As 'Angry Birds' Maker Rovio Turns 10, What Comes Next?

This month marks the four-year anniversary of the release of "Angry Birds." Since then, the game’s developer has been flying high, and Rovio Entertainment has practically become a household name — at least, a topic of countless playground conversations.

But it wasn't always a smooth trajectory for the team based in Espoo, the second-largest city in Finland with a population of about 248,000. While it may seem as if Rovio was an overnight success with its mega-hit iPhone game featuring birds being flung across the screen, the company celebrated its 10th anniversary last week.
