Mobile app downloads account for $26 billion in revenues, and companies are clamoring to be a part of this windfall. The recent report "App Annie Index: Q2 2014" analyzes the industry, where freemium and advertising dominate, and many an interesting nugget can be mined from this paper. Of course, with both Google (NASDAQ:GOOG)(NASDAQ:GOOGL) and Apple (NASDAQ:AAPL) being the largest recipients of app store dollars, the report is important reading for investors in both companies. 

 
In the This Week in Tech video below, The Motley Fool's general manager and senior tech analyst, Eric Bleeker, and tech bureau chief, Max Macaluso, break down what they learned in the App Annie/IDC report, such as the fact that Japan, U.S., and China account for half of Apple's iOS app store sales, Brazil is seeing surging Google Play store downloads, and that freemium revenues grew 211% in 2013 vs. 56% for in-app advertising.
