Don Mattrick has been appointed CEO of Zynga, effective Monday, July 8, the social games firm has confirmed.
Mattrick leaves Microsoft after six years at the company, overseeing Xbox as the president of its Interactive Entertainment Business.
He previously served as the president of worldwide studios at EA.
"Don is unique in the game business," said Zynga founder and chairman Mark Pincus. "He can execute in multiple domains -- hardware, software and network, and he's been the person responsible for game franchises like 'Need for Speed,' 'FIFA' and 'The Sims.'
"He's one of the top executives in the overall entertainment business and he's a great coach who has inspired people to do their best work and build strong, productive teams. He deeply understands the value of a network and the importance of creating lifelong consumer relationships.
"He turned Xbox into the world's largest console-gaming network, growing its installed base from 10 to 80 million and transformed that business from deep losses to substantial profits. And he has grown the Xbox Live player network from 6 to 50 million active members in 41 countries."
Pincus steps down from the position of CEO, but will continue to serve in his role as chairman and chief product officer.
"I'm excited to partner with Don and the rest of our team to return Zynga to its leadership role in inventing and growing Play as a core human experience," he added.
Mattrick's exit from Microsoft comes just months before the company's next-generation console, Xbox One, hits store shelves this November.
In an email to employees, Microsoft CEO Steve Ballmer thanked Mattrick "for setting us on a path to completely redefine the entertainment industry".
"This is a great opportunity for Don, and I wish him success," he said.
"Don’s directs will report to me and will continue to drive the day-to-day business as a team, particularly focused on shipping Xbox One this holiday.
"Since joining IEB more than six years ago, Don and his team have accomplished much. Xbox Live members grew from 6 million to 48 million. Xbox 360 became the No. 1 selling console in North America the past two years. We introduced Kinect and have sold more than 24 million sensors. We released fantastic games, and, most importantly, we expanded Xbox to go beyond great gaming to deliver all the entertainment people want — sports, music, movies, live television and much more.
"In the past month, the IEB team showed for the first time here on our Redmond campus, and again at E3, how we are going to continue to transform entertainment with Xbox One. I am incredibly proud of the work and vision culminating in Xbox One.
"I’m particularly excited about how Xbox pushes forward our devices and services transformation by bringing together the best of Microsoft. The consoles are incredible all-in-one devices with built-in services that consumers love, including Bing, Xbox Live, Internet Explorer, SkyDrive and Skype. And, just as important, Xbox Games, Xbox Video, Xbox Music and SmartGlass light up Windows PCs, tablets and phones.
"Thank you, Don, for setting us on a path to completely redefine the entertainment industry. The strong leadership team at IEB and their teams are well positioned to deliver the next-generation entertainment console, as well as transformative entertainment experiences, long into the future."
