At first I brushed this off as pretty ridiculous, but when I sat down and actually looked at the numbers, it started to make sense. When you look at sales numbers for each title (or series, in SMB's case), Rovio, developer of Angry Birds, reported 350 million downloads since December 2009. That number was reported in September of this year, so you know from there that the number is climbing steadily. This also includes different versions, including the free Angry Birds Lite download."
