Sony releases sales information every year and ZhugeEX from NeoGAF took the time to look through data from many fiscal year reports. ZhugeEX found that since December 1994, Sony has sold more than 370 million PlayStation consoles. Those sales come from the PS1, PS2, PS3, and PS4.
ZhugeEX was able to show just how successful Sony has been in the console gaming world over the past 20 years.
Here is how the consoles sold:
PlayStation 1 - 102 Million
PlayStation 2 - 155 Million
PlayStation 3 - 87 Million
PlayStation 4 - 20 Million
