The first phone featuring Google's green robot was T-Mobile's G1. You can argue that it was not widely popular and you will be right, but it did some of the dirty work to pave the way to the future of Android. And as a matter of fact, did Verizon have a lot of choice? Come to think about it, Verizon's main competitor AT&T was (and still is) in an exclusive deal with Apple and the iPhone was settling in everyone's wish list. Verizon had to bring up something and Android had the Google branding and all the other needed ingredients to fit. So in a way, this was a marriage of convenience, not only love. Was it beneficial for Android? Absolutely. But was it a one-way relation? Not necessarily.
What was Verizon's main contribution? Ads, ads and a bit of its rock solid network. Even Times Square was dominated by the huge digital Droid billboards and this was as spectacular as it gets. But maybe some credit should go to Android also. And with Gingerbread right around the corner things are about to get even better.
