Sony loses two key executives from its North American game team

Two key executives at Sony’s U.S. game business have left the company. And one of them, Rob Dyer, has joined social game maker Zynga to work on partnerships.

Scott Steinberg (pictured), vice president of marketing, has resigned. Dyer, who was senior vice president of publisher relations, also left recently, according to Industry Gamers. Steinberg evidently left without indicating his future plans.

Steinberg joined Sony in 2007 and served previously at Sega, Crystal Dynamics, Roxio, and Liquid Audio. Sony confirmed that Dyer had left to work at Zynga, where his title will be head of partner publishing. Dyer joined Sony in 2008 and previously was president of Eidos and Crystal Dynamics. No replacements have been named.

It’s not clear why the two executives left. Earlier this year, Peter Dille, another longtime marketing executive, resigned his position as senior vice president of marketing. He took a long break and resurfaced at Tapjoy. Guy Longworth was named to replace Dille in October. He previously worked at Procter & Gamble.
