The Angry birds series has been undeniably successful. Starting with its debut on iOS devices and eventual ports into other platforms, the franchise has proved extremely popular. At one point, the Playstation 3 version of Angry Birds even became the best selling game on PSN. The company announced 1 billion downloads for Angry Birds in May. The download count, however, includes all platforms and all the Angry Birds games that Rovio has made, which are: Angry Birds, Angry Birds Seasons, Angry Birds Rio and Angry Birds Space, as well as the free, light versions of the games.
