It’s fairly obvious that Google and other companies see a future in mobile advertising. I must confess for as big of a phone geek as I am, I still remain skeptical. But when Google starts selling a physical device directly, something it has never done before, you know they are heavily invested in it. They aren’t the only ones, as Apple just bought mobile advertiser, Quattro Wireless. As I noted last year, even Porsche had a big win with mobile advertising.

The spend is there, JPMorgan notes that mobile advertising spend is up $2.6 billion or 62% in 2009. That’s not a typo, billion with a B. So it’s pretty easy to see why Google wants to heavily invest in mobile phones, it’s the next big thing for a company that’s made its fortune on mobile advertising. How about it readers? Have you ever been persuaded by a mobile ad?
