143-398: Paramount Global Content Distribution is the international television distribution arm of American media conglomerate , Paramount Global , originally established in 1962 as the international distribution division of Desilu Productions . With the sale of Desilu to Gulf+Western , then-owners of film studio Paramount Pictures , in 1968, the division evolved into Paramount's first foray into
286-458: A patent interference suit against Farnsworth. The U.S. Patent Office examiner disagreed in a 1935 decision, finding priority of invention for Farnsworth against Zworykin. Farnsworth claimed that Zworykin's 1923 system could not produce an electrical image of the type to challenge his patent. Zworykin received a patent in 1928 for a color transmission version of his 1923 patent application. He also divided his original application in 1931. Zworykin
429-473: A resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p , 1080i and 720p . Since 2010, with the invention of smart television , Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Prime Video , iPlayer and Hulu . In 2013, 79% of the world's households owned
572-600: A transistor -based UHF tuner . The first fully transistorized color television in the United States was the Quasar television introduced in 1967. These developments made watching color television a more flexible and convenient proposition. In 1972, sales of color sets finally surpassed sales of black-and-white sets. Color broadcasting in Europe was not standardized on the PAL format until
715-467: A tuner for receiving and decoding broadcast signals. A visual display device that lacks a tuner is correctly called a video monitor rather than a television. The television broadcasts are mainly a simplex broadcast meaning that the transmitter cannot receive and the receiver cannot transmit. The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. The first documented usage of
858-477: A 1925 demonstration, the image was dim, had low contrast and poor definition, and was stationary. Zworykin's imaging tube never got beyond the laboratory stage. However, RCA, which acquired the Westinghouse patent, asserted that the patent for Farnsworth's 1927 image dissector was written so broadly that it would exclude any other electronic imaging device. Thus, based on Zworykin's 1923 patent application, RCA filed
1001-403: A 2-inch-wide by 2.5-inch-high screen (5 by 6 cm). The large receiver had a screen 24 inches wide by 30 inches high (60 by 75 cm). Both sets could reproduce reasonably accurate, monochromatic, moving images. Along with the pictures, the sets received synchronized sound. The system transmitted images over two paths: first, a copper wire link from Washington to New York City, then
1144-512: A 33% stake in its joint-venture holding company, ElevenCo. Ten Network Holdings entered voluntary administration in June 2017 which ultimately led to CBS acquiring the entirety of the company that November. On 1 August 2012, Chellomedia revealed that the European versions of Zone Romantica , Zone Reality and Club would be rebranded respectively as CBS Drama , CBS Reality and CBS Action . Following
1287-573: A 90-episode syndication package. On 28 October that same year, CBS Broadcast International announced its acquisition of TV and ancillary market rights to four Academy Award/Oscar-winning films produced by Arthur Cohn such as Dangerous Moves , Black and White in Color , The Garden of the Finzi Continis and The Sky Above, The Mud Below . It also announced plans to pick up the bulletins of CBS Evening News with Dan Rather which would place it on
1430-402: A TV system with a 40-line resolution that employed a CRT display. This was the first working example of a fully electronic television receiver and Takayanagi's team later made improvements to this system parallel to other television developments. Takayanagi did not apply for a patent. In the 1930s, Allen B. DuMont made the first CRTs to last 1,000 hours of use, one of the factors that led to
1573-665: A camera tube, using the CRT instead as a flying-spot scanner to scan slides and film. Ardenne achieved his first transmission of television pictures on 24 December 1933, followed by test runs for a public television service in 1934. The world's first electronically scanned television service then started in Berlin in 1935, the Fernsehsender Paul Nipkow , culminating in the live broadcast of the 1936 Summer Olympic Games from Berlin to public places all over Germany. Philo Farnsworth gave
SECTION 10
#17328589329141716-609: A color television combining a traditional black-and-white display with a rotating colored disk. This device was very "deep" but was later improved with a mirror folding the light path into an entirely practical device resembling a large conventional console. However, Baird was unhappy with the design, and, as early as 1944, had commented to a British government committee that a fully electronic device would be better. In 1939, Hungarian engineer Peter Carl Goldmark introduced an electro-mechanical system while at CBS , which contained an Iconoscope sensor. The CBS field-sequential color system
1859-409: A communal viewing experience to a solitary viewing experience. By 1960, Sony had sold over 4 million portable television sets worldwide. The basic idea of using three monochrome images to produce a color image had been experimented with almost as soon as black-and-white televisions had first been built. Although he gave no practical details, among the earliest published proposals for television
2002-522: A dish of under 1.2 metres, which would require individual planning permission for each customer. Lazard Brothers , the Pearson subsidiary responsible for BSB's first fundraising memorandum, reportedly regarded Astra as technology-led rather than programming-led and, therefore, an unlikely threat. The stage was set for a dramatic confrontation: BSB, expecting to be the United Kingdom's only satellite service,
2145-786: A fellow of the Royal Society (UK), published a letter in the scientific journal Nature in which he described how "distant electric vision" could be achieved by using a cathode-ray tube, or Braun tube, as both a transmitting and receiving device, he expanded on his vision in a speech given in London in 1911 and reported in The Times and the Journal of the Röntgen Society. In a letter to Nature published in October 1926, Campbell-Swinton also announced
2288-464: A joint project to help cover the cost. Subsequently, the government allowed the IBA to bring in private companies to help cover the costs (dubbed as the "Club of 21"): Within a year, the consortium made it clear that the original launch date of 1986 would be delayed to 1989, while also asking the government to allow it to tender out the building of the new satellite system to help reduce cost. On 15 June 1985,
2431-509: A large marble-effect, glass-clad office building at 346 Queenstown Road, facing Battersea Park in the London Borough of Wandsworth . It was built in 1987–1988 and completed in 1989 by Peter Argyrou Associates at a cost of £26 million. The headquarters were vacated, leading to redundancy for most BSB staff with only a few moving to work at Sky Television 's studios in Isleworth . The building
2574-423: A lensed disk scanner with a 48-line resolution. He was granted U.S. Patent No. 1,544,156 (Transmitting Pictures over Wireless) on 30 June 1925 (filed 13 March 1922). Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on 7 April 1927. Their reflected-light television system included both small and large viewing screens. The small receiver had
2717-430: A licence to operate three channels. BSB forecast 400,000 homes would be equipped during its first year, but some doubts were cast as to whether this was possible. The Cable Authority welcomed the service, believing it would encourage more users, especially with its dedicated movie network. The original four satellite channels were: Around the time of the licence award, Amstrad withdrew its backing, as they believed it
2860-657: A line of the image. Although he never built a working model of the system, variations of Nipkow's spinning-disk " image rasterizer " became exceedingly common. Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on 24 August 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning
3003-515: A medium" dates from 1927. The term telly is more common in the UK. The slang term "the tube" or the "boob tube" derives from the bulky cathode-ray tube used on most TVs until the advent of flat-screen TVs . Another slang term for the TV is "idiot box." Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century. Alexander Bain introduced
SECTION 20
#17328589329143146-399: A microprocessor. Upgrade kits from companies such as Trac Satellite allowed re-tuning whilst other kits allowed fully working menu systems and decoding of 'soft' encrypted channels, although this required the receiver to have one of the later MAC chipsets. Some kits even included smart card readers and full D2-MAC decoding capability. Marco Polo House (originally stylised as "Marcopolo") was
3289-401: A new type of flat-plate satellite antenna called a " squarial " (i.e., "square aerial"). The illustrative model shown to the press was a dummy and BSB commissioned a working version under 45 cm (18") wide. A conventional dish of the same diameter was also available. The company had serious technical problems with the development of ITT 's D-MAC silicon chips needed for its MAC receivers. BSB
3432-500: A partnership that would exploit the rights to the Madison Square Garden properties. In 1995, Paramount International Television launched a joint venture to be headed by Peter Press. In 1998, James Dowaliby was tapped to be vice president of production and Christopher Ottinger was named vice president of business development at the division. Later that year, Paramount announced plans to enter international co-production. In 2000,
3575-442: A phosphor plate. The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-color image could be obtained. He also demonstrated the same system using monochrome signals to produce a 3D image (called " stereoscopic " at the time). A demonstration on 16 August 1944 was the first example of a practical color television system. Work on
3718-467: A production model was halted by the SCAP after World War II . Because only a limited number of holes could be made in the disks, and disks beyond a certain diameter became impractical, image resolution on mechanical television broadcasts was relatively low, ranging from about 30 lines up to 120 or so. Nevertheless, the image quality of 30-line transmissions steadily improved with technical advances, and by 1933
3861-455: A projection screen at London's Dominion Theatre . Mechanically scanned color television was also demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells , amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full-color image. The first practical hybrid system was again pioneered by John Logie Baird. In 1940 he publicly demonstrated
4004-591: A radio link from Whippany, New Jersey . Comparing the two transmission methods, viewers noted no difference in quality. Subjects of the telecast included Secretary of Commerce Herbert Hoover . A flying-spot scanner beam illuminated these subjects. The scanner that produced the beam had a 50-aperture disk. The disc revolved at a rate of 18 frames per second, capturing one frame about every 56 milliseconds . (Today's systems typically transmit 30 or 60 frames per second, or one frame every 33.3 or 16.7 milliseconds, respectively.) Television historian Albert Abramson underscored
4147-544: A report drawn up by John Jackson, by inviting the private-sector companies to apply for a new television franchise via satellite to provide a commercial service on the IBA's three DBS channels (of the five in total allocated to the United Kingdom). One of the conditions imposed on applicants by the IBA was that they use a new untried transmission standard, D-MAC . This was part of the European Communities ' support for
4290-592: A resolution that was not surpassed until May 1932 by RCA, with 120 lines. On 25 December 1926, Kenjiro Takayanagi demonstrated a television system with a 40-line resolution that employed a Nipkow disk scanner and CRT display at Hamamatsu Industrial High School in Japan. This prototype is still on display at the Takayanagi Memorial Museum in Shizuoka University , Hamamatsu Campus. His research in creating
4433-493: A royalty-sharing agreement for all television and set-top boxes sold. The IBA was not directed to be an "economic regulator", so the free market in lower power satellite bandwidth satellites (such as SES Astra ) leveraged the benefits of the existing lower cost PAL transmissions with pre-existing set-top box technology. The IBA was rendered helpless and Murdoch voluntarily agreed to adhere to those Broadcasting Standards Commission rules relating to non-economic matters, such as

4576-426: A safe disposal orbit in 2003 as it reached the normal end of its operational life when fuel ran out. Marcopolo 2 was operated (as Thor 1 ) until January 2002 and disposed of successfully. A new television transmission system, Multiplexed Analogue Components , was originally developed for high-definition television but European manufacturers developed patented variants and successfully lobbied regulators such that it
4719-625: A signal reportedly to the 60th power or better and showed great promise in all fields of electronics. Unfortunately, an issue with the multipactor was that it wore out at an unsatisfactory rate. At the Berlin Radio Show in August 1931 in Berlin , Manfred von Ardenne gave a public demonstration of a television system using a CRT for both transmission and reception, the first completely electronic television transmission. However, Ardenne had not developed
4862-410: A static photocell. The thallium sulfide (Thalofide) cell, developed by Theodore Case in the U.S., detected the light reflected from the subject and converted it into a proportional electrical signal. This was transmitted by AM radio waves to a receiver unit, where the video signal was applied to a neon light behind a second Nipkow disk rotating synchronized with the first. The brightness of the neon lamp
5005-459: A system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the " Braun tube" ( cathode-ray tube or "CRT") in the receiver. Moving images were not possible because, in the scanner: "the sensitivity was not enough and the selenium cell was very laggy". In 1921, Édouard Belin sent the first image via radio waves with his belinograph . By
5148-545: A tape-delayed basis on international channel Tele Monte Carlo . CBS Broadcast International launched a global programming alliance with Virgin Media Television in 1997. That following year, Stephanie Pacheco was named the managing director of international sales of the division. CBS Broadcast International and Paramount International Television merged on August 11, 2004 to create CBS Paramount International Television and would be headed by Armando Nuarez Jr. The division
5291-490: A television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED ), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s were still CRT , it was only in early 2010s that flat-screen TVs decisively overtook CRT. Major manufacturers announced
5434-484: A television system using fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube. The problem of low sensitivity to light resulting in low electrical output from transmitting or "camera" tubes would be solved with the introduction of charge-storage technology by Kálmán Tihanyi beginning in 1924. His solution was a camera tube that accumulated and stored electrical charges ("photoelectrons") within
5577-482: A variant, D-MAC , which had marginal audio channel improvements, and insisted on its use by the satellite service to be licensed by itself. In the rest of Europe, satellite television manufacturers standardised on another variant, D2-MAC , which used less bandwidth and was compatible with the extensive existing European cable systems. With the launch of BSB, the IBA became a member of the secret "MAC Club" of European organisations which owned patents on MAC variants and had
5720-442: Is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission . Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than " radio broadcasting ," which refers to an audio signal sent to radio receivers . Television became available in crude experimental forms in
5863-511: The 1939 New York World's Fair . On the other hand, in 1934, Zworykin shared some patent rights with the German licensee company Telefunken. The "image iconoscope" ("Superikonoskop" in Germany) was produced as a result of the collaboration. This tube is essentially identical to the super-Emitron. The production and commercialization of the super-Emitron and image iconoscope in Europe were not affected by

6006-471: The Astra system and broadcast in PAL with analogue sound. BSB had been aware of the impending launch of Astra when it submitted its proposal to the IBA in 1986 but had discounted it, partly on advice from the IBA that it would not have been possible for Sky to securely scramble an analogue PAL signal and a prediction that satisfactory reception from a medium-powered satellite such as Astra would not be possible with
6149-724: The EMI engineering team led by Isaac Shoenberg applied in 1932 for a patent for a new device they called "the Emitron", which formed the heart of the cameras they designed for the BBC. On 2 November 1936, a 405-line broadcasting service employing the Emitron began at studios in Alexandra Palace and transmitted from a specially built mast atop one of the Victorian building's towers. It alternated briefly with Baird's mechanical system in adjoining studios but
6292-603: The European Union regulations with potentially superior picture sharpness, digital stereo sound, and the potential to show widescreen programming; rather than the existing PAL system. BSB claimed that Sky's PAL pictures would be too degraded by satellite transmission, and that in any case, BSB would broadcast superior programming. SES (later operators of the O3b data satellites and others with names including AMC , Ciel , NSS , QuetzSat , YahSat and SES , and formerly at that time,
6435-474: The patent war between Zworykin and Farnsworth because Dieckmann and Hell had priority in Germany for the invention of the image dissector, having submitted a patent application for their Lichtelektrische Bildzerlegerröhre für Fernseher ( Photoelectric Image Dissector Tube for Television ) in Germany in 1925, two years before Farnsworth did the same in the United States. The image iconoscope (Superikonoskop) became
6578-404: The "Iconoscope" by Zworykin, the new tube had a light sensitivity of about 75,000 lux , and thus was claimed to be much more sensitive than Farnsworth's image dissector. However, Farnsworth had overcome his power issues with his Image Dissector through the invention of a completely unique " Multipactor " device that he began work on in 1930, and demonstrated in 1931. This small tube could amplify
6721-419: The 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II , an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion . In
6864-653: The 1920s, when amplification made television practical, Scottish inventor John Logie Baird employed the Nipkow disk in his prototype video systems. On 25 March 1925, Baird gave the first public demonstration of televised silhouette images in motion at Selfridges 's department store in London . Since human faces had inadequate contrast to show up on his primitive system, he televised a ventriloquist's dummy named "Stooky Bill," whose painted face had higher contrast, talking and moving. By 26 January 1926, he had demonstrated before members of
7007-421: The 1960s, and broadcasts did not start until 1967. By this point, many of the technical issues in the early sets had been worked out, and the spread of color sets in Europe was fairly rapid. By the mid-1970s, the only stations broadcasting in black-and-white were a few high-numbered UHF stations in small markets and a handful of low-power repeater stations in even smaller markets such as vacation spots. By 1979, even
7150-411: The 50:50 merged venture having an effective quasi-monopoly on British satellite pay-television. From a United Kingdom perspective, British Satellite Broadcasting's existence prevented 100% of these profits being made by News International, reducing Murdoch's ability to influence government policy. At one stage of the saga, News International was facing dismemberment at the hands of its bankers. Following
7293-504: The Astra TV satellite operator), had no regulatory permission to broadcast, had plans (initially) for only one satellite with no backup, and the European satellite launch vehicle Ariane suffered repeated failures. However, SES used the resulting delay time to re-engineer the satellite to reduce the dish size needed, which would otherwise have been larger than 60 cm (24"). To distance itself from Sky and its dish antennas, BSB announced

On February 16, 2022, ViacomCBS rebranded as Paramount Global , rebranding the division likewise to its current name and restoring the "Paramount" name in television for the first time in 17 years. ViacomCBS International Studios
7579-664: The Dutch company Philips produced and commercialized the image iconoscope and multicon from 1952 to 1958. U.S. television broadcasting, at the time, consisted of a variety of markets in a wide range of sizes, each competing for programming and dominance with separate technology until deals were made and standards agreed upon in 1941. RCA, for example, used only Iconoscopes in the New York area, but Farnsworth Image Dissectors in Philadelphia and San Francisco. In September 1939, RCA agreed to pay
7722-631: The Farnsworth Television and Radio Corporation royalties over the next ten years for access to Farnsworth's patents. With this historic agreement in place, RCA integrated much of what was best about the Farnsworth Technology into their systems. In 1941, the United States implemented 525-line television. Electrical engineer Benjamin Adler played a prominent role in the development of television. The world's first 625-line television standard
7865-453: The HD-MAC high-definition television standard which was being developed by Philips and other European companies. The technology was still at the laboratory stage and was incompatible with previous standards: HD-MAC transmissions could not be received by existing television sets which used PAL or SECAM standards. The condition to use a high-power (230 watt) satellite was dropped, and no winner
8008-675: The PAL system would give adequate picture quality, and that many viewers would be happy to watch Sky's more populist output as opposed to waiting for the promised quality programming pledged by BSB. Sky had launched its multichannel service from studios at an industrial estate in Isleworth , with a 10-year lease on SES transponders for an estimated £50 million without backup. BSB on the other hand, would operate from more expensive headquarters at Marco Polo House in Battersea , with construction and launch of its own satellites costing an estimated £200 million as

This is widely regarded as the world's first true public television demonstration, exhibiting light, shade, and detail. Baird's system used the Nipkow disk for both scanning the image and displaying it. A brightly illuminated subject was placed in front of a spinning Nipkow disk set with lenses that swept images across
8294-553: The Science Museum, South Kensington. In 1928, Baird's company (Baird Television Development Company/Cinema Television) broadcast the first transatlantic television signal between London and New York and the first shore-to-ship transmission. In 1929, he became involved in the first experimental mechanical television service in Germany. In November of the same year, Baird and Bernard Natan of Pathé established France's first television company, Télévision- Baird -Natan. In 1931, he made
8437-459: The Telechrome continued, and plans were made to introduce a three-gun version for full color. However, Baird's untimely death in 1946 ended the development of the Telechrome system. Similar concepts were common through the 1940s and 1950s, differing primarily in the way they re-combined the colors generated by the three guns. The Geer tube was similar to Baird's concept but used small pyramids with
8580-560: The UK broadcasts using the Baird system were remarkably clear. A few systems ranging into the 200-line region also went on the air. Two of these were the 180-line system that Compagnie des Compteurs (CDC) installed in Paris in 1935 and the 180-line system that Peck Television Corp. started in 1935 at station VE9AK in Montreal .

It commissioned the Hughes Aircraft Company to provide two high-powered satellites using launch vehicles from McDonnell Douglas (later United Launch Alliance ). Both companies were American and had established reputations for reliability. Hughes was the main contractor and offered a commercial space industry as the first "in-orbit delivery" on 6 August 1987. BSB's risk
9295-496: The company, along with MCA TV International , signed an agreement with China Central Television (CCTV), to offer a total of 100 drama hours. The deal, the largest license ever granted to Chinese television in that era, made the two Hollywood studios the largest suppliers of foreign production for that country. In 1990, it briefly considered an investment in Australia's Nine Network . In 1986, Paramount Television International formed
9438-462: The convenience of remote retrieval, the storage of television and video programming now also occurs on the cloud (such as the video-on-demand service by Netflix ). At the beginning of the 2010s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) ( 576i , with 576 interlaced lines of resolution and 480i ) to high-definition television (HDTV), which provides

The patent for his receiving tube had been granted the previous October. Both patents had been purchased by RCA prior to their approval. Charge storage remains a basic principle in the design of imaging devices for television to the present day. On 25 December 1926, at Hamamatsu Industrial High School in Japan, Japanese inventor Kenjiro Takayanagi demonstrated
9867-514: The development of HDTV technology, the MUSE analog format proposed by NHK , a Japanese company, was seen as a pacesetter that threatened to eclipse U.S. electronics companies' technologies. Until June 1990, the Japanese MUSE standard, based on an analog system, was the front-runner among the more than 23 other technical concepts under consideration. Then, a U.S. company, General Instrument, demonstrated
10010-535: The discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. LEDs are being gradually replaced by OLEDs. Also, major manufacturers have started increasingly producing smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s. Television signals were initially distributed only as terrestrial television using high-powered radio-frequency television transmitters to broadcast
10153-468: The dissemination of visual and textual television programs on a subscription/fee basis. Viacom International also served as the licensee name and division for its group of television stations for FCC purposes before the 1995 Westinghouse/CBS merger. Former Viacom station WVIT in New Britain, Connecticut (serving Hartford and New Haven ), which it owned from 1978 until 1997, took its call letters from

In 1981, CBS launched its international division, CBS Broadcast International , to sell news, sports and entertainment programming produced in-house to foreign markets as well as non-broadcast and new technology markets in the U.S. It eventually merged into CBS Worldwide Enterprises and later incorporated into its marketing unit CBS Productions (unrelated to
10725-421: The extra information in the signal and produce a limited-resolution color display. The higher-resolution black-and-white and lower-resolution color images combine in the brain to produce a seemingly high-resolution color image. The NTSC standard represented a significant technical achievement. The first color broadcast (the first episode of the live program The Marriage ) occurred on 8 July 1954. However, during
10868-468: The facsimile machine between 1843 and 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. Willoughby Smith discovered the photoconductivity of the element selenium in 1873. As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884 in Berlin . This was a spinning disk with a spiral pattern of holes, so each hole scanned
11011-440: The first outdoor remote broadcast of The Derby . In 1932, he demonstrated ultra-short wave television. Baird's mechanical system reached a peak of 240 lines of resolution on BBC telecasts in 1936, though the mechanical system did not scan the televised scene directly. Instead, a 17.5 mm film was shot, rapidly developed, and then scanned while the film was still wet. A U.S. inventor, Charles Francis Jenkins , also pioneered
11154-431: The following ten years, most network broadcasts and nearly all local programming continued to be black-and-white. It was not until the mid-1960s that color sets started selling in large numbers, due in part to the color transition of 1965, in which it was announced that over half of all network prime-time programming would be broadcast in color that fall. The first all-color prime-time season came just one year later. In 1972,
11297-506: The general public with a sixth part-time service on subscription for business users, as BSB Datavision was a subsidiary of the company which offered encrypted television sets and data reception through domestic receivers. BSB's channel line-up launched over five consecutive days in one at a time was: BSB launched its service on cable 25 March 1990 and on satellite at the end of April, with the slogan It's Smart to be Square . The launch, six months late, came 13 months after Sky 's launch. BSB
11440-479: The government imposed two conditions on it: During Autumn 1983, the cost of Unisat was found to be greatly underestimated and the new Home Secretary announced the three remaining channels would be given to the Independent Broadcasting Authority (IBA) to allow the private sector to compete against the BBC in satellite broadcasting. Within a few months, the BBC started talking with the IBA about
11583-417: The iconoscope (or Emitron) produced an electronic signal and concluded that its real efficiency was only about 5% of the theoretical maximum. They solved this problem by developing and patenting in 1934 two new camera tubes dubbed super-Emitron and CPS Emitron . The super-Emitron was between ten and fifteen times more sensitive than the original Emitron and iconoscope tubes, and, in some cases, this ratio
11726-618: The industrial standard for public broadcasting in Europe from 1936 until 1960, when it was replaced by the vidicon and plumbicon tubes. Indeed, it represented the European tradition in electronic tubes competing against the American tradition represented by the image orthicon. The German company Heimann produced the Superikonoskop for the 1936 Berlin Olympic Games, later Heimann also produced and commercialized it from 1940 to 1955; finally
11869-514: The initial £222.5 million. After unsuccessfully offering its stake in BSB to the remaining founders, Virgin sold it to the Bond Corporation , already BSB's largest shareholder for a nominal profit. Despite the delayed launch, BSB continued to invest heavily in marketing in 1989 to minimize the effects of Sky's timing advantage. BSB also received a needed boost in June 1989 when it won the franchises for
12012-418: The initials of Viacom International, and retains them to the present day under NBC ownership . In 2006, Viacom International was renamed to CBS Operations, Inc., and its copyrights related to Viacom's cable networks were transferred to a new Viacom International company. The new Viacom International remained an active company after Viacom and CBS merged to create ViacomCBS in 2019 and ViacomCBS rebranded as
12155-468: The international television industry in the 1970s. The division handles the distribution of television content from the libraries of Paramount Media Networks , Paramount Television Studios , CBS Studios , CBS Media Ventures , Showtime Networks and Paramount+ . The division as well as Paramount International Television was originally established in 1962 as the international distribution division of Desilu Productions , Desilu International , which
12298-437: The invention of the first working transistor at Bell Labs , Sony founder Masaru Ibuka predicted in 1952 that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets. The first fully transistorized, portable solid-state television set was the 8-inch Sony TV8-301 , developed in 1959 and released in 1960. This began the transformation of television viewership from
12441-401: The last holdout among daytime network programs converted to color, resulting in the first completely all-color network season. Early color sets were either floor-standing console models or tabletop versions nearly as bulky and heavy, so in practice they remained firmly anchored in one place. GE 's relatively compact and lightweight Porta-Color set was introduced in the spring of 1966. It used
12584-464: The last of these had converted to color. By the early 1980s, B&W sets had been pushed into niche markets, notably low-power uses, small portable sets, or for use as video monitor screens in lower-cost consumer equipment. By the late 1980s, even these last holdout niche B&W environments had inevitably shifted to color sets. Digital television (DTV) is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to
12727-482: The later company of the same name ) with CBS Theatrical Films in August 1984. In the summer of 1985, CBS Productions, CBS News and Columbia House partnered to produce a videocassette The Vietnam War with Walter Cronkite . Later that year, CBS shut down its theatrical production unit and CBS Broadcast International spun-out from the production unit, restoring the CBS Broadcast International moniker in
12870-557: The launch of RTL CBS Entertainment in September that year, but would be acquired 5 years later in January by Blue Ant Media. The division previously owned all CBS-branded European TV channels in a joint venture with AMC Networks International and an Australian television company, Ten Network Holdings . Both have since been transferred to the primary international networks division of Paramount Global. Television Television ( TV )
13013-939: The libraries of CBS Studios, the King World Productions and certain HBO shows internationally the Rysher Entertainment library, the latter owned domestically by 2929 Entertainment . In May 2009, CPITV was renamed CBS Studios International. On 14 September that year, CBS Studios International struck a joint venture deal with Chellomedia to launch six CBS-branded channels in the UK which would replace Zone Romantica , Zone Thriller , Zone Horror and Zone Reality , plus timeshift services Zone Horror +1 and Zone Reality +1. The replacement channels launched on 16 November that year. On 5 April 2010, Zone Horror and Zone Horror +1 were rebranded as Horror Channel and Horror Channel +1 respectively. CBS Studios International licensed rights for
13156-486: The mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The availability of various types of archival storage media such as Betamax and VHS tapes, LaserDiscs , high-capacity hard disk drives , CDs , DVDs , flash drives , high-definition HD DVDs and Blu-ray Discs , and cloud digital video recorders has enabled viewers to watch pre-recorded material—such as movies—at home on their own time schedule. For many reasons, especially
13299-466: The original Campbell-Swinton's selenium-coated plate. Although others had experimented with using a cathode-ray tube as a receiver, the concept of using one as a transmitter was novel. The first cathode-ray tube to use a hot cathode was developed by John B. Johnson (who gave his name to the term Johnson noise ) and Harry Weiner Weinhart of Western Electric , and became a commercial product in 1922. In 1926, Hungarian engineer Kálmán Tihanyi designed
13442-456: The phosphors deposited on their outside faces instead of Baird's 3D patterning on a flat surface. The Penetron used three layers of phosphor on top of each other and increased the power of the beam to reach the upper layers when drawing those colors. The Chromatron used a set of focusing wires to select the colored phosphors arranged in vertical stripes on the tube. One of the great technical challenges of introducing color broadcast television
13585-423: The planned £625 million it required to operate up to 1993. Virgin pulled out of the BSB consortium in December 1988, ostensibly because it was going private again and had become increasingly concerned about BSB's mounting costs. The film-rights battle proved to be the final straw for Virgin since it would necessitate a "supplementary first round" of financing of £131 million in January earlier that year in addition to
13728-452: The possibility of a digital television signal. This breakthrough was of such significance that the FCC was persuaded to delay its decision on an ATV standard until a digitally-based standard could be developed. British Satellite Broadcasting British Satellite Broadcasting plc (BSB) was a television company, based in London, that provided direct broadcast satellite television services to
13871-458: The process. It planned to provide the CBS Evening News bulletins to UK-based British Satellite Broadcasting in 1988. CBS Broadcast International produced syndicated episodes of the TV series, The Twilight Zone in 1985. It then signed a partnership agreement with MGM/UA Telecommunications 2 years later to syndicate its episodes from all 2 seasons with 30 new first-run episodes to form
14014-546: The project failed when consortium concluded that the cost of set-up was not justifiable. The BBC stated the costs were prohibitive because the government insisted that the "Club of 21" should pay for the costs of constructing and launching a dedicated satellite. On 2 April 1986, the IBA convinced the Home Secretary to revive the DBS project but under different conditions, broadly based on
14157-507: The public at this time, viewing of the color field tests was restricted to RCA and CBS engineers and the invited press. The War Production Board halted the manufacture of television and radio equipment for civilian use from 22 April 1942 to 20 August 1945, limiting any opportunity to introduce color television to the general public. As early as 1940, Baird had started work on a fully electronic system he called Telechrome . Early Telechrome devices used two electron guns aimed at either side of
14300-512: The receiver, a type of Kerr cell modulated the light, and a series of differently angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image was transmitted "several times" each second. In 1911, Boris Rosing and his student Vladimir Zworykin created
14443-415: The reproducer) marked the start of the end for mechanical systems as the dominant form of television. Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the 1930s. The last mechanical telecasts ended in 1939 at stations run by a lot of public universities in the United States. In 1897, English physicist J. J. Thomson
14586-561: The resolution of the color information to conserve bandwidth. As black-and-white televisions could receive the same transmission and display it in black-and-white, the color system adopted is [backwards] "compatible." ("Compatible Color," featured in RCA advertisements of the period, is mentioned in the song " America ," of West Side Story , 1957.) The brightness image remained compatible with existing black-and-white television sets at slightly reduced resolution. In contrast, color televisions could decode
14729-558: The results of some "not very successful experiments" he had conducted with G. M. Minchin and J. C. M. Stanton. They had attempted to generate an electrical signal by projecting an image onto a selenium-coated metal plate that was simultaneously scanned by a cathode ray beam. These experiments were conducted before March 1914, when Minchin died, but they were later repeated by two different teams in 1937, by H. Miller and J. W. Strange from EMI , and by H. Iams and A. Rose from RCA . Both teams successfully transmitted "very faint" images with
14872-653: The second of which was a backup. When BSB finally went on air in March 1990 (13 months after Sky), the company's technical problems were resolved and its programming was critically acclaimed. However, its D-MAC receivers were more expensive than Sky's PAL equivalents and incompatible with them. Many potential customers compared the competition between the rival satellite companies to the format war between VHS and Betamax recorders, and chose to wait and see which company would win outright in order to avoid buying potentially obsolete equipment. Both BSB and Sky had begun to struggle with
15015-449: The signal to individual television receivers. Alternatively, television signals are distributed by coaxial cable or optical fiber , satellite systems, and, since the 2000s, via the Internet. Until the early 2000s, these were transmitted as analog signals, but a transition to digital television was expected to be completed worldwide by the late 2010s. A standard television set consists of multiple internal electronic circuits , including
15158-576: The significance of the Bell Labs demonstration: "It was, in fact, the best demonstration of a mechanical television system ever made to this time. It would be several years before any other system could even begin to compare with it in picture quality." In 1928, WRGB , then W2XB, was started as the world's first television station. It broadcast from the General Electric facility in Schenectady, NY . It
15301-634: The spectrum of colors at the transmitting end and could not have worked as he described it. Another inventor, Hovannes Adamian , also experimented with color television as early as 1907. The first color television project is claimed by him, and was patented in Germany on 31 March 1908, patent No. 197183, then in Britain, on 1 April 1908, patent No. 7219, in France (patent No. 390326) and in Russia in 1910 (patent No. 17912). Scottish inventor John Logie Baird demonstrated
15444-546: The system was improved further by eliminating a motor generator so that his television system had no mechanical parts. That year, Farnsworth transmitted the first live human images with his system, including a three and a half-inch image of his wife Elma ("Pem") with her eyes closed (possibly due to the bright lighting required). Meanwhile, Vladimir Zworykin also experimented with the cathode-ray tube to create and show images. While working for Westinghouse Electric in 1923, he began to develop an electronic camera tube. However, in
15587-641: The takeover of Sky by Comcast in October 2018, Murdoch was no longer involved in British television but retained his newspaper assets through News Corp . As the company focused on the Astra system which was not subject to IBA regulation, the Marcopolo satellites were eventually withdrawn and later sold (Marcopolo 1 on 21 December 1993 to NSAB of Sweden and Marcopolo 2 on 1 July 1992 to Telenor of Norway). NSAB operated Marcopolo 1 (as Sirius 1) until successfully sending it to
15730-640: The technology used. Ironically the past-deadline encryption system in the D-MAC silicon chip technology was one primary reason for BSB having to merge with Sky, and hence the Far Eastern television manufacturers had largely unfettered access to the market when MAC was wound down in favour of PAL. After the merger, BSB D-MAC receivers were sold off cheaply and some enthusiasts modified them to allow reception of D2-MAC services available on other satellites. BSB receivers, Ferguson in particular, could be modified by replacing
15873-574: The television. He published an article on "Motion Pictures by Wireless" in 1913, transmitted moving silhouette images for witnesses in December 1923, and on 13 June 1925, publicly demonstrated synchronized transmission of silhouette pictures. In 1925, Jenkins used the Nipkow disk and transmitted the silhouette image of a toy windmill in motion over a distance of 5 miles (8 km), from a naval radio station in Maryland to his laboratory in Washington, D.C., using
16016-537: The term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the first International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris. The anglicized version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires ". It
16159-558: The top international formats. In 2010, CBS Studios International went into an equal joint venture with Reliance Broadcast Network Limited to form Big CBS Networks Pvt. Ltd . At the time, the network operated 3 main channels; Big CBS Prime , a general entertainment channel, Big CBS Spark , a youth-oriented channel and Big CBS Love , a women's and urban couple-oriented channel. In January 2011, CBS Studios International partnered with Australian company, Ten Network Holdings , to launch digital free-to-air channel known as Eleven and would hold
16302-513: The tube throughout each scanning cycle. The device was first described in a patent application he filed in Hungary in March 1926 for a television system he called "Radioskop". After further refinements included in a 1928 patent application, Tihanyi's patent was declared void in Great Britain in 1930, so he applied for patents in the United States. Although his breakthrough would be incorporated into
16445-485: The two remaining British high-powered DBS channels, beating six other bidders when the BBC dropped all plans for use of its allocated channels. BSB revised its line-up to include separate channels for films, sports, pop music, general entertainment and current affairs. Unfortunately, this increased the size of the dishes which the public had to purchase from 25 to 35–40 centimetres; subsidies from BSB helped maintain retail prices at £250. There were five satellite channels for
16588-513: The use of a CRT as a display device. The Braun tube became the foundation of 20th century television. In 1906 the Germans Max Dieckmann and Gustav Glage produced raster images for the first time in a CRT. In 1907, Russian scientist Boris Rosing used a CRT in the receiving end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen. In 1908, Alan Archibald Campbell-Swinton ,
16731-487: The widespread adoption of television. On 7 September 1927, U.S. inventor Philo Farnsworth 's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. By 3 September 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press. This is widely regarded as the first electronic television demonstration. In 1929,
16874-430: The work of Nipkow and others. However, it was not until 1907 that developments in amplification tube technology by Lee de Forest and Arthur Korn , among others, made the design practical. The first demonstration of the live transmission of images was by Georges Rignoux and A. Fournier in Paris in 1909. A matrix of 64 selenium cells, individually wired to a mechanical commutator , served as an electronic retina . In
17017-457: The world's first color transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color, and three light sources at the receiving end, with a commutator to alternate their illumination. Baird also made the world's first color broadcast on 4 February 1938, sending a mechanically scanned 120-line image from Baird's Crystal Palace studios to
17160-541: The world's first public demonstration of an all-electronic television system, using a live camera, at the Franklin Institute of Philadelphia on 25 August 1934 and for ten days afterward. Mexican inventor Guillermo González Camarena also played an important role in early television. His experiments with television (known as telectroescopía at first) began in 1931 and led to a patent for the "trichromatic field sequential system" color television in 1940. In Britain,
17303-458: Was "...formed in English or borrowed from French télévision ." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904)." The abbreviation TV is from 1948. The use of the term to mean "a television set " dates from 1941. The use of the term to mean "television as
17446-454: Was able, in his three well-known experiments, to deflect cathode rays, a fundamental function of the modern cathode-ray tube (CRT). The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the "Braun" tube. It was a cold-cathode diode , a modification of the Crookes tube , with a phosphor -coated screen. Braun was the first to conceive
17589-540: Was adopted by the Commission of the European Communities as the standard for all direct broadcast satellites. This had the effect that the low-cost non-European manufacturers would not only have to pay royalties to the manufacturers, but would also not have direct access to the technology, and hence would always be behind with new developments. In the United Kingdom, the Independent Broadcasting Authority developed
17732-509: Was considerably greater. It was used for outside broadcasting by the BBC, for the first time, on Armistice Day 1937, when the general public could watch on a television set as the King laid a wreath at the Cenotaph. This was the first time that anyone had broadcast a live street scene from cameras installed on the roof of neighboring buildings because neither Farnsworth nor RCA would do the same until
17875-637: Was designed in the Soviet Union in 1944 and became a national standard in 1946. The first broadcast in 625-line standard occurred in Moscow in 1948. The concept of 625 lines per frame was subsequently implemented in the European CCIR standard. In 1936, Kálmán Tihanyi described the principle of plasma display , the first flat-panel display system. Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes . Following
18018-534: Was due to start broadcasting in September 1989 but was delayed by problems with the supply of receiving equipment and because BSB wanted to avoid Sky's experience of launching when most shops had no equipment to sell. BSB claimed to have around 750,000 subscriptions while Sky had extended its reach into more than 1.5 million homes. It was believed both companies could break even if subscriptions reached three million households, with most analysts expecting this to be reached in 1992. Sky's head start over BSB proved that
18161-447: Was faced with an aggressive drive by Murdoch's Sky to be the first service to launch. As Britain's official satellite television provider, BSB had high hopes as the company planned to provide a mixture of highbrow programming and popular entertainment, from arts and opera to blockbuster movies and music videos. The service would also be technically superior, broadcasting in the D-MAC (Multiplexed Analogue Components type D) system dictated by
18304-496: Was folded into the company later in 2022. Viacom International Inc. was established in 1971, just a year after Viacom spun out from the CBS TV network and became Viacom's parent company. The company is responsible for copyrights and trademarks associated with its corporate websites, applications and cable networks, specifically its Media Networks division . The division also licenses the product rights for their various properties and
18447-669: Was managed by Bruce Gordon . The company co-produced The Lost Islands with the Ten Network (now Network 10 ) in 1975. Network 10 and this division have been in common ownership since 2019 after the ViacomCBS re-merger . In 1983, it acquired distribution rights to the Australian miniseries, Return to Eden . In 1968, Desilu was sold to Gulf+Western , the then-owners of the film studio Paramount Pictures , adding international television to its well-known film operations. Gulf+Western rebranded
18590-411: Was more reliable and visibly superior. This was the world's first regular "high-definition" television service. The original U.S. iconoscope was noisy, had a high ratio of interference to signal, and ultimately gave disappointing results, especially compared to the high-definition mechanical scanning systems that became available. The EMI team, under the supervision of Isaac Shoenberg , analyzed how
18733-422: Was not possible to sell a satellite dish and D-MAC standard receiver for £250. Australian businessman Alan Bond joined the consortium along with Reed Elsevier , Chargeurs , Next and London Merchant Securities , amongst others. BSB earmarked the bulk of the first round of financing for buying and launching two satellites (for redundancy and provision of further channels later) and planned a second round close to
18876-408: Was not until the 1990s that digital television became possible. Digital television was previously not practically possible due to the impractically high bandwidth requirements of uncompressed digital video , requiring around 200 Mbit/s for a standard-definition television (SDTV) signal, and over 1 Gbit/s for high-definition television (HDTV). A digital television service
19019-410: Was one by Maurice Le Blanc in 1880 for a color system, including the first mentions in television literature of line and frame scanning. Polish inventor Jan Szczepanik patented a color television system in 1897, using a selenium photoelectric cell at the transmitter and an electromagnet controlling an oscillating mirror and a moving prism at the receiver. But his system contained no means of analyzing
19162-842: Was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1,200 rpm and a similar disc spinning in synchronization in front of the cathode-ray tube inside the receiver set. The system was first demonstrated to the Federal Communications Commission (FCC) on 29 August 1940 and shown to the press on 4 September. CBS began experimental color field tests using film as early as 28 August 1940 and live cameras by 12 November. NBC (owned by RCA) made its first field test of color television on 20 February 1941. CBS began daily color field tests on 1 June 1941. These color systems were not compatible with existing black-and-white television sets , and, as no color television sets were available to
19305-518: Was popularly known as " WGY Television." Meanwhile, in the Soviet Union , Leon Theremin had been developing a mirror drum-based television, starting with 16 lines resolution in 1925, then 32 lines, and eventually 64 using interlacing in 1926. As part of his thesis, on 7 May 1926, he electrically transmitted and then projected near-simultaneous moving images on a 5-square-foot (0.46 m ) screen. By 1927 Theremin had achieved an image of 100 lines,
19448-405: Was precluded from buying a foreign satellite system. The IBA received five major contenders with serious bids for the direct broadcast satellite franchises. It also received submissions from The Children's Channel and ITN to make sure their programmes were used on any successful bid: British Satellite Broadcasting won the 15-year franchise on 11 December 1986 to operate the DBS system, with
19591-512: Was proposed in 1986 by Nippon Telegraph and Telephone (NTT) and the Ministry of Posts and Telecommunication (MPT) in Japan, where there were plans to develop an "Integrated Network System" service. However, it was not possible to implement such a digital television service practically until the adoption of DCT video compression technology made it possible in the early 1990s. In the mid-1980s, as Japanese consumer electronics firms forged ahead with
19734-423: Was reduced because payments became due only after the satellites were launched and operational. On 8 June 1988, rival tycoon Rupert Murdoch – having failed to gain regulatory approval for his satellite service to become part of the BSB consortium – announced that his pan-European television station Sky Channel , would be relaunched as a four-channel, United Kingdom-based service called Sky Television , using
19877-673: Was still hoping to launch in September 1989 but eventually had to admit that the launch would be delayed. By 22 July 1988 in a bid to gain more viewers, BSB and the BBC prepared a bid for a four-year deal for the rights to broadcast top league football, outbidding ITV's £44 million offer. BSB had also committed about £400 million to tie up the film libraries of Paramount , Universal , Columbia and MGM / United Artists , with total up-front payments of about £85 million. On 1 February 1989, BSB's costs had started to climb, reaching £354 million, while chief executive Anthony Simonds-Gooding denied that BSB had gone over budget and would require more than
20020-500: Was the desire to conserve bandwidth , potentially three times that of the existing black-and-white standards, and not use an excessive amount of radio spectrum . In the United States, after considerable research, the National Television Systems Committee approved an all-electronic system developed by RCA , which encoded the color information separately from the brightness information and significantly reduced
20163-409: Was transferred to CBS Corporation after CBS spun off from Viacom at the end of 2005, with television rights to the films from its sister company, Paramount Pictures , obtained by Trifecta Entertainment and Media . With the December 4, 2019 merger of CBS and Viacom, the TV rights to Paramount's films were brought back to the now-combined Paramount Global. The company distributes television content from
20306-500: Was unable or unwilling to introduce evidence of a working model of his tube that was based on his 1923 patent application. In September 1939, after losing an appeal in the courts and being determined to go forward with the commercial manufacturing of television equipment, RCA agreed to pay Farnsworth US$ 1 million over ten years, in addition to license payments, to use his patents. In 1933, RCA introduced an improved camera tube that relied on Tihanyi's charge storage principle. Called
20449-419: Was varied in proportion to the brightness of each spot on the image. As each hole in the disk passed by, one scan line of the image was reproduced. Baird's disk had 30 holes, producing an image with only 30 scan lines, just enough to recognize a human face. In 1927, Baird transmitted a signal over 438 miles (705 km) of telephone line between London and Glasgow . Baird's original 'televisor' now resides in
