Google's Chrome Web browser finished 2010 just shy of the 10 percent mark, notching 9.98 percent of browser market share through December in a year where it started at 5.2 percent.
Chrome's gain came at the expense of market leader Microsoft Internet Explorer, which fell to 57 percent from 58.41 through November. Mozilla Firefox remained static at 22.81 percent. Apple's Safari browser leapt to 5.89 percent from 5.57 percent in November.
Cracking double-digit market share is a big deal for Chrome, which has grown considerably since its September 2008 launch without the benefit of an official platform on which to run.
