Gamasutra: I occasionally read someone write that "everyone plays video games now". I suppose this is to contrast with "the old days" when video gaming was unusual, and the players felt they were somehow exceptional.
But it's the long-time video game fans writing this stuff. Even now, "everyone plays video games" is not even close to true. The Entertainment Software Association's own 2009 promotional literature says 68% of US households play video games. That leaves 32% that don't. And that's in the US, still a relatively rich nation where people can "waste" money on game consoles and PCs-for-leisure.
Not so many years ago, it made sense to say "half the people in the world have never placed a phone call". They might have talked on the phone after someone else placed the call in some village out in the sticks. I suspect phones are much more common now, but game consoles and PCs are still expensive luxury devices in much of the world.
