Zynga lets wannabe mob bosses, farmers, and poker champs get their game on. The company is a leading social game developer with titles such as Mafia Wars, FarmVille, Café World, and Zynga Poker. It offers the games online for free through social networking sites Facebook, Myspace, and Yahoo!. They can also be downloaded onto Apple's iPhones and myriad mobile devices based on Google's Android platform. The company makes money by selling advertising consisting of branded virtual goods, sponsorships, and engagement ads via credit card and PayPal to users within the games. Zynga is owned by CEO Mark Pincus, who founded the company in 2007 and named it after his late dog Zinga. The company filed for an IPO in 2011.
