Internet Explorer is losing market share, while Firefox and Google Chrome are posting big gains. But what’s really interesting is how Windows 7’s share has more than quadrupled since last month, even before the operating system goes on sale to the public. On the browser front, the data from Web metrics firm – Net Applications says Internet Explorer’s share was down 1.26 percent in September, dropping its total share to the still-dominant 65.7 percent. Firefox trails with 23.75 percent of the market in September, jumping 0.77 percent since August. Google’s Chrome is still struggling to make a footprint with 4.24 percent of the market, but it did gain 0.34 percent last month. Safari and Opera also saw small gains, while the legacy Netscape browser predictably dropped.
Now, for operating systems, Vista slid by 0.18 percent to 18.6 percent — the first ever loss in market share since January 2008. Windows 7 more than picked up the slack, gaining 0.34 percent to have 1.52 percent of the market. With IT professionals and for-pay developers getting access to the new operating system in August, we shouldn’t be blown away that market share is surging ahead of Windows 7’s October 22 release date, but it’s foreshadowing what should be huge gains in the months ahead as new computers pack the new OS.
