Mobile advertising proved that it was still nascent at today's Under the Radar - Mobility conference in Mountain View.

Keep an eye on Zoove and Transpera as potential game-changers in the mobile advertising market. (Disclosure note: Transpera is a First Round Capital investee.) Here's a quick sketch of the presenters and their game plans.
