The PlayStation (often known as the PS1 or the PSX) is a video game console made by Sony released in December 1994. At the time, it was competing against the Nintendo 64 and the Sega Saturn. PlayStation games were stored on CDs. The controllers that were first released with the console had no analog joysticks on them, but analog joysticks and a vibration feature were added to later controllers. A slimmer version of the console called the PSOne was released in 2000. It was white instead of grey. It was succeeded by the PlayStation 2 in March 2000 and was discontinued on March 23, 2006 (eight months before the PlayStation 3 was released).
