According to Net Application's December 2012 data, Microsoft's Windows Phone platform is ranked below Apple's iOS platform and Google's Android platform. In fact, Windows Phone only has 1.05% of the mobile market share, while Android owns 24.60% and iOS dominates with a 60.13% share.
The data even indicates that BlackBerry owns 1.59% of the mobile market share while Java takes about 10.18%. As the Windows Phone platform continues to grow, with the recent addition of Windows Phone 8, this market share percentage should increase in the coming months. Apple's iOS continues to dominate between Android and Windows Phone, so it is no surprise there. However, iOS has dropped from 61.10% to 60.13% while the Windows Phone platform went from .90% to 1.05% in just one month (November to December 2012).
