Angry Birds Space does 20 million downloads in first week

Having broken iTunes when it launched, and managed 10 million paid downloads in under three days, Angry Birds Space continues to generated headlines.

According to CMO Peter Vesterbacka, the game has now done more than 20 million downloads - on iOS, Android and PC/Mac - in its first week.

"A great start" he tweeted.

Of course, it's got plenty of catching up in terms of reaching the more than 150 million downloads each of the first three games have done.

No doubt the release of a free-to-play version will aid that; plus the Windows Phone 7 version, of course.
