Apple leads the browser market when it comes to real-world usage on mobile devices. (Credit: Net Applications) New statistics released today show a competitive volatility in the the mobile browser market absent from the slower-moving personal computer browser market. Net Applications has long shown the total browser usage worldwide based on visits to a collection of Web sites using its analytics software. Now, though, it's separated PC browsing on desktops and laptops from mobile browsing on phones and tablets. With PCs, the story remains largely unchanged: Microsoft's Internet Explorer continues its gradual slide while Google's Chrome and Apple's Safari gradually rise. But in the mobile market, there's a lot more jitter in the statistics. Apple's Safari, used on iPhones, iPads, and iPod Touches, is the dominant browser, rising from 44.3 percent of usage in October 2010 to 53.0 percent in August 2011. And although the overall ranking of the top five browsers hasn't changed in the last year, it appears likely Google's unbranded Android browser will take the No. 2 spot from Opera Mini in coming months. From October 2010 to August 2011, Opera Mini dropped in usage from 32.4 percent to 20.8 percent. Android's browser rose from 9.2 to 15.7 percent, according to the Net Applications statistics. Also on a downward trend is the Symbian browser, which dropped from 8.1 percent to 5.8 percent. Blackberry's browser, in fifth place, edged from 2.7 percent to 2.9 percent. Mobile browsing deserves more attention on its own now, Net Applications said. "The combination of mobile and tablet usage has continued to rise dramatically and is now over 6 percent (and accelerating) of all browsing on the Internet," the company said. With Net Applications' new methodology, the personal computer browsers didn't change place, but Chrome came out better and Safari came out worse once the mobile browsers were split off into their own category. For computer browsers under the new methods, IE dropped from 61.0 percent to 55.3 percent from October 2010 to August 2011; Firefox dropped from 23.6 percent to 22.6 percent; Chrome rose from 8.8 percent to 15.5 percent; Safari rose from 3.9 percent to 4.6 percent; and Opera dropped from 2.3 percent to 1.7 percent. In the personal computer browser market, Chrome is catching up to Firefox.
