First off I dont have concrete advertising data but from my subjective observation it seems Verizon is constantly advertising Android. Before the iPhone they used to tout their network in advertising campaigns such as 'Rule The Air'. Now its all about Android. On my commute to/from work and on nightly television they are constantly advertising Android. Especially older phones such as the Incredible which is a 10 month old phone. Is it because advertising costs are subsidized by manufacturers? Does the iPhone not need advertising? Is there higher profit margin with Android phones?
