Google said that there has now been 10 billion downloads made from Android Market, from its launch late in 2008. According to Eric Chu from the Android Developer Ecosystem, the store is now seeing one billion downloads made per month.

While Apple and Google have largely announced different milestones for the App Store and Android Market, there are points of overlap which show the speed with which each has developed.

It took Apple nine months to grow from one billion to three billion downloads (from April 2009 to January 2010), the same time as for Android Market (June 2010 to March 2011). However, it then took Apple one year to get from three million to ten million (January 2010 to January 2011), compared with nine months for Android (March 2011 to December 2011).

To mark the event, Google is holding a promotion where for 10 days, a number of premium apps are being made available for US$0.10.  The list includes Asphalt 6 HD, Color & Draw for Kids, Endomondo Sports Tracker Pro, Fieldrunners HD, Great Little War Game, Minecraft, Paper Camera, Sketchbook Mobile, Soundhound Infinity and Swiftkey X.

In July 2011, Apple said that it had passed the 15 billion download mark from its App Store, two-and-a-half years after launch.
