So Angry Birds Space came out last week for iOS, Android, Mac, and PC. According to developer Rovio, the game sold over 10 million downloads across all platforms in less than three days.

That may seem like an absurd number, but let's keep things in perspective: To date, the first three Angry Birds games sold more than half a billion copies. That's billion, folks. Billion with a B.

That may 10 million look like a drop in the bucket, but it's only been three days. Who knows how many people will buy it by the end of the month?
