By the mid-1990s, crime rates started to drop dramatically due to revised police strategies, improving economic opportunities, gentrification , and new residents, both American transplants and new immigrants from Asia and Latin America. New York City's population exceeded 8 million for the first time in the 2000 United States census ; further records were set in 2010 , and 2020 U.S. censuses. Important new sectors, such as Silicon Alley , emerged in

5995-961: The benefits of different calling plans. For example, a particular plan might provide for cheaper local calls, long-distance calls, international calls, or roaming. The mobile phone has been used in a variety of diverse contexts in society. For example: In 1998, one of the first examples of distributing and selling media content through the mobile phone was the sale of ringtones by Radiolinja in Finland. Soon afterwards, other media content appeared, such as news, video games, jokes, horoscopes, TV content and advertising. Most early content for mobile phones tended to be copies of legacy media , such as banner advertisements or TV news highlight video clips. Recently, unique content for mobile phones has been emerging, from ringtones and ringback tones to mobisodes , video content that has been produced exclusively for mobile phones. In many countries, mobile phones are used to provide mobile banking services, which may include

6104-583: The business elite lobbied for the establishment of Central Park , which in 1857 became the first landscaped park in an American city. The Great Irish Famine brought a large influx of Irish immigrants, of whom more than 200,000 were living in New York by 1860, representing over a quarter of the city's population. Extensive immigration from the German provinces meant that Germans comprised another 25% of New York's population by 1860. Democratic Party candidates were consistently elected to local office, increasing

6213-469: The call, from detecting the presence of a handset in a service area, temporary assignment of a channel to a handset making a call, interface with the land-line side of the network to connect to other subscribers, and collection of billing information for the service. The automation systems can control the "hand off" of a customer handset moving between one cell and another so that a call in progress continues without interruption, changing channels if required. In

7194-417: The development of large housing tracts in eastern Queens and Nassau County , with Wall Street leading America's place as the world's dominant economic power. The United Nations headquarters was completed in 1952, solidifying New York's global geopolitical influence, and the rise of abstract expressionism in the city precipitated New York's displacement of Paris as the center of the art world. In 1969,

7303-415: The earliest mobile phone systems by contrast, all control was done manually; the customer would search for an unoccupied channel and speak to a mobile operator to request connection of a call to a landline number or another mobile. At the termination of the call the mobile operator would manually record the billing information. Mobile phones communicate with cell towers that are placed to give coverage across

7412-418: The early 18th century, New York grew in importance as a trading port while as a part of the colony of New York . It became a center of slavery , with 42% of households enslaving Africans by 1730. Most were domestic slaves ; others were hired out as labor. Slavery became integrally tied to New York's economy through the labor of slaves throughout the port, and the banking and shipping industries trading with

7521-496: The end of 2009. In 2014, there were more than seven billion mobile phone subscribers worldwide, a number that is expected to keep growing. Mobile phones are used for a variety of purposes, such as keeping in touch with family members, for conducting business, and in order to have access to a telephone in the event of an emergency. Some people carry more than one mobile phone for different purposes, such as for business and personal use. Multiple SIM cards may be used to take advantage of

7630-531: The ergonomics associated with smaller 16:9 displays. Liquid-crystal displays are the most common; others are IPS , LED , OLED , and AMOLED displays. Some displays are integrated with pressure-sensitive digitizers, such as those developed by Wacom and Samsung , and Apple's " 3D Touch " system. In sound, smartphones and feature phones vary little. Some audio-quality enhancing features, such as Voice over LTE and HD Voice , have appeared and are often available on newer smartphones. Sound quality can remain

7739-420: The expected usage density, and may be much smaller in cities. In that case much lower transmitter powers are used to avoid broadcasting beyond the cell. In order to handle the high traffic, multiple towers can be set up in the same area (using different frequencies). This can be done permanently or temporarily such as at special events or in disasters. Cell phone companies will bring a truck with equipment to host

7848-486: The first quarter of 2016, the top smartphone developers worldwide were Samsung , Apple and Huawei ; smartphone sales represented 78 percent of total mobile phone sales. For feature phones as of 2016 , the top-selling brands were Samsung, Nokia and Alcatel . Mobile phones are considered an important human invention as they have been one of the most widely used and sold pieces of consumer technology. The growth in popularity has been rapid in some places, for example, in

7957-558: The former territory of New Netherland , including the city of New Amsterdam , when the Kingdom of England seized it from Dutch control. In the pre-Columbian era , the area of present-day New York City was inhabited by Algonquians , including the Lenape . Their homeland, known as Lenapehoking , included the present-day areas of Staten Island , Manhattan , the Bronx , the western portion of Long Island (including Brooklyn and Queens ), and

8066-593: The growth of bandwidth-intensive applications, such as streaming media . Consequently, the industry began looking to data-optimized fourth-generation ( 4G ) technologies, with the promise of speed improvements up to tenfold over existing 3G technologies. The first publicly available LTE service was launched in Scandinavia by TeliaSonera in 2009. In the 2010s, 4G technology has found diverse applications across various sectors, showcasing its versatility in delivering high-speed wireless communication, such as mobile broadband,

8175-466: The ice (and its subsequent retreat) contributed to the separation of what is now Long Island and Staten Island. That action left bedrock at a relatively shallow depth, providing a solid foundation for most of Manhattan's skyscrapers. The Hudson River flows through the Hudson Valley into New York Bay . Between New York City and Troy, New York , the river is an estuary . The Hudson River separates

8284-569: The influence of European companies had significantly decreased due to fierce competition from American and Asian companies, to where most technical innovation had shifted. Apple and Google, both of the United States, also came to dominate mobile phone software. The world's largest individual mobile operator by number of subscribers is China Mobile , which has over 902 million mobile phone subscribers as of June 2018 . Over 50 mobile operators have over ten million subscribers each, and over 150 mobile operators had at least one million subscribers by

8393-656: The island to England under the Treaty of Westminster of November 1674. Several intertribal wars among the Native Americans and epidemics brought on by contact with the Europeans caused sizeable population losses for the Lenape between 1660 and 1670. By 1700, the Lenape population had diminished to 200. New York experienced several yellow fever epidemics in the 18th century, losing ten percent of its population in 1702 alone. In

8502-662: The last Director-General of New Netherland. During his tenure, the population of New Netherland grew from 2,000 to 8,000. Stuyvesant has been credited with improving law and order; however, he earned a reputation as a despotic leader. He instituted regulations on liquor sales, attempted to assert control over the Dutch Reformed Church , and blocked other religious groups from establishing houses of worship. In 1664, unable to summon any significant resistance, Stuyvesant surrendered New Amsterdam to English troops, led by Colonel Richard Nicolls , without bloodshed. The terms of

8611-414: The local cell and in the adjacent cells. However, cells further away can re-use that channel without interference as the subscriber's handset is too far away to be detected. The transmitter power of each base station is coordinated to efficiently service its own cell, but not to interfere with the cells further away. Automation embedded in the customer's handset and in the base stations control all phases of

8720-545: The local population as a representative of the Dutch colonists. A permanent European presence near New York Harbor was established in 1624, making New York the 12th-oldest continuously occupied European-established settlement in the continental United States , with the founding of a Dutch fur trading settlement on Governors Island . In 1625, construction was started on a citadel and Fort Amsterdam , later called Nieuw Amsterdam (New Amsterdam), on present-day Manhattan Island. The colony of New Amsterdam extended from

8829-419: The most populous urbanized area in the world in the early 1920s, overtaking London . The metropolitan area surpassed 10 million in the early 1930s, becoming the first megacity . The Great Depression saw the election of reformer Fiorello La Guardia as mayor and the fall of Tammany Hall after eighty years of political dominance. Returning World War II veterans created a post-war economic boom and

8938-544: The mouth of the Hudson River , which feeds into a naturally sheltered harbor and then into the Atlantic Ocean , has helped the city grow in significance as a trading port. Most of the city is built on the three islands of Long Island, Manhattan, and Staten Island. During the Wisconsin glaciation , 75,000 to 11,000 years ago, the New York City area was situated at the edge of a large ice sheet . The erosive forward movement of

9047-477: The new meters charged 25¢ an hour. A March 2014 study found that SFpark met its 60–80% occupancy goal and that cruising for parking is down by 50%. A 2016 economic study found a dramatic positive benefit of the SFpark Project: subsequent price changes squeeze more blocks into the target occupancy range of 60–80%, reducing the number of blocks with very high or very low occupancy rates as well as, more generally,

9156-523: The number of blocks not meeting occupancy goals. The study notes that this finding does not mean that the occupancy rate on any particular block is more stable but rather that overall variability in occupancy rates across blocks decreases, on average, through performance-based price changes. If individuals can more reliably and quickly find parking spaces (i.e. if target occupancy rates are met more frequently on aggregate), then each vehicle trip does not need to be padded with additional travel time to "cruise" for

9265-447: The on-street parking, fourteen city-owned garages are included in the program. This concept of market-based variable pricing or "performance parking" has long been advocated by transportation researcher Donald Shoup , now an adviser on the project. By December 2012, average hourly parking rates had dropped by 14 cents from $ 2.73 to $ 2.59, SFMTA's revenue from parking citations dropped from 45% to 20% of total parking revenue, and 6% of

9374-492: The only " transgender folks around" during the June 1969 Stonewall riots. The transgender community in New York City played a significant role in fighting for LGBT equality. In the 1970s, job losses due to industrial restructuring caused New York City to suffer from economic problems and rising crime rates. Growing fiscal deficits in 1975 led the city to appeal to the federal government for financial aid; President Gerald Ford gave

9483-399: The phone and the point of sale support near field communication (NFC). Enabling contactless payments through NFC-equipped mobile phones requires the co-operation of manufacturers, network operators, and retail merchants. Mobile phones are commonly used to collect location data. While the phone is turned on, the geographical location of a mobile phone can be determined easily (whether it

9592-567: The phone close to the ear. The average phone battery lasts two–three years at best. Many of the wireless devices use a Lithium-Ion (Li-Ion) battery, which charges 500–2500 times, depending on how users take care of the battery and the charging techniques used. It is only natural for these rechargeable batteries to chemically age, which is why the performance of the battery when used for a year or two will begin to deteriorate. Battery life can be extended by draining it regularly, not overcharging it, and keeping it away from heat. Mobile phones require

9701-697: The press in North America . In 1754, Columbia University was founded. The Stamp Act Congress met in New York in October 1765, as the Sons of Liberty organization emerged in the city and skirmished over the next ten years with British troops stationed there. The Battle of Long Island , the largest battle of the American Revolutionary War , was fought in August 1776 within modern-day Brooklyn. A British rout of

9810-523: The region for the Dutch East India Company. In 1614, the area between Cape Cod and Delaware Bay was claimed by the Netherlands and called Nieuw-Nederland (' New Netherland '). The first non–Native American inhabitant of what became New York City was Juan Rodriguez , a merchant from Santo Domingo who arrived in Manhattan during the winter of 1613–14, trapping for pelts and trading with

9919-545: The second-generation ( 2G ) digital cellular technology was launched in Finland by Radiolinja on the GSM standard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators. The GSM standard is a European initiative expressed at the CEPT ("Conférence Européenne des Postes et Telecommunications", European Postal and Telecommunications conference). The Franco-German R&D cooperation demonstrated

10028-596: The southern tip of Manhattan to modern-day Wall Street , where a 12-foot (3.7 m) wooden stockade was built in 1653 to protect against Native American and English raids. In 1626, the Dutch colonial Director-General Peter Minuit , as charged by the Dutch West India Company , purchased the island of Manhattan from the Canarsie , a small Lenape band, for "the value of 60 guilders " (about $ 900 in 2018). A frequently told but disproved legend claims that Manhattan

10137-497: The surrender permitted Dutch residents to remain in the colony and allowed for religious freedom. In 1667, during negotiations leading to the Treaty of Breda after the Second Anglo-Dutch War , the victorious Dutch decided to keep the nascent plantation colony of what is now Suriname , which they had gained from the English, and in return the English kept New Amsterdam. The settlement was promptly renamed "New York" after

10246-401: The technical feasibility, and in 1987, a Memorandum of Understanding was signed between 13 European countries that agreed to launch a commercial service by 1991. The first version of the GSM standard had 6,000 pages. The IEEE and RSE awarded Thomas Haug and Philippe Dupuis the 2018 James Clerk Maxwell medal for their contributions to the first digital mobile telephone standard. In 2018,

10355-699: The use of native software applications are known as smartphones . The first GSM phones and many feature phones had NOR flash memory, from which processor instructions could be executed directly in an execute in place architecture and allowed for short boot times. With smartphones, NAND flash memory was adopted as it has larger storage capacities and lower costs, but causes longer boot times because instructions cannot be executed from it directly, and must be copied to RAM memory first before execution. Mobile phones have central processing units (CPUs), similar to those in computers, but optimised to operate in low power environments. Mobile CPU performance depends not only on

10464-578: The world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m), a reference to the year of U.S. independence . The Occupy Wall Street protests in Zuccotti Park in the Financial District of Lower Manhattan began on September 17, 2011, receiving global attention and popularizing the Occupy movement against social and economic inequality worldwide. New York City

10573-483: The world's two largest stock exchanges by market capitalization of their listed companies: the New York Stock Exchange and Nasdaq . New York City is an established safe haven for global investors. As of 2023 , New York City is the most expensive city in the world for expatriates and has by a wide margin the highest U.S. city residential rents; and Fifth Avenue is the most expensive shopping street in

10682-521: The world. New York City traces its origins to Fort Amsterdam and a trading post founded on Manhattan Island by Dutch colonists around 1624. The settlement was named New Amsterdam in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was temporarily renamed New York after King Charles II granted the lands to his brother, the Duke of York , before being permanently renamed New York in November 1674. New York City

10791-402: The world. New York City is home by a significant margin to the highest number of billionaires , individuals of ultra-high net worth (greater than US$ 30 million), and millionaires of any city in the world. In 1664, New York was named in honor of the Duke of York (later King James II of England ). James's elder brother, King Charles II , appointed the Duke as proprietor of

10900-552: Was heavily affected by Hurricane Sandy in late October 2012. Sandy's impacts included flooding that led to the days-long shutdown of the subway system and flooding of all East River subway tunnels and of all road tunnels entering Manhattan except the Lincoln Tunnel . The New York Stock Exchange closed for two days due to weather for the first time since the Great Blizzard of 1888 . At least 43 people died in New York City as

11009-525: Was a haven for Loyalist refugees and escaped slaves who joined the British lines for freedom promised by the Crown , with as many as 10,000 escaped slaves crowded into the city during the British occupation, the largest such community on the continent. When the British forces evacuated New York at the close of the war in 1783, they transported thousands of freedmen for resettlement in Nova Scotia , England, and

11118-525: Was a prime destination in the early 20th century for Blacks during the Great Migration from the American South, and by 1916, New York City had the largest urban African diaspora in North America. The Harlem Renaissance of literary and cultural life flourished during the era of Prohibition . The larger economic boom generated construction of skyscrapers competing in height. New York City became

11227-412: Was attributed to the desire to obtain the lowest calling costs. When the removal of a SIM card is detected by the operating system, it may deny further operation until a reboot. Feature phones have basic software platforms. Smartphones have advanced software platforms. Android OS has been the best-selling OS worldwide on smartphones since 2011. A mobile app is a computer program designed to run on

11336-575: Was demonstrated by Martin Cooper of Motorola in New York City on 3 April 1973, using a handset weighing c. 2 kilograms (4.4 lbs). In 1979, Nippon Telegraph and Telephone (NTT) launched the world's first cellular network in Japan. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion; enough to provide one for every person on Earth. In

11445-540: Was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway, and Sweden. Several other countries then followed in the early to mid-1980s. These first-generation ( 1G ) systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. In 1991,

11554-499: Was launched in Finland in 2000, and subsequently many organizations provided "on-demand" and "instant" news services by SMS. Multimedia Messaging Service (MMS) was introduced in March 2002. The introduction of Apple's App Store for the iPhone and iPod Touch in July 2008 popularized manufacturer-hosted online distribution for third-party applications (software and computer programs) focused on

11663-504: Was market leader in mobile phones. Nokia was the market leader in mobile phones from 1998 to 2012. In Q1 2012, Samsung surpassed Nokia, selling 93.5 million units as against Nokia's 82.7 million units. Samsung has retained its top position since then. Aside from Motorola, European brands such as Nokia, Siemens and Ericsson once held large sway over the global mobile phone market, and many new technologies were pioneered in Europe. By 2010,

11772-415: Was purchased for $ 24 worth of glass beads. Following the purchase, New Amsterdam grew slowly. To attract settlers, the Dutch instituted the patroon system in 1628, whereby wealthy Dutchmen ( patroons , or patrons) who brought 50 colonists to New Netherland would be awarded land, local political autonomy, and rights to participate in the lucrative fur trade. This program had little success. Since 1621,

11881-417: Was the U.S. capital from 1785 until 1790. The modern city was formed by the 1898 consolidation of its five boroughs : Manhattan , Brooklyn , Queens , the Bronx , and Staten Island . Anchored by Wall Street in the Financial District, Manhattan , New York City has been called both the world's premier financial and fintech center and the most economically powerful city in the world. As of 2022 ,
