Rovio has announced that 6.5 million people downloaded Angry Birds to their smartphones on Christmas Day, double the number of phone activations estimated to have occurred over the holidays. “We’re really excited to have such a massive number of new people get acquainted with Angry Birds over the holidays — we have exciting new releases lined up for 2012, and can’t wait to introduce them to the public,” Rovio’s Ville Heijari told AllThingsD. The figure represents all three versions of the game: Angry Birds, Angry Birds Seasons and Angry Birds Rio, in both paid and free downloads. The number of downloads for the game is up over Christmas 2010, when 2 million people acquired the game on both iOS and Android devices. Thanks, Joystiq.
