We see mobile and social network advertising as major online ad opportunities. So do Google, Yahoo, Microsoft, Facebook and MySpace, for that matter. Yet progress has been painfully slow. Google co-founder Larry Page has said on earnings conference calls that social ads are challenging. Others have said social ads will never work. Meanwhile, these vendors also need to solve the quandary of the stingy third-screen on smart phones, where mobile ad placement is slight. We expect Google, with its wealth of ad resources, to light the way in the latter half of 2008.
