Google Chrome surpassed 20% of the global internet browser market during the month of June 2011 according to Internet statistics firm StatCounter.

Chrome took 20.7% of the global market, up from 2.8% in June 2009. Microsoft's Internet Explorer has fallen from 59% to 44% globally and Firefox dropped slightly from 30% to 28%.

"It is a superb achievement by Google to go from under 3% two years ago to over 20% today," commented Aodhan Cullen, CEO, StatCounter. "While Google has been highly effective in getting Chrome downloaded the real test is actual browser usage which our stats measure."

StatCounter Global Stats are based on aggregate data collected on a sample exceeding 15 billion page views per month (4 billion from the US) from the StatCounter network of more than three million websites.
