Closer to the end of 2010, Apple made rewind 2010 from iTunes store. The lists are Top Free (iPhone and iPad), Top Paid (iPhone and iPad) and Top Grossing (iPhone and iPad). And Angry Birds dominate all the list. In top paid app games, Angry Birds followed by Doodle Jump, Skee-Ball, Bejeweled 2 + Blitz, and Fruit Ninja. Angry Birds become a phenomenon when more than 30 millions donwloaded (free) and and had been sold for more than 12 millions copies Angry Birds. The game is about Angry birds who get angry, obviously and use a sling shot to launch themselves into the fortresses of the pigs, who steal their eggs.
Why this game is so famous? Why some peoples (12 millions) even buy this game? I have no idea.
