When Sony released the PlayStation in the United States in 1995, its 32-bit processor was the most powerful available on the console market at the time.
Sony sold more than 70 million PlayStations worldwide by the time the PlayStation 2 was released in 2000.
The PlayStation 2 also sold very well in the U.S. and abroad. Sony released the PlayStation 3 in 2006, and it sold 80 million units to retailers by November 2013. The latest generation, the PlayStation 4, has been wildly successful thus-far, already selling 7 million units as of April.
