The smartphone game Angry Birds has become incredibly popular with 50 million downloads occurring in just one year. In the game you shoot birds at pigs using slingshots while the pigs try to protect themselves. The Finnish company Rovio invented it. In fact, the firm was the first to develop and release video games as an app for mobile phones. Up to now it has invented more than 50 such games.
