It competes primarily with Electronic Arts ( EA), Playdom which was recently acquired by Disney ( DIS) and other independent social gaming studios. Although Zynga is present on multiple social and mobile platforms, most of its revenue is generated through Facebook, the largest social network in the world with over 800 million users. Zynga announced last year that it would launch its own platform, Zynga Direct, to host its games enabling users to play directly on its platform. It recently unveiled the Zynga Platform and zCloud, its own cloud infrastructure platform for social game developers.
