Developers Rovio may be giving Angry Birds away for free, but that doesn’t mean the team isn’t making any money on the game. Speaking at LeWeb 2010 today, Rovio CEO┬áMikael Hed revealed that the adverts on the Android version of Angry Birds is pulling in $1m per month.

That’s actually more than the premium version of Angry Birds on sale in Apple’s App Store, which is a paid-app rather than ad supported.
