From Bloomberg:
The world’s biggest online social networking service, Facebook, has ditched an exclusive banner advertising deal with investor Microsoft in favour of an expanded internet search and text advertising deal with the software giant.In the swap Facebook will take back control of banner ads on its web properties as Microsoft continues to try to wrest a greater slice of the search advertising market from rival Google – estimated to handle about two-thirds of US web queries – through its own search engine, Bing.
