Cumulative app revenue to hit $30 billion by the end of 20121
Apple App Store. ABI says that the original Android Market has matured into the Google Play Store, which has a 33% market share of money spent on apps, estimates the researcher, but still trails the App Store. The key battle for third is between Microsoft and RIM says ABI. Both have made it easy for developers to turn their ideas into apps and from apps into money. Should Windows Phone 8 and/or BlackBerry 10 hit it big, it won't be too hard for developer's to share in the success of either platform with the Windows Phone Marketplace and BlackBerry App World.
