The PlayStation (officially abbreviated PS, commonly known as the PS1 or its codename PSX) is a home video game console developed and marketed by Sony Computer Entertainment. It was first released on 3 December 1994 in Japan, on 9 September 1995 in North America, on 29 September 1995 in Europe, and on 15 November 1995 in Australia, and was the first of the PlayStation lineup of video game consoles. As a fifth generation console, the PlayStation primarily competed with the Nintendo 64 and the Sega Saturn.
The last PS one units were sold in late 2006 to early 2007 shortly after it was officially discontinued, for a total of 102 million units shipped since its launch eleven years earlier. Games for the PlayStation continued to sell until Sony ceased production of both the PlayStation and PlayStation games on 23 March 2006 – over eleven years after it had been released, and less than a year before the debut of the PlayStation 3.
