BlackBerry leads smartphone ad requests

New stats from AdMob reveal smartphone share of mobile ad requests.

RIM’s BlackBerry 8100 smartphone had the greatest share of worldwide ad requests from smartphones in February at 34 per cent, according to AdMob.

Nokia’s smartphones followed in second with a 29 per cent share of ad requests, while Motorola’s Smartphones came in last with just one per cent.

In the US, iPhone traffic flattened slightly during the month of February. AdMob says this is consistent with the theory that people use new devices a great deal in January, only to have traffic slow down in the following months.
