The PlayStation brand today marks its 25th anniversary — the original Japanese console launched on December 3, 1994. Since then the consoles have swept the market, shooting to the top of the list of most consoles sold, and playing hosts to some of the best games ever made.

The original console was a success right from the word go, selling 100,000 units on launch day. It was part of the fifth gen console line-up, ushering in the era of 3D graphics and disc-based games. While the Nintendo 64 and the Sega Saturn gave it some pretty stiff competition, the PS1 ultimately sold more than both of them combined. Since then the consoles have cleaned house, both in terms of consoles sold and games produced.
