The PlayStation 2 (officially abbreviated as PS2) is a home video game console developed and marketed by Sony Computer Entertainment. It was first released in Japan on March 4, 2000, in North America on October 26, 2000, and in Europe and Australia in November 2000, and is the successor to the PlayStation, as well as the second video game console in the PlayStation brand. As a sixth-generation console, the PS2 competed with Sega's Dreamcast, Nintendo's GameCube, and Microsoft's Xbox.

Announced in 1999, the PS2 offered backwards compatibility for its predecessor's DualShock controller, as well as its games. The PS2 is the best-selling video game console of all time, having sold 159 million units estimated by IGN, with 150 million confirmed by Sony in 2011. Over 3,800 game titles have been released for the PS2 since launch, with over 1.5 billion copies 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 PS2 remained popular well into the seventh generation, and continued to be produced until January 4, 2013, when Sony finally announced it had been discontinued after twelve years of production – one of the longest lifespans of 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 in Japan 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 Western launch. Despite the Dreamcast still received support through 2001, the PS2 remained as the only sixth generation console with an eye on the future for over 6 months before it would face competition from new rivals in the form of Nintendo's GameCube and Microsoft's Xbox. Many analysts predicted a close three-way matchup among the three consoles. The Xbox has 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. 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. 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. 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.

Software for the PlayStation 2 was distributed primarily on DVD-ROM, with a some titles being published on CD-ROM. In addition the console can play audio CDs and DVD movies, and is backwards compatible with almost all original PlayStation games. The PlayStation 2 also supports PlayStation memory cards and controllers, although original PlayStation memory cards will only work with original PlayStation games and the controllers may not support all functions (such as analog buttons) for PlayStation 2 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 2 USB ports, and 1 IEEE 1394 (Firewire) port (SCPH-10000 to 3900x only). 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.
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. 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.
Video and audioEdit
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.
PlayStation 2 users had the option to play select games over the Internet, using dial-up or a broadband Internet connection. The PlayStation 2 Network Adaptor was required for the original models, while the slim models included networking ports on the console. 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. Many games that supported online play exclusively supported broadband Internet access.
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 lawsuitEdit
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 US$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.
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, Kingdom Hearts, and 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 games for the console were Final Fantasy XI: Seekers of Adoulin in Asia, FIFA 13 in North America, and Pro Evolution Soccer 2014 in Europe. As of June 30, 2007, a total of 10,035 software titles had been released worldwide including games released in multiple regions as separate titles.
Initial reviews in 2000 of the PlayStation 2 acclaimed the console, with reviewers commending its hardware and graphics capabilities, its ability to play DVDs, and the system's backwards compatibility with games and hardware for the original PlayStation. Early points of criticism included the lack of online support at the time, its inclusion of only two controller ports, and the system's price at launch compared to the Dreamcast in 2000. PC Magazine in 2001 called the console "outstanding", praising its "noteworthy components" such as the Emotion Engine CPU, 32MB of RAM, support for IEEE 1394 (branded as "i.LINK" by Sony and "FireWire" by Apple), and the console's two USB ports while criticizing its "expensive" games and its support for only two controllers without the multitap accessory.
Later reviews, especially after the launch of the competing GameCube and Xbox systems, continued to praise the PlayStation 2's large game library and DVD playback, while routinely criticizing the PlayStation 2's lesser graphics performance compared to the newer systems and its rudimentary online service compared to Xbox Live. In 2002, CNET rated the console 7.3 out of 10, calling it a "safe bet" despite not being the "newest or most powerful", noting that the console "yields in-game graphics with more jagged edges". CNET also crticized the DVD playback functionality, claiming that the console's video quality was "passable" and that the playback controls were "rudimentary", recommending users to purchase a remote control. The console's two controller ports and expensiveness of its memory cards were also a point of critcism.
The slim model of the PlayStation 2 received positive reviews, especially for its incredibly small size and built-in networking. The slim console's requirement for a separate power adapter was often criticized while the top-loading disc drive was often noted as being far less likely to break compared to the tray-loading drive of the original model.
Demand for the PlayStation 2 remained strong throughout much of its lifespan, selling over 1.4 million units in Japan by March 31, 2000. Over 10.6 million units were sold worldwide by March 31, 2001. 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; this would remain unsurpassed until 14 years later when the PlayStation 4 reached 100 million shipments in 5 years and 7 months from its launch. By July 2009, the system had sold 138.8 million units worldwide, with 51 million of those units sold in PAL regions.
Overall, over 155 million PlayStation 2 units were sold worldwide by March 31, 2012, the year Sony officially stopped supplying updated sales numbers of the system.
The PlayStation 2's DualShock 2 controller is largely identical to the PlayStation's DualShock, with the same basic functionality. However, it includes analog pressure sensitivity on the face, shoulder and D-pad buttons, replacing the digital buttons of the original. (These buttons would later become digital again with the release of the DualShock 4.) Like its predecessor, the DualShock 2 controller has force feedback, or "vibration" functionality. It is lighter and includes two more levels of vibration.
Optional hardware includes additional DualShock or DualShock 2 controllers, a PS2 DVD remote control, an internal or external hard disk drive (HDD), a network adapter, horizontal and vertical stands, PlayStation or PS2 memory cards, the multitap for PlayStation or PS2, a USB motion camera (EyeToy), a USB keyboard and mouse, and a headset.
The original PS2 multitap (SCPH-10090) cannot be plugged into the newer slim models, as the multitap connects to the memory card slot as well as the controller slot and the memory card slot on the slimline is shallower. New slim-design multitaps (SCPH-70120) were manufactured for these models, however third-party adapters also exist to permit original multitaps to be used.
Early versions of the PS2 could be networked via an i.LINK port, though this had little game support and was dropped. Some third party manufacturers have created devices that allow disabled people to access the PS2 through ordinary switches, etc.
Some third-party companies, such as JoyTech, have produced LCD monitor and speaker attachments for the PS2, which attach to the back of the console. These allow users to play games without access to a television as long as there is access to mains electricity or a similar power source. These screens can fold down onto the PS2 in a similar fashion to laptop screens.
There are many accessories for musical games, such as dance pads for Dance Dance Revolution, In the Groove, and Pump It Up titles and High School Musical 3: Senior Year Dance. Konami microphones for use with the Karaoke Revolution games, dual microphones (sold with and used exclusively for SingStar games), various "guitar" controllers (for the Guitar Freaks series and Guitar Hero series), the drum set controller (sold in a box set (or by itself) with a "guitar" controller and a USB microphone (for use with Rock Band and Guitar Hero series, World Tour and newer), and a taiko drum controller for Taiko: Drum Master.
Specialized controllers include light guns (GunCon), fishing rod and reel controllers, a Dragon Quest VIII "slime" controller, a Final Fantasy X-2 "Tiny Bee" dual pistol controller, an Onimusha 3 katana controller, and a Resident Evil 4 chainsaw controller.
Mouse and KeyboardEdit
Unlike the PlayStation, which requires the use of an official Sony PlayStation Mouse to play mouse-compatible games, the few PS2 games with mouse support work with a standard USB mouse as well as a USB trackball. In addition, some of these games also support the usage of a USB keyboard for text input, game control (in lieu of a DualShock or DualShock 2 gamepad, in tandem with a USB mouse), or both.
Using homebrew programs, it is possible to play various audio and video file formats on a PS2. Homebrew programs can also be used to play patched backups of original PS2 DVD games on unmodified consoles, and to install retail discs to an installed hard drive on older models. Homebrew emulators of older computer and gaming systems have been developed for the PS2.
Sony released a Linux-based operating system, Linux for PlayStation 2, for the PS2 in a package that also includes a keyboard, mouse, Ethernet adapter and HDD. In Europe and Australia, the PS2 comes with a free Yabasic interpreter on the bundled demo disc. This allows users to create simple programs for the PS2. A port of the NetBSD project and BlackRhino GNU/Linux, an alternative Debian-based distribution, are also available for the PS2.
A successor, the PlayStation 3 was released in Japan and North America in November 2006 and Europe in March 2007.

The biggest difference between the Dual Shock 2 and the original… all of the buttons and even the digital pad offer analog support.
