Angry Birds‘ developer Rovio is betting everything it has on the franchise, and will be expanding it rather than looking towards new IPs.

“We are betting everything on Angry Birds,” Rovio head Peter Vesterbacka said, according to VentureBeat. “We want to be the first entertainment brand with a billion fans. That will take us two or three years to do. Next year, we want to be the leading entertainment brand in China.”

The developer is pushing out into China in an attempt to reach out to the fans there, and they hope that Angry Birds can become a worldwide entertainment brand. In order to keep the brand going, Rovio will be taking inspiration from Nintendo and following the Mario route of endless spin-offs. I bet you can’t wait for Angry Birds Tennis.

Rovio’s strategy of putting all their bird eggs in one angry basket is probably the safe one when you consider they already have 250million downloads and scooped the coveted Grand Prix award at the Develop Awards last night.
