Although Microsoft recently touted the 100 millionth installation of Internet Explorer 7, Web measurement firms said that the new browser is simply being swapped out for older editions and hasn't had an impact on Firefox's continued climb.
"[As of] January 8th, we had the 100 millionth IE7 installation," said Tony Chor, an IE group program manager, in an entry on the team's blog. "Even more important than installations is usage. According to WebSideStory (the company we use to measure browser usage), as of this week, over 25% of all visitors to sites in the U.S. were using IE7, making IE7 the second most used browser after IE6.
"We expect these numbers to continue to rise as we complete our final localized versions, scale up AU [Automatic Updates] distribution, and with the consumer availability of Windows Vista on January 30, 2007," Chor added.
