but don't forget Google makes a lot of cash from advertising on free apps. They own Admob and Google Mobile Ads so have a good chunk of the Android advertising market. If an app gets purchased Google makes 30% of the sale, but with advertising they make between 15-35% for the lifetime of the app. Whats that worth? about a billion a year or so... http://www.mobilemarketer.com/cms/news/advertising/7772.html http://www.mobilemarketer.com/cms/news/advertising/7772.html
