Google Makes Its First Real Stab at Mobile Marketing: AdWords on iPhones

Google is letting advertisers who buy AdWords–its main revenue engine–automatically buy mobile advertising, too. The company says AdWords buyers can choose to have their AdWords automatically show up on phones that support “real” Internet browsers like T-Mobile’s G1 phone and Apple’s iPhone. That’s a relatively small market, but one that’s growing fast, and Google’s first real opportunity to show that it can make money on mobile.
