Rovio Mobile's Angry Birds mobile game has been downloaded more than five million times by Android users.

"By end of year, we project earnings of over $1 million per month with the ad-supported version of Angry Birds", says developer Peter Vesterbacka.

As a comparison, it would take around 1.4 million monthly unit sales on iPhone's App Store to equal those revenues.

Vesterbacka also says that Angry Birds has now sold 12 million paid downloads on the App Store, out of a total of 30 million downloads across all platforms.
