Nielsen: Windows Phone Has a 1.7% Share in US

Nielsen has released some smarpthone market share figures for March. The metrics firm says that 50.5% of US mobile phone owners now carry smartphones. The data show the following breakdown by operating system:

  • Android OS -- 48.5%
  • iOS -- 32.0%
  • Blackberry -- 11.6%
  • Windows Mobile -- 4.1%
  • Windows Phone -- 1.7%
  • Other -- 2.1%

Here's comScore's March data for comparison purposes:

  • Google -- 51.0%
  • Apple -- 30.7%
  • RIM -- 12.3%
  • Microsoft -- 3.9%
  • Symbian -- 1.4%

Comscore puts smartphone penetration at 45.2% in the US by comparison. 

There's a meaningful difference in the numbers in terms of Android and iOS market share percentages in both data sets. In addition Nielsen shows 5.8% penetration of Windows, while comScore shows 3.9%. That's also a fairly significant difference. 

They both agree however that the Windows Phone platform so far hasn't moved the needle and Microsoft's overall share of the smartphone market is declining.
