Where Did Internet Explorer’s Browser Share Go?

Yesterday, browser market share figures came out from Net Applications, and the big news is how Chrome is moving up the ranks at the expense of Microsoft's Internet Explorer and even Firefox, compared to December.  But you have to look further back to get a sense of what is really happening. The various flavors of Internet Explorer (IE6, IE7, and IE8) together have 62.1 percent market share, down from 68.5 percent last March.  That is a 6.4 percent drop in about a year.  During the same period Chrome went from 1.6 percent share to 5.2 percent.  Firefox and Safari each gained about a percentage point each over the same period to 24.4 percent and 4.5 percent, respectively.  (Although Firefox is a tiny bit down since November, when it peaked at 24.7 percent).  If you add up the gains from those threeâ€"Chrome, Firefox, and Safariâ€"that is where most of IE's share went. But even that doesn't tell the whole story because if you look at share of individual versions of the different browsers, you can see another dynamic in play.
