Electronic Arts (NSDQ: ERTS) has agreed to a five-year deal with Facebook to use Facebook’s Facebook Credits virtual currency system exclusively in its games on the social network. By signing up Electronic Arts, which jumped into the social games market last fall when it purchasedPlayfish, Facebook will now have exclusive deals with four of the top ten Facebook developers, including Zynga, RockYou, and CrowdStar. Electronic Arts, which is behind games like PetSociety and Restaurant City is the number four developer on the social network, according to AppData.
The deals, all of which have been reached since May, come as Facebook has begun to push for the widespread adoption of Credits, which promise to provide a large non-advertising revenue stream for the company, since it takes a 30 percent cut of Credits sales. In September, Facebook even began to sell its virtual currency system at brick-and-mortar stores, announcing that Target would sell gift cards nationwide that customers could redeem for Credits.
