History

The PlayStation 2 (PS2) is a home video game console that was developed by Sony Computer Entertainment. It is the successor to the PlayStation and is the second installment in the PlayStation lineup of consoles. It was released in 2000 and competed with Sega's Dreamcast, Nintendo's GameCube and Microsoft's Xbox in the sixth generation of video game consoles.

Announced in 1999, the PlayStation 2 offered backwards compatibility for its DualShock controller, as well as for its games. The PlayStation 2 is the best-selling video game console of all time, selling over 155 million units, with 150 million confirmed by Sony in 2011. More than 3,874 game titles have been released for the PS2 since launch, and more than 1.5 billion copies have been sold. Sony later manufactured several smaller, lighter revisions of the console known as Slimline models in 2004. In 2006, Sony announced and launched its successor, the PlayStation 3.

Even with the release of its successor, the PlayStation 2 remained popular well into the seventh generation and continued to be produced until January 4, 2013, when Sony finally announced that the PlayStation 2 had been discontinued after 12 years of production – one of the longest runs for a video game console. Despite the announcement, new games for the console continued to be produced until the end of 2013, including Final Fantasy XI: Seekers of Adoulin for Japan, FIFA 13 for North America, and Pro Evolution Soccer 2014 for Europe. Repair services for the system ended on September 7, 2018.   Though Sony has kept details of the PlayStation 2's development secret, work on the console began around the time that the original PlayStation was released (in late 1994). Insiders stated that it was developed in the U.S. West Coast by former members of Argonaut Software. By 1997 word had leaked to the press that the console would have backwards compatibility with the original PlayStation, a built-in DVD player, and Internet connectivity. Sony announced the PlayStation 2 (PS2) on March 1, 1999. The video game console was positioned as a competitor to Sega's Dreamcast, the first sixth-generation console to be released, although ultimately the main rivals of the PS2 were Nintendo's GameCube and Microsoft's Xbox. The Dreamcast itself launched very successfully in North America later that year, selling over 500,000 units within two weeks.

Soon after the Dreamcast's North American launch, Sony unveiled the PlayStation 2 at the Tokyo Game Show on September 20, 1999. Sony showed fully playable demos of upcoming PlayStation 2 games including Gran Turismo 2000 (later released as Gran Turismo 3: A-Spec) and Tekken Tag Tournament – which showed the console's graphic abilities and power.

The PS2 was launched in March 2000 in Japan, October in North America, and November in Europe. Sales of the console, games and accessories pulled in $250 million on the first day, beating the $97 million made on the first day of the Dreamcast. Directly after its release, it was difficult to find PS2 units on retailer shelves due to manufacturing delays. Another option was purchasing the console online through auction websites such as eBay, where people paid over a thousand dollars for the console. The PS2 initially sold well partly on the basis of the strength of the PlayStation brand and the console's backward compatibility, selling over 980,000 units in Japan by March 5, 2000, one day after launch.This allowed the PS2 to tap the large install base established by the PlayStation – another major selling point over the competition. Later, Sony added new development kits for game developers and more PS2 units for consumers. The PS2's built-in functionality also expanded its audience beyond the gamer, as its debut pricing was the same or less than a standalone DVD player. This made the console a low cost entry into the home theater market.

The success of the PS2 at the end of 2000 caused Sega problems both financially and competitively, and Sega announced the discontinuation of the Dreamcast in March 2001, just 18 months after its successful launch. The PS2 remained as the only active sixth generation console for over 6 months, before it would face competition from newer rivals; Nintendo's GameCube and Microsoft's Xbox, which were then released. Many analysts predicted a close three-way matchup among the three consoles; the Xbox having the most powerful hardware, while the GameCube was the least expensive console, and Nintendo changed its policy to encourage third-party developers. While the PlayStation 2 theoretically had the weakest specification of the three, it had a head start due to its installed base plus strong developer commitment, as well as a built-in DVD player (the Xbox required an adapter, while the GameCube lacked support entirely). While the PlayStation 2's initial games lineup was considered mediocre, this changed during the 2001 holiday season with the release of several blockbuster games that maintained the PS2's sales momentum and held off its newer rivals. Sony also countered the Xbox by temporarily securing PlayStation 2 exclusives for highly anticipated games such as the Grand
Theft Auto series and Metal Gear Solid 2: Sons of Liberty.

Sony cut the price of the console in May 2002 from US$299 to $199 in North America, making it the same price as the GameCube and $100 less than the Xbox. It also planned to cut the price in Japan around that time.[30] It cut the price twice in Japan in 2003.In 2006, Sony cut the cost of the console in anticipation of the release of the PlayStation 3.

Sony, unlike Sega with its Dreamcast, originally placed little emphasis on online gaming during its first few years, although that changed upon the launch of the online-capable Xbox. Coinciding with the release of Xbox Live, Sony released the PlayStation Network Adapter in late 2002, with several online first–party titles released alongside it, such as SOCOM: U.S. Navy SEALs to demonstrate its active support for Internet play.[citation needed] Sony also advertised heavily, and its online model had the support of Electronic Arts (EA); EA did not offer online Xbox titles until 2004. Although Sony and Nintendo both started out late, and although both followed a decentralized model of online gaming where the responsibility is up to the developer to provide the servers, Sony's moves made online gaming a major selling point of the PS2.

In September 2004, in time for the launch of Grand Theft Auto: San Andreas, Sony revealed a newer, slimmer PS2. In preparation for the launch of the new models (SCPH-700xx-9000x), Sony stopped making the older models (SCPH-3000x-500xx) to let the distribution channel empty its stock of the units.[citation needed] After an apparent manufacturing issue – Sony reportedly underestimated demand – caused some initial slowdown in producing the new unit caused in part by shortages between the time the old units were cleared out and the new units were ready. The issue was compounded in Britain when a Russian oil tanker became stuck in the Suez Canal, blocking a ship from China carrying PS2s bound for the UK. During one week in November, British sales totalled 6,000 units – compared to 70,000 units a few weeks prior. There were shortages in more than 1,700 stores in North America on the day before Christmas PlayStation 2 software is distributed on CD-ROM and DVD-ROM. In addition the console can play audio CDs and DVD movies, and is backwards compatible with PlayStation games. The PS2 also supports PlayStation memory cards and controllers, although original PlayStation memory cards only work with original PlayStation games and the controllers may not support all functions (such as analog buttons) for PS2 games.

The standard PlayStation 2 memory card has an 8 MB capacity. There are a variety of non-Sony manufactured memory cards available for the PlayStation 2, allowing for a memory capacity larger than the standard 8 MB.

The console also features USB and IEEE 1394 (Firewire) expansion ports. A hard disk drive can be installed in an expansion bay on the back of the console, and is required to play certain games, notably the popular Final Fantasy XI.This is only available on certain models.

Hardware

The hardware uses the Emotion Engine CPU, a custom-designed processor based on the MIPS architecture with a floating point performance of 6.2 GFLOPS, and the custom-designed Graphics Synthesizer GPU, with a fillrate of 2.4 gigapixels/second, capable of rendering up to 75 million polygons per second.[35] When accounting for features such as lighting, texture mapping, artificial intelligence, and game physics, it has a real-world performance of 3 million to 16 million polygons per second.

Audio/video
The PlayStation 2 may natively output video resolutions on SDTV and HDTV from 480i to 480p while other games, such as Gran Turismo 4 and Tourist Trophy are known to support up-scaled 1080i resolution using any of the following standards: composite video (480i), S-Video (480i), RGB (480i/p), VGA (for progressive scan games and PS2 Linux only), YPBPR component video (which display most original PlayStation games in their native 240p mode which most HDTV sets do not support), and D-Terminal. Cables are available for all of these signal types; these cables also output analog stereo audio. Additionally, an RF modulator is available for the system to connect to older TVs.

Digital (S/PDIF) audio may also be output by the console via its TOSLINK connector which outputs 5.1 channel sound. Retail configurations

The PS2's controller, the DualShock 2, had the same form factor as the PlayStation DualShock.
The PS2 has undergone many revisions, some only of internal construction and others involving substantial external changes.

The PS2 is primarily differentiated between models featuring the original "fat" case design and "slimline" models, which were introduced at the end of 2004. In 2010, the Sony Bravia KDL-22PX300 was made available to consumers. It was a 22" HD-Ready television which incorporated a built-in PlayStation 2.

The PS2 standard color is matte black. Several variations in color were produced in different quantities and regions, including ceramic white, light yellow, metallic blue (aqua), metallic silver, navy (star blue), opaque blue (astral blue), opaque black (midnight black), pearl white, sakura purple, satin gold, satin silver, snow white, super red, transparent blue (ocean blue), and also Limited Edition color Pink, which was distributed in some regions such as Oceania, and parts of Asia.

In September 2004, Sony unveiled its third major hardware revision. Available in late October 2004, it was smaller, thinner, and quieter than the original versions and included a built-in Ethernet port (in some markets it also had an integrated modem). Due to its thinner profile, it did not contain the 3.5" expansion bay and therefore did not support the internal hard disk drive. It also lacked an internal power supply until a later revision (excluding the Japan version), similar to the GameCube, and had a modified Multitap expansion. The removal of the expansion bay was criticized as a limitation due to the existence of titles such as Final Fantasy XI, which required the use of the HDD.

Sony also manufactured a consumer device called the PSX that can be used as a digital video recorder and DVD burner in addition to playing PS2 games. The device was released in Japan on December 13, 2003, and was the first Sony product to include the XrossMediaBar interface. It did not sell well in the Japanese market and was not released anywhere else.

Disc Read Error (DRE) lawsuit
A class action lawsuit was filed against Sony Computer Entertainment America Inc. on July 16, 2002, in the Superior Court of California, County of San Mateo. The lawsuit addresses consumer reports of inappropriate "no disc error" (disc read error) messages and other problems associated with playing DVDs and CDs on the PlayStation 2.

Sony settled its "disc read error" lawsuit by compensating the affected customers with USD $25, a free game from a specified list, and the reduced cost repair or replacement (at SCEA's discretion) of the damaged system. This settlement was subject to the courts' approval, and hearings began in the US and Canada on April 28, 2006, and May 11, 2006, respectively.

GAMES

PlayStation 2 software is distributed on CD-ROM and DVD-ROM; the two formats are differentiated by the color of their discs' bottoms, with CD-ROMs being blue and DVD-ROMs being silver. The PlayStation 2 offered some particularly high-profile exclusive games. Most main entries in the Grand Theft Auto, Final Fantasy, and Metal Gear Solid series were released exclusively for the console. Several prolific series got their start on the PlayStation 2, including God of War, Ratchet & Clank, Jak and Daxter, Devil May Cry, and Kingdom Hearts, Sly Cooper. Grand Theft Auto: San Andreas was the best-selling game on the console.

Game releases peaked in 2004, but declined with the release of the PlayStation 3 in 2006. The last new game for the console in Asia is Final Fantasy XI: Seekers of Adoulin, in North America is FIFA 13, and in Europe is Pro Evolution Soccer 2014. As of June 30, 2007, a total of 10,035 software titles have been released worldwide (counting games released in multiple regions as separate titles).







PlayStation 2 users had the option to play select games over the Internet, using a broadband Internet connection and a PlayStation 2 Network Adaptor. Instead of having a unified, subscription-based online service like Xbox Live as competitor Microsoft later chose for its Xbox console, online multiplayer functionality on the PlayStation 2 was the responsibility of the game publisher and ran on third-party servers. Most recent[when?] PlayStation 2 online games have been developed to exclusively support broadband Internet access. Xbox Live similarly requires a broadband Internet connection.

Sales

 The PlayStation 2 has sold over 150 million units worldwide as of March 31, 2012.[3][4] In Europe, it has sold 48 million units as of May 6, 2008, according to Sony Computer Entertainment Europe,[43] while in North America, it has sold 50 million units as of December 2008.[44] In Japan, the PS2 has sold 21,454,325 units as of October 1, 2008, according to Famitsu/Enterbrain.[45] In 2005, the PlayStation 2 became the fastest game console to reach 100 million units shipped, accomplishing the feat within 5 years and 9 months from its launch.
