Mobile app downloads account for $26 billion in revenues, and companies are clamoring to be a part of this windfall.

Of course, with both Google (GOOG 0.07%)(GOOGL 0.08%) and Apple (AAPL +0.59%) being the largest recipients of app store dollars, the report is important reading for investors in both companies.
