Unfortunatley, they dont count digital distribution. Adding that would mean we've already passed the movie industry. Huraah for cumulative interest!
Hey! Your right!

It has been added to the front page.

This was inevitable, I'm glad it finally became a reality!
Yeah, oh and thanks.

EDIT: What's interesting, is that this doesn't include hardware sales, just software sales. So when you think about it, there is even more money in it, and also, all those people who just got Wiis for Wii sports aren't included in this either, as Wii Sports is free.
Honestly, I think Hollywood deserves to get their ass handed to them by the games industry. All the overpayed actors who are ruining their lives for NO reason, and complaining about EVERYTHING need to get a f**king wake-up call.
Also, I hope this hits home for them, and makes movie companies start making actual good movies. Over the last few years, the quantity of good movies per year has gone down quite a bit. But at the same time, the quantity of of good games per year has gone up, mostly from big companies getting a clue, and realizing that better games make them more money.
