Rovio has today announced that their Angry Birds series of games has reached the half billion downloads plateau; to emphasize this number, that’s 500,000,000 downloads. The popular bird, pig, and slingshot series of games consists of Angry Birds and its Season- and Rio-flavored counterparts. Rovio should be extremely proud for reaching this milestone, as Angry Birds has become the best-selling mobile game ever. Rovio has also done exceptionally well with their Angry Birds merchandise, bringing in over $100 million in revenue in the first year.
