The holiday season wasn’t too cheerful for Microsoft, at least when it came to its Windows Phone business. According to a new report from comScore, Microsoft lost market share during the three month period ending December 31st.

Obviously, that’s a critical holiday sales period, a time when many people pick up new mobile devices. However, consumers are increasingly turning to Android — which saw its market share jump 2.5 percent — and Apple — which released the new iPhone 4S in October and saw its share jump 2.2 percent.

Windows Phone, on the other hand, saw its share drop from 5.6 percent to 4.7 percent. On the bright side, that wasn’t as bad as RIM. The maker of the BlackBerry saw its market share fall 2.9 percent.

The report found that 97.9 million people in the U.S. now own a smartphone, representing 40 percent of all mobile subscribers.

Here’s a look at the top mobile device makers as reported by comScore.
