Android Becoming a Factor in U.S. Mobile Ad Market

Android smartphones are becoming a bigger factor in the U.S. mobile advertising market, with ad requests growing 97 percent in just two months between October 2009 and December 2009, according to AdMob.

Of those one billion ad requests tracked by AdMob, 90 percent were from U.S.-based devices.AdMob tracks handset and operator data from every ad request in its advertising network of more than 15,000 mobile web sites and applications.

Much of the growth was driven by the release of the Motorola Droid. Before the Droid’s launch, HTC devices accounted for 98 percent of Android requests. In December, that fell to 56 percent, with 39 percent from Motorola (which also offers the CLIQ) and five percent from Samsung.

The Motorola Droid already is the leading Android handset in the AdMob network and generated 30 percent of requests in December.
