Tech titans Google, Facebook, Apple and others are in heated contention for ad sales, web traffic, and other business. 

Obama toasts Jobs, Zuckerberg, other tech titans

"President Barack Obama sat down with none other than Steve Jobs, Mark Zuckerberg, Eric Schmidt, Oracle's Larry Ellison, Yahoo's Carol Bartz and a handful of other billionaire tech titans.

According to the the New York Times political blog, The Caucus, the remaining folks in the shot are: Cisco's John Chambers, Twitter's Dick Costolo, Netflix's Reed Hastings, Stanford University president John Hennessy, Genentech's Art Levinson and "cleantech" entrepreneur Steve Westly."
