Android's US ad impressions double that of iOS in Q3 2011, reports Millennial
Two horse race with RIM trailing in third
Shifting from a monthly analysis to a quarterly report for the first time, there was little change in Millennial Media's look at the US smartphone market during the third calendar quarter of 2011.
As has been the case since the end of 2010, Android remains the dominant smartphone platform according to Millennial's figures, with a 56 percent share of the firm's smartphone mix.
However, while that represented the same 2 percent rise for Google's platform as iOS enjoyed from the figures posted at the end of Q2, Android's share is now exactly double that of Apple's.
The top twoThe rest of the market almost seems insignificant in comparison.
Both BlackBerry and Windows Phone managed to lose share in Q3 – the latter dropping to 1 percent, while RIM's platform shed 2 percentage points.
Indeed, in terms of physical sales and app ad spend, the market is split between just two players: Android and iOS.
Apple can boast the best selling handset on the market during Q3 – iPhone lapping up 12.6 percent of ad impressions per device - while Android accounts for the larger share of ad spend, hitting 49 percent to iOS's 41 percent.
Interestingly, that's an exact reversal of the position the two platforms found themselves in back in June, when Apple's OS generated the 49 percent of all app ad spend.
