Poor MySpace. NewsCorp thought it was getting a bargain when it nabbed MySpace, once the top social networking site, for a paltry $580 million. Now, it looks like Rupert Murdoch has only been able to wrangle one potentially interested buyer for the site. All Things Digital writer Kara Swisher reports that "the main bidder is a dark horse bidding group, which includes Activision Chairman and CEO Bobby Kotick as one of the potential investors." Though MySpace's final selling price is still unknown as of now, Swisher insists that "one thing is certain: It is nowhere near the $100 million that News Corp. reportedly sought."
