For more than a decade, Microsoft’s Internet Explorer has been the predominant tool the world uses to connect to the Web, but that’s no longer true, according to StatCounter.

StatCounter, which tracks Internet data, said that IE’s share of the browser market fell to 49.9% in September for the first time. More people still use IE than any other single browser, but the combined market share of non-Microsoft browsers now outpaces IE.

“This is certainly a milestone in the Internet browser wars,” said Aodhan Cullen, StatCounter’s CEO. “Just two years ago IE dominated the worldwide market with 67%.”

The day Internet Explorer hits less than 1% usage, will be a happy day for web developers around the world.
