Report: Google, Microsoft, and two media companies bidding on Digg

TechCrunch reported early on Friday that four companies are in the running to place bids on Digg--Microsoft, Google, and two unidentified "media companies"--and that a sale may happen soon. It'll likely be less than the $300 million that Digg was once rumored to go for; TechCrunch's Michael Arrington cited sources who said that Google is prepared to bid $200 million to $225 million and that Microsoft, which currently serves ads on Digg, is aiming slightly lower. That's a good bit less than the $300 valuation that was floating around when Digg reportedly hired investment bank Allen & Co. to shop it around.

As for the media companies, no specifics are given, but keep in mind that Digg has deals with several traditional media companies' online arms, like CBS and News Corp.
