Android Nabs Third Of Smartphone Market, BlackBerry Plummets

Google’s Android now holds more than a third of the U.S. smartphone market share, eclipsing both RIM’s BlackBerry OS and Apple’s iOS with a growing lead, comScore reports.

Measuring more than 30,000 U.S. mobile subscribers through its MobiLens service from December 2010 to March 2011, ComScore found that Android now holds 34.7% — a solid increase from 31.2% in January, which was when Android jumped ahead of RIM as the top smartphone platform in the U.S. for the first time.

Apple held its own, growing from 25% in December 2010 to 25.5% in March 2011. It seems most of Android’s growth was at the expense of RIM, which dropped from 31.6% to 27.1% in that same period.

Microsoft and Palm, which hold the fourth and the fifth place on the list, also lost a fair share of subscribers, dropping to 7.5% and 2.8%, respectively.

On the mobile equipment manufacturer front, very little has changed. Motorola dropped from 16.7% to 15.8% from December 2010 to March 2011, and the only company that experienced significant growth in this period was Apple, which grew from 6.8% to 7.9%, largely due to the iPhone launching on Verizon in February.
