As Expected, 2011 Was A Big Year For Mobile…

Nielsen recently released its Quarterly State of the Media - Mobile Media Report for Q3 2011.  And while we all expected 2011 to be a big year for mobile, just how big is pretty amazing…

Here are some of the more interesting findings from the report:

• 44% of U.S. mobile subscribers now own a smartphone device.  This is up from 18% just two years ago.
• The majority of mobile subscribers 18-24 and 25-34 have smartphones, with 53% and 64% penetration respectively.
• Android continues to eclipse every other smartphone platform, with 44% of the market.  iOS is second with 29%.
• Windows has completely failed to penetrate the market, showing just 1% to 2% in every age group.
• Google and Facebook are by far the most popular mobile websites among Android and iPhone owners.
• App Downloads have increased very significantly for Android in the past two years.  In 2009, only 4% of smartphone owners downloaded an app on Android devices. In 2011, 49% of smartphone owners have downloaded an app on an Android device.
• The percentage of smartphone owners who have downloaded apps has dropped in every other mobile platform over the past two years.
