Yahoo and Bebo = True
Google has MySpace, Microsoft has Facebook and now Yahoo has become the exclusive display ad provider for popular social networking site Bebo. Bebo reportedly has 38 million users globally, with its most popular sites in the UK and Ireland, although the company is based in San Francisco. Bebo search has been "powered by Yahoo" since roughly June of this year. And there are been several rumors of attempts to acquire Bebo, for up to $1 billion, including by Yahoo. I would imagine that these deals (search, display ads) now would make Yahoo a likely front runner in any new acquisition scenarios.
