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 +0.10%)(GOOGL +0.07%) and Apple (AAPL 0.06%) being the largest recipients of app store dollars, the report is important reading for investors in both companies.
