Few mobile software titles see the success that Rovio’s Angry Birds has seen, and the ad-supported free version for Android has seen over 7 million downloads already. With in-app purchase power called Bad Piggy Bank on the way, Rovio should be raking in the dough. If virtual must-have accessories don’t do the trick for you (pig scarves?), perhaps an ad-free premium version will draw you into Rovio’s carrier billing plan. Even if you never spend a dime on Angry Birds, Rovio will be pocketing some serious change, thanks to those ad banners. But that’s not the end of it.

Rovio now has AdMob’s pre-roll (or play) videos queued up, as seen in the Android and Me video below. Peter Vesterbacka’s claim that Rovio will be making a million a month by the end of the year is starting to come into focus.
