AdMob today posted what could be its last accurate study of data both before Apple's attempt to block AdMob and the formal acquisition by Google. Treating the update as a retrospective, the mobile ad producer characterized the past two years as the rise of the iPhone and noted it was the single largest platform, with about 43.8 million iOS devices requesting ads in May versus Android's 12.7 million. It almost single-handedly took over AdMob's top device requests and has a 40 percent share of smartphones by OS.
