Angry Birds Space has been a runaway hit — so much so, in fact, that Rovio announced this morning on its Twitter account that the game has been downloaded over 100 million times. In April we reported that the game had eclipsed 50 million downloads just a month after being released, so it would seem that the rate of consumption has only slightly declined. The original Angry Birds has been downloaded over a billion times by now, and with things like Formula 1 sponsorships, the popularity of the Angry Birds Space franchise is showing no signs of easing up.
