Photos: Cruise, Degeneres save Yahoo demo

Gremlins did in the Yahoo Go TV demo during Semel's keynote speech at the Consumer Electronics Show on Friday, putting the Yahoo CEO and fellow executives in a bind. Semel put an end to the ad libbing by calling Hollywood star Tom Cruise on stage to entertain the crowd. "I guess if you're going to have a demo glitch (there is no) better way to follow it up than with Tom Cruise," Semel said.
