"1 people out of every 14 on this planet will own a PlayStation."
How do you come up with that?
You are assuming that every Playstation branded device as a unique owner.
More than likely the vast majority of PSX owners bought a PS2 and then a PS3 and maybe a PSP or Vita. Since the PS3 hasn't sold as much as the PS2 It's also likely that most of the PS3 owners are also PS2 owners. If there are 400 million Playstation branded devices out there, and the PS2 sold a lifetime of 154 million, I'd estimate there have been around 200 to 250 million PS owners between 1995 and 2012. Therefore I would estimate on, the high end, 250m out of 7b which would be about 1 out of every 28 people.
That's impressive, however I'd say it's still very inflated.
Now if you figure in Nintendo, Atari, PC, Xbox, Mobile, Browser, etc it's very possible that more people play games than not.
