Speaking at the Game Developers Conference in San Francisco this week, Rovio Mobile’s Peter Vesterbacka let it be known that his company’s wildly successful mobile game — Angry Birds — is quite popular amongst Android users. How popular you ask? The free, ad-supported version of the bird-flinging, pig pulverizing title has been downloaded over 30 million times. We would be interested to know how many ad impressions, and how much cash, Angry Birds generates every month. Congrats to Mr. Versterbacka and the Rovio team, your distain for swine has finally paid off.
