The rollout of the iPhone 3G has seen a large increase in the iPhone's global Web share, according to figures released Monday.
The figures, collected by Web analytics company Net Applications, show that in June 2008, before the launch of the iPhone 3G, the iPhone had 0.16 percent share of the operating system market, as measured by OS detection during Web browsing; and in July, it had 0.19 percent.
However, as of September 1, the iPhone had 0.3 percent of global market share, an increase of 58 percent in one month. According to Net Applications, this was due to the July launch of the iPhone 3G.
"The release of the iPhone 3G has brought large gains in Web-browsing share," said a Net Applications report. "Prior to the launch, iPhone usage share had leveled off, but has since resumed its upward trend."
In the operating system market, Microsoft Windows has had dominance for many years. However, a Net Applications report showed that dominance steadily, if slowly, decreasing. Whereas in October 2007 Microsoft Windows had 92.49 percent of the operating system market, in August 2008 that figure had dropped to 90.66 percent.
This fall has coincided with an increase in market share not only for the iPhone, but also for Linux and Apple Mac. Linux has steadily increased its market share, from 0.5 percent in October 2007 to 0.93 percent in August 2008. In the same time period, Apple Mac increased its market share, from 6.58 percent to 7.86 percent.
Microsoft's dominance of browser share is also declining, somewhat faster than its OS share. Internet Explorer usage fell from 78.36 percent in October 2007 to 72.15 percent in August 2008. Over the same time period, Firefox increased its market share from 14.97 percent to 19.73 percent, while Safari usage increased from 5.09 percent to 6.37 percent.
