iOS App Store downloads have surpassed the 40 billion mark, Apple has announced. The company adds that almost 20 billion of those happened in 2012 alone, and that there are now over 775,000 titles in the App Store. More than 300,000 are iPad-native. So far, developers have been paid over $7 billion in their share of app revenue. Apple claims a 30 percent cut from any App Store sale, which suggests that Apple has pulled in $3 billion from the business.
