Pop culture has gone to the birds, Angry Birds that is. The popular mobile device game from Finnish game maker Rovio has become a worldwide phenomenon. Rovio CEO Mikael Hed said in early December the paid version of the game had been downloaded over 12 million times, largely for iOS devices. On top of that, the free versions on iOS, Nokia, WebOS and Android were downloaded about 30 million times, Hed said. The franchise has expanded way beyond the original game that debuted in 2009. There are now several versions of the popular game and more to come this year. But Angry Birds isn't just about games there are also plush toys, fan-made items like Christmas ornaments and Halloween costumes, and there's even talk of an Angry Birds movie or TV Show. Here's a look at Angry Birds: the pop culture phenomenon.
