Yahoo! slurps! teeny! video! chat! upstart!

Yahoo! has acquired tiny video chat firm OnTheAir, which will join the web firm's mobile division.

The web giant's new chief Marissa Mayer made mobile a priority for reviving her company's flagging fortunes; the firm has already bought Stamped, a mobile startup that lets folks share information about restaurants and music on their phones.

OnTheAir is a five-person outfit that does video chat and video presentations. With OnTheAir, one person can MC a presentation and then invite speakers to present one by one, queuing them up and then displaying them next to the MC.

There's no word yet on whether Yahoo! will continue OnTheAir's usual services or not. The terms of the deal haven't been disclosed.

"While we haven’t yet attained our dream of building a widespread daily use product, we are just as committed to it. And this is why we’re so excited to be joining Yahoo!," OnTheAir stated on its website.

"When we first met the team at Yahoo!, it was clear that everybody there is committed to making mobile products the backbone for the world’s daily habits. All in all, it’s a fascinating time to be joining Yahoo!"

Yahoo! has suffered at the hands of Google and other rivals, and hasn't had any major brainwaves for mobile internet yet. Mayer said she wants to the firm to concentrate on smartphones and tablets, with at least half of Yahooers working on mobile products. ®
