Successors

Sony's successor to the PlayStation is the PlayStation 2, which is backwards compatible with its predecessor in that it can play almost every PlayStation game. Unlike emulators that run on a PC, the PlayStation 2 actually contains the original PlayStation processor, allowing games to run exactly as they do on the PlayStation. For PlayStation 2 games this processor, called the IOP, is used for input and output (memory cards, DVD drive, network, and hard drive). Like its predecessor, the PlayStation 2 is based on hardware developed by Sony itself.

The third generation of the PlayStation known as the PlayStation 3 (abbreviated PS3), was launched on November 11, 2006 in Japan, November 17, 2006 in North America, and March 23, 2007 in Europe. The PlayStation 3 was initially backward compatible with all games that were originally made for the PlayStation and PlayStation 2, but due to the removal of the PlayStation 2 Emotion Engine Chip after the introduction of the 40 GB version, the capability to play PlayStation 2 discs is limited now to software emulation, and the capability to play original PlayStation games is still possible. While PS3 games are not region-locked, PlayStation and PlayStation 2 games still only play on a PS3 console from the same territory. The redesigned "Slim" form factor PS3 introduced in 2009 has had the ability to play PlayStation 2 games entirely removed, though it can still play games from the original PlayStation.

The PlayStation Portable (abbreviated PSP) is a handheld game console first released in late 2004. The PSP is capable of playing PlayStation games downloaded via Sony's online store, and can also play any PlayStation game by using the PlayStation 3's remote play feature while the disc in the PlayStation 3. Sony hopes to release nearly all PlayStation games on a gradual basis. It is also possible to convert original PlayStation disc images into executable binaries using freely available software. These games are then playable on PSPs that have been modified to run unsigned code.

Launch

The PlayStation was launched in Japan on December 3, 1994, North America on September 9, 1995, Europe on September 29, 1995, and Oceania in November 15, 1995. The launch price in the American market was US$299 (a price point later used by its successor, the PlayStation 2), and Sony enjoyed a very successful launch with titles of almost every genre, including Battle Arena Toshinden, Warhawk, Air Combat, and Philosoma, and Ridge Racer. Almost all of Sony's and Namco's launch titles went on to spawn numerous sequels.
