A new report published by Millennial Media paints a picture of the global smartphone landscape in April of 2011. The company found that Android continued its domination in pure market share, holding a 53% of impressions on the company’s network. Apple’s iOS came in second with 28% and RIM’s BlackBerry OS came in third with 16%; Symbian, Windows, and “other” totalled under 4% of impressions. While Google continues to maim and destroy in terms of handset numbers, Apple continues to hold the crown when it comes to application revenues. “Revenue generated from applications on the iOS platform grew 6% month-over-month and represented 50% of the Application Platform Mix on our network, ranked by revenue, in April,” reads the report. Android is in a close second with 39% of app revenues and RIM ranked third with 9%. What are users downloading? The report states that games, mobile social networking, and music/entertainment applications are the top application categories. Millennial Media sees over 142 million unique mobile impressions on its network each month from over 5,500 different devices.
