Yahoo (NSDQ: YHOO) plans to launch its Panama online ad platform for mobile devices in the first quarter of 2008, reports NMA (subscription required). Yahoo says it will allow advertisers to run integrated online and mobile campaigns, and control both from a single user interface. The company also says it wants to be the leading mobile internet advertising player, but it’s already lagging a few months behind Google, (NSDQ: GOOG) which launched AdSense for Mobile in September, as well as smaller independent players like AdMob. Still, the overall market is nascent enough that Yahoo’s delay may not represent too big a problem, so long as it can quickly ramp up and deliver high numbers of impressions to marketers.
