Microsoft's Internet Explorer market share fell below the 50 percent mark globally for the first time, according to StatCounter.
StatCounter found that IE market share fell to 49.87 percent worldwide in September. Firefox ended the month with 31.5 percent market share. Google's Chrome browser surged to 11.54 percent, up from 3.69 percent in September 2009.
StatCounter said that IE's market share fall globally had a lot to do with the European Commission mandating browser choice. In Europe, IE's market share is 40.26 percent, down from 46.44 percent a year ago. In North America, IE has a 52.3 percent market share, followed by Firefox at 27.21 percent and Chrome at 9.87 percent.
Net Applications, however, has IE at 60 percent market share.
