Google said that it passed the 11 billion Android Market app download mark in the fourth quarter of 2011, having trumpeted reaching the 10 billion mark earlier in December 2011.

The figures have been driven by the fact that 700,000 Android devices are now being activated each day, driving growth among the customer base. During the peak Christmas holiday sales period, 3.7 million Android terminals were activated in just two days.

When announcing the 10 billion milestone, it was noted that Android Market is now seeing one billion downloads per month. While this store was initially growing at the same pace as Apple’s App Store in the early stages of its development, it now has more momentum on its side.
