The PlayStation[note 1] (officially abbreviated to PS, and commonly known as the PS1 or its codename, PSX) is a home video game console developed and marketed by Sony Computer Entertainment. The console was released on 3 December 1994 in Japan,[2] 9 September 1995 in North America, 29 September 1995 in Europe, and 15 November 1995 in Australia. The console was the first of the PlayStation lineup of home video game consoles. It primarily competed with the Nintendo 64 and the Sega Saturn as part of the fifth generation of video game consoles.

The PlayStation is the first "computer entertainment platform" to ship 100 million units, which it had reached 9 years and 6 months after its initial launch.[9] In July 2000, a redesigned, slim version called the PS one was released, replacing the original grey console and named appropriately to avoid confusion with its successor, the PlayStation 2.

The PlayStation 2, which is backwards compatible with the PlayStation's DualShock controller and games, was announced in 1999 and launched in 2000. 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 11 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 11 years after it had been released, and less than a year before the debut of the PlayStation 3.[6]

On 19 September 2018, Sony unveiled the PlayStation Classic, to mark the 24th anniversary of the original console. The new console is a miniature recreation of the original PlayStation, preloaded with 20 titles released on the original console, and was released on 3 December 2018, the exact date the console was released in Japan in 1994.[10]
