At the expense of Microsoft's Internet Explorer, Google's Chrome has secured a 10% market share for the first time ever, according to Web metrics company Net Applications. What's more, Google's Web browser more than doubled its share over the past year, beating its own expectations for market penetration. In 2009, Google hoped that Chrome would have 5% of the market by September 2010, and 10% for September 2011. "Unless Chrome stalls, Google's browser should own a 16% share by September," writes PCWorld.

Meanwhile, Microsoft's Internet Explorer lost 1.4% points of usage share in December, the largest one-month decline in more than two years. According to Net Applications. IE's total share fell to 57.1%, another record low for Microsoft's browser. Overall, IE has lost 5.6% points in the last 12 months, and 10.7 points since IE8 was introduced in March 2009. Also of note, Apple's Safari share of the market rose to 5.9% of the market at the end of the year, while Firefox and Opera Software's Opera both gained small amounts of share last month to finish the year at 22.8% and 2.2%, respectively.
