iPhone History

Development of the iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens. Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house.

Jobs unveiled the iPhone to the public on January 9, 2007 at Macworld 2007. Apple was required to file for operating permits with the FCC, but since such filings are made available to the public, the announcement came months before the iPhone had received approval. The iPhone went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide. The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six. Apple released the iPhone 3G in upwards of eighty countries and territories. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost, and 40% of users have household incomes over US$100,000. In an attempt to gain a wider market, Apple retained the 8 GB iPhone 3G at a lower price point. When Apple introduced the iPhone 4, the 3GS became the less expensive model. Apple reduced the price several times since the iPhone's release in 2007, at which time an 8 GB iPhone sold for $599. An iPhone 3GS with the same capacity now costs $99. However, these numbers are misleading, since all iPhone units sold through AT&T require a two-year contract (costing several hundred dollars), and a SIM lock.

Apple sold 6.1 million original iPhone units over five quarters. The sales has been growing steadily thereafter, by the end of fiscal year 2010, a total of 73.5 million iPhones were sold. Sales in Q4 2008 surpassed temporarily those of RIM's BlackBerry sales of 5.2 million units, which made Apple briefly the third largest mobile phone manufacturer by revenue, after Nokia and Samsung. Approximately 6.4 million iPhones are active in the U.S. alone. While iPhone sales constitute a significant portion of Apple's revenue, some of this income is deferred.

The back of the original iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. They both are now discontinued. The iPhone 3GS was available in both colors, regardless of storage capacity. The white model was discontinued in favor of a black 8 GB low-end model. The iPhone 4 has an aluminosilicate glass front and back with a stainless steel edge that serves as the antennae. It is available in black; a white version was announced, but has as of October 2010 not been released.

The iPhone has garnered positive reviews from critics like David Pogue and Walter Mossberg. The iPhone attracts users of all ages, and besides consumer use the iPhone has also been adopted for business purposes.

Camcorder History

Video cameras originally designed for television broadcast were large and heavy, mounted on special pedestals, and wired to remote recorders located in separate rooms.

As technology advanced, out-of-studio video recording was made possible by means of compact video cameras and portable video recorders. The recording unit could be detached from the camera and carried to a shooting location. While the camera itself could be quite compact, the fact that a separate recorder had to be carried along made on-location shooting a two-man job. Specialized video cassette recorders were introduced by both JVC (VHS) and Sony (U-matic and Betamax) to be used for mobile work. The advent of the portable recorders helped to eliminate the phrase "film at eleven"—rather than wait for the lengthy process of film developing, recorded video could be shown during the 6 o'clock news.

In 1982 Sony released the Betacam system. A part of this system was a single camera-recorder unit, which eliminated the cable between camera and recorder and dramatically improved the freedom of a cameraman. Betacam quickly became the standard for both news-gathering and in-studio video editing.

In 1983 Sony released the first consumer camcorder—the Betamovie BMC-100P. It used a Betamax cassette and could not be held with one hand, so it was typically resting on a shoulder. In the same year JVC released the first camcorder based on VHS-C format.[8] In 1985 Sony came up with its own compact video cassette format—Video8. Both formats had their benefits and drawbacks, and neither won the format war.

In 1985, Panasonic, RCA, and Hitachi began producing camcorders that recorded to full-sized VHS cassette and offered up to 3 hours of record time. These shoulder mount camcorders found a niche with videophiles, industrial videographers, and college TV studios. Super VHS full-sized camcorders were released in 1987 which exceeded broadcast quality and provided an inexpensive way to collect news segments or videographies.

In 1986 Sony introduced the first digital video format, D1. Video was recorded in uncompressed form and required enormous bandwidth for its time. In 1992 Ampex used D1 form-factor to create DCT, the first digital video format that utilized data compression. The compression utilized discrete cosine transform algorithm, which is used in most modern commercial digital video formats.

In 1995 Sony, JVC, Panasonic and other video camera manufacturers launched DV. Its variant using a smaller MiniDV cassette quickly became a de-facto standard for home and semi-professional video production, for independent filmmaking and for citizen journalism.

In 2000 Panasonic launched DVCPRO HD, expanding DV codec to support high definition. The format was intended for use in professional camcorders and used full-size DVCPRO cassettes. In 2003 Sony, JVC, Canon and Sharp introduced HDV, the first truly affordable high definition video format, which used inexpensive MiniDV cassettes.

In 2003 Sony pioneered XDCAM, the first tapeless video format, which uses Professional Disc as recording media. Panasonic followed next year, offering P2 solid state memory cards as recording medium for DVCPRO HD video.

In 2006 Panasonic and Sony introduced AVCHD as an inexpensive consumer-grade tapeless high definition video format. Presently AVCHD camcorders are manufactured by Sony, Panasonic, Canon, JVC and Hitachi.

In 2007 Sony introduced XDCAM EX, which offers similar recording modes to XDCAM HD, but records on SxS memory cards.

With proliferation of file-based digital formats the relationship between recording media and recording format became weaker than ever: the same video can be recorded onto different media. With tapeless formats, recording media has become a storage device for digital files, signifying convergence of video and computer industries.

Camera History

The forerunner to the camera was the camera obscura. It was a dark chamber (in Latin, a camera obscura, demonstrating the etymology), "consist[ing] of a darkened chamber or box, into which light is admitted through a pinhole (later a convex lens), forming an image of external objects on a surface of paper or glass, etc., placed at the focus of the lens". In the 6th century, Greek mathematician and architect Anthemius of Tralles used a type of camera obscura in his experiments. The camera obscura was described by the Arabic scientist Ibn al-Haytham (Alhazen) in his Book of Optics (1015–1021). Scientist-monk Roger Bacon also studied the matter. The actual name of camera obscura was applied by mathematician and astronomer Johannes Kepler in his Ad Vitellionem paralipomena of 1604. He later added a lens and made the apparatus transportable, in the form of a tent. English scientist Robert Boyle and his assistant Robert Hooke developed a portable camera obscura in the 1660s.

The first camera obscura that was small and portable enough for practical use was built by Johann Zahn in 1685. At this time there was no way to preserve the images produced by these cameras apart from manually tracing them. However, in 1724, Johann Heinrich Schultz discovered that a silver and chalk mixture darkens under exposure to light. Early photography built on these discoveries and developments. The early photographic cameras were essentially similar to Zahn's camera obscura, though usually with the addition of sliding boxes for focusing. Before each exposure, a sensitized plate would be inserted in front of the viewing screen to record the image. The first permanent photograph was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris and building on Johann Heinrich Schultz's discovery about silver and chalk mixtures darkening when exposed to light. Jacques Daguerre's popular daguerreotype process utilized copper plates, while the calotype process invented by William Fox Talbot recorded images on paper.
The first permanent color photograph, taken by James Clerk Maxwell in 1861.

The development of the collodion wet plate process by Frederick Scott Archer in 1850 cut exposure times dramatically, but required photographers to prepare and develop their glass plates on the spot, usually in a mobile darkroom. Despite their complexity, the wet-plate ambrotype and tintype processes were in widespread use in the latter half of the 19th century. Wet plate cameras were little different from previous designs, though there were some models, such as the sophisticated Dubroni of 1864, where the sensitizing and developing of the plates could be carried out inside the camera itself rather than in a separate darkroom. Other cameras were fitted with multiple lenses for making cartes de visite. It was during the wet plate era that the use of bellows for focusing became widespread.

The first color photograph was made by Scottish physicist James Clerk Maxwell, with the help of English inventor and photographer Thomas Sutton, in 1861.
The electronic video camera tube was invented in the 1920s, starting a line of development that eventually resulted in digital cameras, which largely supplanted film cameras after the turn of the 21st century.

Smartphone History

Early years
The first smartphone was called Simon; it was designed by IBM in 1992 and shown as a concept product that year at COMDEX, the computer industry trade show held in Las Vegas, Nevada. It was released to the public in 1993 and sold by BellSouth. Besides being a mobile phone, it also contained a calendar, address book, world clock, calculator, note pad, e-mail, send and receive fax, and games. It had no physical buttons to dial with. Instead customers used a touchscreen to select telephone numbers with a finger or create facsimiles and memos with an optional stylus. Text was entered with a unique on-screen "predictive" keyboard. By today's standards, the Simon would be a fairly low-end product; however, its feature set at the time was highly advanced.

The Nokia Communicator line was the first of Nokia's smartphones starting with the Nokia 9000, released in 1996. This distinctive palmtop computer style smartphone was the result of a collaborative effort of an early successful and costly personal digital assistant (PDA) by Hewlett Packard combined with Nokia's bestselling phone around that time, and early prototype models had the two devices fixed via a hinge. The Nokia 9210 was the first color screen Communicator model which was the first true smartphone with an open operating system; the 9500 Communicator was also Nokia's first cameraphone Communicator and Nokia's first WiFi phone. The 9300 Communicator was the third dimensional shift into a smaller form factor, and the latest E90 Communicator includes GPS. The Nokia Communicator model is remarkable for also having been the most costly phone model sold by a major brand for almost the full life of the model series, costing easily 20% and sometimes 40% more than the next most expensive smartphone by any major producer.

In 1997 Ericsson released the concept phone GS88,[8][9] the first device labelled as 'smartphone'.

Rise of Symbian and BlackBerry
In 2000 Ericsson released the touchscreen smartphone R380, the first device to use the new Symbian OS. It was followed up by P800 in 2002, the first camera smartphone.
In 2001 Microsoft announced its Windows CE Pocket PC OS would be offered as "Microsoft Windows Powered Smartphone 2002." Microsoft originally defined its Windows Smartphone products as lacking a touchscreen and offering a lower screen resolution compared to its sibling Pocket PC devices.

In early 2002 Handspring released the Palm OS Treo smartphone, utilizing a full keyboard that combined wireless web browsing, email, calendar, and contact organizer with mobile third-party applications that could be downloaded or synced with a computer.
In 2002 RIM released the first BlackBerry which was the first smartphone optimized for wireless email use and had achieved a total customer base of 32 million subscribers by December 2009.
In 2007 Nokia launched the Nokia N95 which integrated a wide range of features into a consumer-oriented smartphone: GPS, a 5 megapixel camera with autofocus and LED flash, 3G and wi-fi connectivity and TV-out. In the next few years these features would become standard on high-end smartphones.

In 2010 Nokia released the Nokia N8 smartphone, the first device to use the new Symbian^3 OS. It featured a camera that Mobile Burn described as the best camera in a phone, and satellite navigation that Mobile Choice described as the best on any phone.

Later in 2007, Apple Inc. introduced its first iPhone. It was initially costly, priced at $500 for the cheaper of two models on top of a two year contract. It was one of the first smartphones to be mainly controlled through its touchscreen, the others being the LG Prada and the HTC Touch (also released in 2007). It was the first mobile phone to use a multi-touch interface, and it featured a web browser that Ars Technica then described as "far superior" to anything offered by that of its competitors. At the time of the launch of the iPhone it was arguable whether it was actually a smartphone as the first generation lacked the ability to officially use third-party applications. A process called jailbreaking emerged quickly to provide unofficial third-party applications. Steve Jobs publicly stated that the iPhone lacked 3G support due to the immaturity, power use, and physical size requirements of 3G chipsets at the time. However, it has been rumored that the CDMA2000 Network Providers (Verizon, Sprint) refused to allow the iPhone on their network because Jobs wanted total control of the application store associated with the iPhone.

Android, a cross platform OS for smartphones was released in 2008. Android is an open source platform backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Motorola and Samsung, to name a few), that form the Open Handset Alliance. The first phone to use the Android OS was the HTC Dream, branded for distribution by T-Mobile as the G1. The software suite included on the phone consists of integration with Google's proprietary applications, such as Maps, Calendar, and Gmail, and a full HTML web browser. Third-party apps are available via the Android Market (released October 2008), including both free and paid apps. 

In July 2008, Apple introduced its second generation iPhone which had a lower list price and 3G support. Released with it, Apple also created the App Store with both free and paid applications. The App Store can deliver smartphone applications developed by third parties directly to the iPhone or iPod Touch over wifi or cellular network without using a PC to download. The App Store has been a huge success for Apple and by April 2010 hosted more than 185,000 applications. The App Store hit three billion application downloads in early January 2010.

In January 2010, Google launched the Nexus One using its Android OS. Although Android has multi-touch capabilities, Google initially removed that feature from the Nexus One, but it was added through a firmware update on February 2, 2010.

According to Gartner in their report dated November 2010, total smartphone sales doubled in one year and now smartphones represent 19.3 percent of total mobile phone sales. Over late 2009 and 2010 Android's smartphone market share has increased very rapidly.

Cell Phone History

Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s.

The first mobile telephone call made from a car occurred in St. Louis, Missouri, USA on June 17, 1946, using the Bell System's Mobile Telephone Service, but the system was impractical from what is considered a portable handset today. The equipment weighed 80 lbs, and the AT&T service, basically a massive party line, cost $30 USD per month (equal to $337.33 today) plus 30 to 40 cents per local call, equal to $3.37 to $4.5 today.
In 1960, the world’s first partly automatic car phone system, Mobile System A (MTA), was launched in Sweden. MTA phones were composed of vacuum tubes and relays, and had a weight of 40 kg. In 1962, a more modern version called Mobile System B (MTB) was launched, which was a push-button telephone, and which used transistors in order to enhance the telephone’s calling capacity and improve its operational reliability. In 1971, the MTD version was launched, opening for several different brands of equipment and gaining commercial success.
Martin Cooper, a Motorola researcher and executive is considered to be the inventor of the first practical mobile phone for handheld use in a non-vehicle setting, after a long race against Bell Labs for the first portable mobile phone. Using a modern, if somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on April 3, 1973 to his rival, Dr. Joel S. Engel of Bell Labs.
The first commercially automated cellular network (the 1G generation) was launched in Japan by NTT in 1979, initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden.[8] NMT was the first mobile phone network featuring international roaming. The first 1G network launched in the USA was Chicago-based Ameritech in 1983 using the Motorola DynaTAC mobile phone. Several countries then followed in the early-to-mid 1980s including the UK, Mexico and Canada.

The first "modern" network technology on digital 2G (second generation) cellular technology was launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard, which also marked the introduction of competition in mobile telecoms when Radiolinja challenged incumbent Telecom Finland (now part of TeliaSonera) who ran a 1G NMT network.

In 2001, the first commercial launch of 3G (Third Generation) was again in Japan by NTT DoCoMo on the WCDMA standard.
One of the newest 3G technologies to be implemented is High-Speed Downlink Packet Access (HSDPA). It is an enhanced 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, also coined 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity.
