Yahoo! reports that video games nearly doubled the revenue of Hollywood box office returns. I've heard reports that Halo 3 alone sold more than 4 million copies, and that's after a later 2007 quarter release. Imagine Halo 3's yearly profit returns if it had come out in the spring or summer.
This is a huge story, mainly because it marks a critical watershed moment for video gaming. If gaming continues to outsell the movie industry (and there's no reason to think it won't), the gaming industry as a whole will begin to earn some overdue respect, both from the rest of the entertainment industry and the general public. I think the broad perception out there is that gaming is just for little kids or maladjusted, anti-social adults. That may have been true fifteen or twenty years ago, but no longer.
