Why CEO Don Mattrick is done at Zynga

It’s all over for Don Mattrick at FarmVille publisher Zynga.

The company announced today that its chief executive officer for nearly the last two years is leaving. Cofounder and former chief executive officer Mark Pincus is stepping back into the top role. This comes as Zynga, once the biggest name in all of social gaming, continues to struggle on mobile platforms, and that’s one of the big reasons that the publisher’s leadership isn’t shedding any tears about Mattrick’s exit. Worldwide revenues for gaming on iOS and Android could hit $30 billion this year, predicts market research firm Newzoo, and that’s money that Zynga just can’t find a way to grab.
