauss , together with
24420-497: The public to send messages (called telegrams ) addressed to any person in the country, for a fee. Beginning in 1850, submarine telegraph cables allowed for the first rapid communication between people on different continents. The telegraph's nearly-instant transmission of messages across continents – and between continents – had widespread social and economic impacts. The electric telegraph led to Guglielmo Marconi 's invention of wireless telegraphy ,
24605-575: The quality of their relationships. They concluded this age group prefers "selective interpersonal relationships in which they maintain particular, partial, but rich relations, depending on the situation". The same studies showed participants rated friendships in which they communicated face-to-face and through text messaging as being more intimate than those in which they communicated solely face-to-face. This indicates participants make new relationships with face-to-face communication at an early stage, but use text messaging to increase their contact later on. As
24790-475: The receiving end. The system was very stable and accurate and became accepted around the world. The next improvement was the Baudot code of 1874. French engineer Émile Baudot patented a printing telegraph in which the signals were translated automatically into typographic characters. Each character was assigned a five-bit code, mechanically interpreted from the state of five on/off switches. Operators had to maintain
24975-414: The receiving station. Different positions of black and white flags on different disks gave combinations which corresponded to the letters or numbers. Pavel Schilling subsequently improved its apparatus by reducing the number of connecting wires from eight to two. On 21 October 1832, Schilling managed a short-distance transmission of signals between two telegraphs in different rooms of his apartment. In 1836,
25160-405: The relationships between participants grew more intimate, the frequency of text messaging also increased. However, short messaging has been largely rendered obsolete by the prevalence of mobile Internet e-mail, which can be sent to and received from any e-mail address, mobile or otherwise. That said, while usually presented to the user simply as a uniform "mail" service (and most users are unaware of
25345-479: The same GSM technology as other European countries, so the uptake is not hampered by technical restrictions. In the Republic of Ireland, in 2012, 1.5 billion messages were sent every quarter, on average 114 messages per person per month. In the United Kingdom, as of March 2012, over 1 billion text messages were sent every week. The Eurovision Song Contest organized the first pan-European SMS voting in 2002, as
25530-476: The same moment; this permits communication even between busy individuals. Text messages can also be used to interact with automated systems, for example, to order products or services from e-commerce websites or to participate in online contests. Advertisers and service providers use direct text marketing to send messages to mobile users about promotions, payment due dates, and other notifications instead of using postal mail , email , or voicemail . The service
25715-469: The same year, instead of a voltaic pile , Gauss used an induction pulse, enabling him to transmit seven letters a minute instead of two. The inventors and university did not have the funds to develop the telegraph on their own, but they received funding from Alexander von Humboldt . Carl August Steinheil in Munich was able to build a telegraph network within the city in 1835–1836. In 1838, Steinheil installed
25900-510: The sender's text messaging plan. There are a growing number of websites that allow users to send free SMS messages online. Some websites provide free SMS for promoting premium business packages. In 2003, Europe followed next behind Asia in terms of the popularity of the use of SMS. That year, an average of 16 billion messages were sent each month. Users in Spain sent a little more than fifty messages per month on average in 2003. In Italy, Germany and
26085-426: The sending rate. There were many experiments with moving pointers, and various electrical encodings. However, most systems were too complicated and unreliable. A successful expedient to reduce the cost per message was the development of telegraphese . The first system that did not require skilled technicians to operate was Charles Wheatstone's ABC system in 1840 in which the letters of the alphabet were arranged around
26270-464: The service by mobile phone subscribers occurs in the Philippines, with an average of 27 texts sent per day per subscriber. Text messaging is most often used between private mobile phone users, as a substitute for voice calls in situations where voice communication is impossible or undesirable (e.g., during a school class or a work meeting). Texting is also used to communicate very brief messages, such as informing someone that you will be late or reminding
26455-556: The slow take-up of SMS was that operators were slow to set up charging systems, especially for prepaid subscribers, and to eliminate billing fraud, which was possible by changing SMSC settings on individual handsets to use the SMSCs of other operators. Over time, this issue was eliminated by switch billing instead of billing at the SMSC and by new features within SMSCs that allowed the blocking of foreign mobile users sending messages through them. SMS
26640-457: The study of radio engineering at universities could only be undertaken as part of a physics degree. Later, in post war years, as consumer devices began to be developed, the field broadened to include modern TV, audio systems, Hi-Fi and latterly computers and microprocessors. In 1946 the ENIAC (Electronic Numerical Integrator and Computer) of John Presper Eckert and John Mauchly followed, beginning
26825-525: The text messaging business. Services that provide bulk text message sending are also becoming a popular way for clubs, associations, and advertisers to reach a group of opt-in subscribers quickly. In 2013, research suggested that Internet-based mobile messaging would grow to equal the popularity of SMS by the end of 2013, with nearly 10 trillion messages being sent through each technology. Services such as Facebook Messenger / WhatsApp , Signal (software) , Snapchat , Telegram (software) , Viber have led to
27010-678: The text messaging capability as an operator of their own SMSC with SS7 . SMS messaging gateway providers can provide gateway-to-mobile (Mobile Terminated–MT) services. Some suppliers can also supply mobile-to-gateway (text-in or Mobile Originated/MO services). Many operate text-in services on short codes or mobile number ranges, whereas others use lower-cost geographic text-in numbers. SMS has been widely used for delivering digital content, such as news alerts, financial information, pictures, GIFs, logos and ringtones. Such messages are also known as premium-rated short messages (PSMS). The subscribers are charged extra for receiving this premium content, and
27195-793: The time was a device to scramble the telephone calls between Winston Churchill and Franklin D. Roosevelt . This was called the Green Hornet system and worked by inserting noise into the signal. The noise was then extracted at the receiving end. This system was never broken by the Germans. A great amount of work was undertaken in the United States as part of the War Training Program in the areas of radio direction finding, pulsed linear networks, frequency modulation , vacuum tube circuits , transmission line theory and fundamentals of electromagnetic engineering . These studies were published shortly after
27380-406: The turn of the century and has also influenced changes in society. Text messages are used for personal, family, business, and social purposes. Governmental and non-governmental organizations use text messaging for communication between colleagues. In the 2010s, the sending of short informal messages became an accepted part of many cultures, as happened earlier with emailing . This makes texting
27565-430: The two clicks. The message was then written out in long-hand. Royal Earl House developed and patented a letter-printing telegraph system in 1846 which employed an alphabetic keyboard for the transmitter and automatically printed the letters on paper at the receiver, and followed this up with a steam-powered version in 1852. Advocates of printing telegraphy said it would eliminate Morse operators' errors. The House machine
27750-455: The use of SMS for confirming delivery or other tasks, for instant communication between a service provider and a client (e.g., a payment card company and a consumer), and for sending alerts. Several universities have implemented a system of texting students and faculties campus alerts. One such example is Penn State . As text messaging has proliferated in business, so too have regulations governing its use. One regulation specifically governing
27935-416: The use of sound operators eliminated the need for telegraph receivers to include register and tape. Instead, the receiving instrument was developed into a "sounder", an electromagnet that was energized by a current and attracted a small iron lever. When the sounding key was opened or closed, the sounder lever struck an anvil. The Morse operator distinguished a dot and a dash by the short or long interval between
28120-765: The use of text messaging in financial-services firms engaged in stocks, equities, and securities trading is Regulatory Notice 07-59, Supervision of Electronic Communications, December 2007 , issued to member firms by the Financial Industry Regulatory Authority (FINRA). In Regulatory Notice 07-59, FINRA noted that "electronic communications", "e-mail", and "electronic correspondence" may be used interchangeably and can include such forms of electronic messaging as instant messaging and text messaging. Industry has had to develop new technology to allow companies to archive their employees' text messages. Security, confidentiality, reliability, and speed of SMS are among
28305-520: The war in what became known as the 'Radio Communication Series' published by McGraw-Hill in 1946. In 1941 Konrad Zuse presented the Z3 , the world's first fully functional and programmable computer. Prior to the Second World War , the subject was commonly known as ' radio engineering ' and was primarily restricted to aspects of communications and radar, commercial radio and early television. At this time,
28490-434: The way that people talk and write essays, some believing it to be harmful. Children today are receiving cell phones at an age as young as eight years old; more than 35 per cent of children in second and third grade have their own mobile phones. Because of this, the texting language is integrated into the way that students think from an earlier age than ever before. In November 2006, New Zealand Qualifications Authority approved
28675-447: The word about HIV and AIDS. In September 2009, a multi-country campaign in Africa used text messaging to expose stock-outs of essential medicines at public health facilities and put pressure on governments to address the issue. The advent of text messaging made possible new forms of interaction that were not possible before. A person could carry out a conversation with another user without the constraint of being expected to reply within
28860-516: The world could be transformed by electricity. Over 50 years later, he joined the new Society of Telegraph Engineers (soon to be renamed the Institution of Electrical Engineers ) where he was regarded by other members as the first of their cohort. The donation of his extensive electrical library was a considerable boon for the fledgling Society. Development of the scientific basis for electrical engineering, using research techniques, intensified during
29045-530: Was a point-contact transistor invented by John Bardeen and Walter Houser Brattain while working under William Shockley at the Bell Telephone Laboratories (BTL) in 1947. They then invented the bipolar junction transistor in 1948. While early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, they opened the door for more compact devices. The first integrated circuits were
29230-405: Was a cheaper form of communication than the other available forms. Thus, Japanese theorists created the selective interpersonal relationship theory , claiming that mobile phones can change social networks among young people (classified as 13- to 30-year-olds). They theorized this age group had extensive but low-quality relationships with friends, and mobile phone usage may facilitate improvement in
29415-406: Was a five-needle, six-wire system, and had the major advantage of displaying the letter being sent so operators did not need to learn a code. The insulation failed on the underground cables between Paddington and West Drayton, and when the line was extended to Slough in 1843, the system was converted to a one-needle, two-wire configuration with uninsulated wires on poles. The cost of installing wires
29600-551: Was broken into two companies by regulation, with Chorus Ltd taking the landline infrastructure and Spark NZ providing services including over their mobile network. Vodafone NZ (now One NZ ) acquired mobile network provider Bellsouth New Zealand in 1998 and had 2.32 million customers as of July 2013. Vodafone launched the first Text messaging service in 1999 and has introduced innovative TXT services like SafeTXT and CallMe 2degrees Mobile Ltd launched in August 2009. In 2005, around 85% of
29785-519: Was considerably modified from the original American Morse code , and was based on a code used on Hamburg railways ( Gerke , 1848). A common code was a necessary step to allow direct telegraph connection between countries. With different codes, additional operators were required to translate and retransmit the message. In 1865, a conference in Paris adopted Gerke's code as the International Morse code and
29970-632: Was created in 1852 in Rochester, New York and eventually became the Western Union Telegraph Company . Although many countries had telegraph networks, there was no worldwide interconnection. Message by post was still the primary means of communication to countries outside Europe. Telegraphy was introduced in Central Asia during the 1870s. A continuing goal in telegraphy was to reduce the cost per message by reducing hand-work, or increasing
30155-525: Was developed by Federico Faggin at Fairchild in 1968. Since then, the MOSFET has been the basic building block of modern electronics. The mass-production of silicon MOSFETs and MOS integrated circuit chips, along with continuous MOSFET scaling miniaturization at an exponential pace (as predicted by Moore's law ), has since led to revolutionary changes in technology, economy, culture and thinking. The Apollo program which culminated in landing astronauts on
30340-513: Was eventually adopted. This was a two-needle system using two signal wires but displayed in a uniquely different way to other needle telegraphs. The needles made symbols similar to the Chappe optical system symbols, making it more familiar to the telegraph operators. The optical system was decommissioned starting in 1846, but not completely until 1855. In that year the Foy-Breguet system was replaced with
30525-664: Was far less limited than the momentary discharge of an electrostatic machine , which with Leyden jars were the only previously known human-made sources of electricity. Another very early experiment in electrical telegraphy was an "electrochemical telegraph" created by the German physician , anatomist and inventor Samuel Thomas von Sömmering in 1809, based on an earlier 1804 design by Spanish polymath and scientist Francisco Salva Campillo . Both their designs employed multiple wires (up to 35) to represent almost all Latin letters and numerals. Thus, messages could be conveyed electrically up to
30710-405: Was first investigated by Jagadish Chandra Bose during 1894–1896, when he reached an extremely high frequency of up to 60 GHz in his experiments. He also introduced the use of semiconductor junctions to detect radio waves, when he patented the radio crystal detector in 1901. John Fleming invented the first radio tube, the diode , in 1904. Reginald Fessenden recognized that
30895-426: Was granted a patent on 4 July 1838. Davy also invented a printing telegraph which used the electric current from the telegraph signal to mark a ribbon of calico infused with potassium iodide and calcium hypochlorite . The first working telegraph was built by the English inventor Francis Ronalds in 1816 and used static electricity. At the family home on Hammersmith Mall , he set up a complete subterranean system in
31080-452: Was henceforth the international standard. The US, however, continued to use American Morse code internally for some time, hence international messages required retransmission in both directions. In the United States, the Morse/Vail telegraph was quickly deployed in the two decades following the first demonstration in 1844. The overland telegraph connected the west coast of the continent to
31265-426: Was implemented in Germany during the 1930s as a network used to communicate within the government. At the rate of 45.45 (±0.5%) baud – considered speedy at the time – up to 25 telex channels could share a single long-distance telephone channel by using voice frequency telegraphy multiplexing , making telex the least expensive method of reliable long-distance communication. Automatic teleprinter exchange service
31450-452: Was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge, by coming up with the single fluid, two states theory of electricity. In 1791, Italian Luigi Galvani published his discovery of bioelectricity , demonstrating that electricity was the medium by which nerve cells passed signals to
31635-523: Was installed on the Euston to Camden Town section of Robert Stephenson 's London and Birmingham Railway in 1837 for signalling rope-hauling of locomotives. It was rejected in favour of pneumatic whistles. Cooke and Wheatstone had their first commercial success with a system installed on the Great Western Railway over the 13 miles (21 km) from Paddington station to West Drayton in 1838. This
31820-519: Was introduced into Canada by CPR Telegraphs and CN Telegraph in July 1957 and in 1958, Western Union started to build a Telex network in the United States. Text messaging Text messaging , or simply texting , is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile phones , tablet computers , smartwatches , desktops / laptops , or another type of compatible computer. Text messages may be sent over
32005-405: Was part of ISDN ( Integrated Services Digital Network ), and since GSM is based on this, it made its way to the mobile phone. Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone. The possibility of doing something is one thing; implementing it is another, but systems existed in 1988 that sent SMS messages to mobile phones (compare ND-NOTIS ). SMS messaging
32190-469: Was routine that the People's Republic of China government monitored text messages across the country for illegal content. Among Chinese migrant workers with little formal education, it is common to refer to SMS manuals when text messaging. These manuals are published as cheap, smaller-than-pocket-size booklets that offer diverse linguistic phrases to utilize as messages. SMS was introduced to selected markets in
32375-609: Was similar to modern atomic theory. His mentor, Leucippus, is credited with this same theory. The hypothesis of Leucippus and Democritus held everything to be composed of atoms . But these atoms , called "atomos", were indivisible, and indestructible. He presciently stated that between atoms lies empty space, and that atoms are constantly in motion. He was incorrect only in stating that atoms come in different sizes and shapes, and that each object had its own shaped and sized atom. An object found in Iraq in 1938, dated to about 250 BCE and called
32560-618: Was taken out by Cooke and Wheatstone. Cooke tested the invention, with the London & Blackwall Railway , the London & Birmingham Railway , and the Great Western Railway companies, successively allowing the use of their lines for the experiment. Subsequently, railways developed systems with signal boxes along the line communicating with their neighbouring boxes by telegraphic sounding of single-stroke bells and three-position needle telegraph instruments. Such systems implementing signalling block systems remained in use on rural lines well into
32745-452: Was the Intel 4004 , released in 1971. The Intel 4004 was designed and realized by Federico Faggin at Intel with his silicon-gate MOS technology, along with Intel's Marcian Hoff and Stanley Mazor and Busicom's Masatoshi Shima. This ignited the development of the personal computer. The 4004, a 4-bit processor, was followed in 1973 by the Intel 8080 , an 8-bit processor, which made possible
32930-529: Was the beginning of modern dynamos – that is, electrical generators which operate using a magnetic field. The invention of the industrial generator in 1866 by Werner von Siemens – which did not need external magnetic power – made a large series of other inventions possible. In 1873, James Clerk Maxwell published a unified treatment of electricity and magnetism in A Treatise on Electricity and Magnetism which stimulated several theorists to think in terms of fields described by Maxwell's equations . In 1878,
33115-466: Was the first published work on electric telegraphy and even described the risk of signal retardation due to induction. Elements of Ronalds' design were utilised in the subsequent commercialisation of the telegraph over 20 years later. The Schilling telegraph , invented by Baron Schilling von Canstatt in 1832, was an early needle telegraph . It had a transmitting device that consisted of a keyboard with 16 black-and-white keys. These served for switching
33300-469: Was the last great barrier to full automation. Large telegraphy providers began to develop systems that used telephone-like rotary dialling to connect teletypewriters. These resulting systems were called "Telex" (TELegraph EXchange). Telex machines first performed rotary-telephone-style pulse dialling for circuit switching , and then sent data by ITA2 . This "type A" Telex routing functionally automated message routing. The first wide-coverage Telex network
33485-523: Was the most widely used mobile data service, with 74% of all mobile phone users worldwide, or 2.4 billion out of 3.3 billion phone subscribers, being active users of the Short Message Service at the end of 2007. In countries such as Finland, Sweden, and Norway, over 85% of the population used SMS. The European average was about 80%, and North America was rapidly catching up, with over 60% active users of SMS by end of 2008 . The largest average usage of
33670-423: Was ultimately more economically significant than the cost of training operators. The one-needle telegraph proved highly successful on British railways, and 15,000 sets were in use at the end of the nineteenth century; some remained in service in the 1930s. The Electric Telegraph Company , the world's first public telegraphy company, was formed in 1845 by financier John Lewis Ricardo and Cooke. Wheatstone developed
33855-637: Was used for the first time on 3 December 1992, at the Three Tuns Public House in Reading, Berkshire, when Neil Papworth , a 22-year-old test engineer for Sema Group in the UK (now Airwide Solutions ), used a personal computer to send the text message " Merry Christmas " via the Vodafone network to the phone of Richard Jarvis, who was at a party in Newbury, Berkshire , which had been organized to celebrate
34040-523: Was used on four main American telegraph lines by 1852. The speed of the House machine was announced as 2600 words an hour. David Edward Hughes invented the printing telegraph in 1855; it used a keyboard of 26 keys for the alphabet and a spinning type wheel that determined the letter being transmitted by the length of time that had elapsed since the previous transmission. The system allowed for automatic recording on
34225-754: Was very popular and brought service providers significant profit (18 billion short messages were sent in 2001). It has been a very influential and powerful tool in the Philippines, where in 2008 the average user sent 10–12 text messages a day. The same year, the Philippines alone sent on average over 1 billion text messages a day, more than the annual average SMS volume of the countries in Europe, and even China and India. SMS saw hugely popular in India, where youngsters often exchanged many text messages, and companies provide alerts, infotainment, news, cricket scores updates, railway/airline booking, mobile billing, and banking services on SMS. Similarly, in 2008, text messaging played
