PlayStation 2

The development of the PlayStation 2 was first announced in March 1999, and while it would not be released until 2000, the announcement was enough to slow the momentum for the Sega Dreamcast's North American launch, despite the Dreamcast having a head start over that generation 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 one thousand dollars for a PS2. 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.
Although Sega announced the discontinuation of the Dreamcast in March 2001, the PS2 would face competition from newer rivals; Microsoft's Xbox and the Nintendo GameCube. Many analysts predicted a close three-way matchup between the three consoles; the Xbox having the most powerful hardware, while the GameCube was least expensive console and Nintendo changed its policy to encourage third-party developers, and while the PlayStation 2 theoretically had the weakest specs 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.
PlayStation 2 software is distributed on CD-ROM  and DVD-ROM In addition the console can play audio CDs and DVD movies, and is backwardly compatible with PlayStation games. The PS2 also supports PlayStation memory cards and controllers, although PS1 memory cards only work with PS1 games and the controllers may not support all functions (such as analog buttons) for PS2 games.
