The BBC is reporting that Microsoft is in talks with Facebook in an apparent attempt to acquire a position in the social networking site. The Wall Street Journal has the price tag for a 5% stake at between $300 million and $500 million which would value the company as high as $10 billion! Google is also thought to be interested but analysts have Microsoft pegged as favourites considering an existing relationship between the companies that has Microsoft as the exclusive provider of advertisements on the site.
