In the immediate wake of our report on Google mobile ad revenues, TechCrunch reports today that the search giant saw a 2x year-over-year increase in mobile search ad requests (the largest source of its mobile ad revenues) in 2011.

Click-to-call also continues to grow since we first covered its introduction two years ago. Specifically, Chatterjee now reports more than half a million active advertisers and 10 million calls per month for click-to-call ads.
