Patent WO1999040983: PORTABLE ELECTRONIC DEVICE AND ENTERTAINMENT SYSTEM [pdf, source] (PocketStation patent)
The PlayStation, officially abbreviated as PS, at the time referred to as PSX (not to be confused with the PSX console) and also known as PS1 is a 32-bitvideo game console first released by Sony Computer Entertainment in Japan on December 3, 1994, with Western releases in September 1995. The PlayStation was the first of the PlayStation series of consoles and handheld game devices. As part of the fifth-generation of gaming, it primarily competed with the Nintendo 64 and the Sega Saturn. In 2000, a re-designed, "slim" version was released, called the PSone, replacing the original grey console, and also being renamed to avoid confusion with its successor, the PlayStation.
