The PlayStation 2 (often abbreviated as PS2) is a home video‑game console developed and marketed by Sony Interactive Entertainment. Released in March 2000 in Japan and later that year worldwide, it is the successor to the original PlayStation and the second entry in the PlayStation series. The PS2 is notable for being the best‑selling console of all time, with over 155 million units shipped, and for its extensive library of more than 4,000 game titles, compatibility with PlayStation 1 software, and integrated DVD‑playback capability, which helped popularize the DVD format.
History
- Development: Initiated shortly after the launch of the PlayStation in 1994, the PS2 project (codenamed "PlayStation 2" and later "Project M") aimed to improve graphics performance and media functionality. The console was unveiled at the 1999 E3 conference.
- Launch: Released on 4 March 2000 in Japan, 26 October 2000 in North America, and 24 November 2000 in Europe.
- Lifecycle: Production continued until 4 January 2013, making it one of the longest‑running consoles in history. The final model, the "PS2 Slim", ceased manufacturing in 2013, though the system remained supported with new games until late 2013.
