The PlayStation was the first of the PlayStation series of consoles and handheld game devices. 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 newly-released PlayStation 2.

The PlayStation was the first "computer entertainment platform" to ship 100 million units, which it had reached 9 years and 6 months after its initial launch.
