Does playing Angry Birds really rouse your appetite for eggs?

If so, you'll like Rovio's latest plan: the company behind Angry Birds has decided to self-publish a family cookbook filled with egg recipes, both as a book and as an app.  The popular game, which features furious red fowl catapulting themselves at dastardly green swine, just hit the 200 million download mark. 

While it seems like a peculiar gambit, the huge success of Angry Birds, not just as a game, but spun out into numerous different franchises, makes it entirely possible that such a cookbook could garner significant sales. The company sells t-shirts, toys, keychains, and other accessories, and will soon have its own animated TV series and board game.

The move marks Rovio's bid to bring Angry Birds from being just a mobile game to being an entertainment brand.
