It had taken Google nearly three years to reach 10 billion downloads and less than a year to exceed that by 150%.Every day, nearly 1.3 million Android smartphones are activated somewhere on Earth. In September, Google said it’s mobile operating system was on 500 million smartphones. In contrast, Apple announced 400 million iPhone activations (not counting iPad and iPod Touch) at its iPhone 5 launch earlier this month.Apple is still ahead of Google in the app-volume race but Android has closed the gap. There were 700,000 apps in Apple’s App Store as of the iPhone 5 announcement. Android has 675,000, the closest that it has come to matching iOS app numbers. As of Apple’s World Wide Developer Conference in June, iOS users had downloaded nearly 30 billion apps, so, Android has some catching up to do.When Google announced 10 billion Android downloads, it celebrated with 10 days of apps for 10 cents. Google will do much the same this time around but expand the deals to all of the content found in Google Play, apps, movies, books and music.
