The PlayStation (known early in development as the PlayStation EXperimental, or PSX) was Sony's first video-game console and it was launched in 1994. The system was widely popular and quickly became the best selling home console to date, only to be passed by its successor, the PlayStation 2.

It was initially set to be an add-on for Nintendo's Super Nintendo Entertainment System as an answer to Sega's Sega CD. When the prospect of releasing the system as an add-on dissolved, Sony transformed it into the PlayStation video game console. Ironically the game system that was supposed to help Nintendo hindered them instead since the Final Fantasy games from VII onwards were released on the Sony platform instead of the successor of the Super Nintendo Entertainment System, the Nintendo 64 due to space restraints and other technological hindrances.

The PSone (also PSone, or PS1) was a smaller and redesigned version, released in 2000. Sony also released a small LCD screen and an adapter to power the unit for use in cars. The PSone is fully compatible with all PlayStation software.
