Google CEO Eric Schmidt sat down with the Frantfurter Allgemeine (FAZ.net) to discuss things mobile and social networks among other things.
Just take the success of the iPhone: It has the first really powerful web browser on a mobile device – and many more are still coming. Nokia has one coming, Blackberry has one and Motorola has one. They are all supposed to be released this year. By these products, the advertising gets more targeted because phones are personal. So targeted ads are possible. And that means the value of the ads will grow. The next big wave in advertising is the mobile internet.
On social networks:
MySpace did not monetize as well as we thought. We have a lot of traffic, a lot of page views, but it is harder than we thought to get our ad network to work with social networks. When you are in social network, it is not likely that you´ll buy a washing machine.
Some good stuff in there. I recommend the full article.
