How Much Do Blizzard Contribute To Activision's Bottom Line?

Activision and Blizzard, they're now tight, combining Guitar Hero and Call of Duty's dollars with those World of Warcraft rakes in on a monthly basis. But what's the split between the two?

Activision's freshly-released annual report lets us know (using net revenue as a yardstick).

And the winner is...Activision, who for 2008 (and we're talking calendar 2008 here) raked in $2.1 billion. Blizzard, meanwhile, could "only" pull in $1.3 billion (with 97% of that income derived from World of Warcraft subscriptions). So it's Activision that are top dogs. But that's coming off a year in which Guitar Hero really exploded into the mainstream, and which saw not only the release of Call of Duty: World at War, but also the majority of Call of Duty 4's sales.

The year before that? Blizzard again cracked the billion mark, earning $1.1 billion, while Activision made a net revenue of only $272 million. No wonder Blizzard's books looked so good.
