The company has been on a self-deprecating mission to force users into upgrading into newer versions of the browser.
Now the campaign has almost reached its conclusion according to a Microsoft blog post, which showed employees celebrating the demise with a specially decorated cake.
"IE6 has been the punch line of browser jokes for a while, and we've been as eager as anyone to see it go away. I'm thrilled to say that the United States has joined the ranks of Austria, Poland, Sweden, Denmark, Finland and Norway in dropping below 1% usage of IE6," said head of IE marketing Roger Capriotti.
"In addition, the Czech Republic, Mexico, Ukraine, Portugal and the Philippines are also entering the Champions Circle. We hope this means more developers and IT Pros can consider IE6 a "low-priority" at this point and stop spending their time having to support such an outdated browser."
IE6 was first introduced in 2001. The company is now testing the tenth, and much-improved iteration of the browser.
