Android Passes iOS....Again

Android has surpassed iOS in yet another category, ad impressions on Millennial Media’s mobile ad network. Android garnered 46% of all ad impressions in December, while iOS had 32%. Android also accounted for more in-app revenue, 55% to 39%.

These are outstanding numbers for Android, but they reflect the fact that there are multiple devices on all mobile carriers in the U.S. that use the Android operating system. However, these numbers will change, probably dramatically, now that the iPhone is available on Verizon. And that still means that 2 of the big 4 carriers do not have a presence with the iOS.
