Google's Android is still the top smartphone operating system (OS) in the Millennial Media ad network, but Apple's iOS regained some lost ground in March 2011, on the strength of the Verizon iPhone, according to Millennial Media's Mobile Mix report.
Overall, smartphones* accounted for 64% of all ad impressions on the Millennial Media ad network in March. Among key findings in March:
- Apple's iOs accounted for 31% of all ad impressions, up 11% from February.
- Android accounted for nearly one-half (48%) of all ad impressions.
- RIM grew 29% to capture 18% of all ad impressions, likely due to the increasing popularity of the BlackBerry Torch, according to Millennial Media.
- Nokia's Symbian and Microsoft's Windows Phone remained flat, each retaining a 1% share.
