Yahoo buys more mobile expertise

Yahoo has bought another Silicon Valley mobile startup as CEO Marissa Mayer tries to create more compelling products for smartphones and tablet computers.

Tuesday’s acquisition of OnTheAir follows Yahoo’s recent purchase of a mobile startup called Stamped. In both cases, Yahoo was drawn more by the engineering talent working at the startups than the services that they have been offering.

Yahoo Inc., which is based in Sunnyvale, Calif., didn’t disclose how much it paid for OnTheAir, which is based in San Francisco.
