Yahoo has bought another Silicon Valley mobile startup as CEO Marissa Mayer tries to create more compelling products for smartphones and tablet computers. The acquisition of OnTheAir follows Yahoo's recent purchase of mobile startup called Stamped. In both cases, Yahoo was drawn more by the engineering talent working at the start-ups than the services they have been offering.

OnTheAir enables users to hold online video chats in a talk-show format.
