iPhone and Android mega-hit Angry Birds has now been downloaded 250 million times across all versions and platforms. The figure, confirmed by Rovio founder Peter Vestebacka to TechCrunch, means that the franchise has seen 50 million downloads in the last four weeks, since the company revealed last month that it had seen 200 million total downloads. Only three months ago, Rovio said that the franchise had seen 100 million downloads overall. The original Angry Birds was among the top selling iOS apps in 2010, and led first day sales on Apple's Mac app store in January. Rovio is currently working on a location-based platform for the series called Angry Birds Magic, which will eventually be built into all Angry Birds titles. After receiving $42 million in funding earlier this year, Rovio chairman Kaj Hed said the company was aiming for an initial public offering of stock sometime in the next five years.
