According to the analytics firm StatCounter, Google’s Chrome web browser now has a 20.7% grip of the web browser market — seven times more than it had just two years ago. The boost comes at the cost of Microsoft’s Internet Explorer web browser, which now has less than a 50% hold on the market. Mozilla’s Firefox web browser has a 28% share of the browser market, down from 30% two years ago, and Microsoft’s Internet Explorer share fell to 44% from 59% two years ago. According to Reuters, StatCounter gathers its data from more than 3 million websites with more than 15 billion page views.
