When it comes to the mobile Web, increasingly there are only two mobile platforms which matter: Apple and Android. According to AdMob's October, 2009 mobile metrics report , the iPhone/iPod Touch and Android phones accounted for 75 percent of mobile Web traffic in the U.S., as measured by all the mobile ad requests it tracks. That number is up from a combined 65 percent in September, 2009. The iPhone is miles ahead of everyone else, but Android is quickly rising as a strong second. While Android phones managed to increase their share from 17 percent in September, 2009 to 20 percent in October, 2009, the iPhone and iPod Touch gained even more, going from 48 percent to 55 percent share. Meanwhile, during that same month the Blackberry 's mobile Web traffic share went down from 14 percent to 12 percent, and Palm's webOS shrank from 10 percent to 5 percent (Ouch).
