SNOOZEDAY Rupert Murdoch does not plan to up his $580 million offer for Tribune Co.'s Newsday, even though Cablevision bested his pitch with a $650 million bid. This is either Murdoch's way of exiting the bidding, or his way of saying he's still a better owner even if he's not willing to cough up $70 million more. Oh, but also: Cablevision's offer includes the paper's real estate, so the offers are pretty much even.
