Facebook Inc. and Zynga Game Network Inc. ended weeks of tense negotiations by agreeing Tuesday to a five-year deal to keep Zynga's social games on the social network.
The agreement between the Bay Area companies officially puts an end to a high-stakes game of corporate poker, one that involved tens of millions of dollars.
At issue is a virtual currency Facebook wants all developers on its platform to use in any online commerce, with Facebook taking a cut of all sales. Zynga — which created Farmville, Mafia Wars and several of the most popular apps on Facebook — threatened to start taking its games elsewhere.
In a joint statement, Zynga's chief executive, Mark Pincus, and Facebook's chief operating officer, Sheryl Sandberg, said Zynga is "testing Facebook Credits in select games and will expand to more titles over the coming months."
