"The game industry earns more money per year than Hollywood."
This is one of my major pet peeves. It's one of those pieces of information that is passed around as common knowledge, is quoted frequently in the press (usually in the non-gaming press, but still maddingly often in gaming publications, who really should know better), and has been used to justify everything from a game's legitimacy as an art form to higher salaries for voice actors. The thing is, it's not true. Not even close, actually.
I was going to write a whole post tearing the assumption apart, but it seems GrumpyGamer beat me to it by two years. They have a very entertaining and thorough post about it here.
So please, next time you hear someone perpetuating this silly notion, hit them. Hard and fast.
