Steven Anthony "Steve" Ballmer is an American businessman who currently serves as the CEO of Microsoft, having held that post since January 2000.
Steve Ballmer joined Microsoft on June 11, 1980, and became Microsoft's 30th employee, the first business manager hired by Gates.
In 2009, and for the first time since Bill Gates left Microsoft as full-time chairman, Ballmer made the opening keynote at CES.
In May 2012, hedge fund manager David Einhorn called on Ballmer to step down as CEO of Microsoft. "His continued presence is the biggest overhang on Microsoft's stock," Einhorn said in reference to Ballmer.
In a May 2012 column in Forbes magazine, Adam Hartung described Ballmer as "the worst CEO of a large publicly traded American company", saying he had "steered Microsoft out of some of the fastest growing and most lucrative tech markets (mobile music, handsets and tablets)".
On June 19, 2012 Ballmer revealed Microsoft's new tablet device called Microsoft Surface at an event held in Hollywood, Los Angeles.
Ballmer has also served as director of Accenture Ltd. and a general partner of Accenture SCA since October 2001.
