The NPD Group (those same people who bring us all the neat sales numbers) just published their annual results charting how much of the US actually plays video games. And yeah, we already gave away the punchline in the headline.
72% of Americans play some sort of video games (that's up from 64% last year). Of that 72%, only 42% play games online (that's up from 40% last year). And of that 42% of online players, 90% play online with their PC. Also of note, 50% of online console gaming was on the Xbox 360. And only 2-3% of NPD's respondents reported owning more than one console. How's that for some late afternoon watercooler fodder?
