IE 9 vies for its piece of the browser pie

According to NetMarketShare, a Web tracking and analytics service provided by Net Applications, Microsoft's latest version of Internet Explorer finished off May with 12.0 percent of the worldwide browser market.

The numbers are slightly better on Windows 7 machines, with 12.2 percent of global usage. Roger Capriotti, director for Microsoft's Internet Explorer product marketing team, commented in a blog post that the May worldwide market share number represents an increase of 60 percent over April's figure.

Capriotti noted an even stronger finish for IE 9 on Windows 7 in the U.S. market, saying that "in the US, IE9 has now passed 17 percent usage share on Windows 7 as of the last few days in May."

While the increases are good news for Microsoft's newest browser and operating system, IE 9 isn't showing the kind of growth that Google's latest Web browser has demonstrated, according to Net Applications' May data. Google Chrome 11 edged out IE 9 with 14.8 percent of the market. In addition, Chrome 11 had a month-over-month growth increase of 6.9 percent, according to Net Applications' May data. IE 9 is still a relatively new entrant, though, having been released in March.

If all operating systems are considered, IE 9's numbers aren't as strong, with just a 4.2 percent market share. IE 9 is limited to only running on Windows 7- and Windows Vista-based machines. While the numbers show a growth of 0.9 percent over the previous month, IE 9 has a lot of catching up to do to the market leader, Microsoft's own Internet Explorer 8, which continues to head the pack with 31.3 percent use.

Internet Explorer 6 finished second, with10.4 percent of the global browser market, while Mozilla's FireFox 4 finished up in third place with a 10.0 percent share.

These stats have nothing to do with install rate. They're about which browsers are actually being used actively to browse the web. Just because someone was 'tricked' into installing a new browser doesn't mean it made itself the default browser. Novice users who would install something by accident tend not to like change so they wouldn't keep using something they didn't want. And if they did, it's a valid stat. A general comment about the article - it's pretty misleading as the first two paragraphs imply that IE9 has such a high share across all operating systems (as it states the numbers look even better for Windows 7). Only later does it mention that the stats are much lower overall.

Let's examine the reason for Google Chrome So Called Dominance. You decide to download another freeware program say like this free app...err excuse me .. software program called CCLEANER, when installing it or lots of others, how many times do you see it offers Google Chrome as another install? If your like most folks and dont read what your installing and just say YES, Guess what you got .. Google Chrome. Now if IE9 was offered the same, I bet that install rate would be much higher. So dont tell me Google Chrome is not being forced to be installed. When it is packaged with other freeware applications now adays.
