Rupert Murdoch has dropped his $580 million bid for Newsday. Cable operator Cablevision has offered $650 million for the Long Island daily, and Murdoch’s News Corp. said a higher bid would be “uneconomical.” The media tycoon’s dropout was unexpected, Reuters says, considering Murdoch recently told investors a deal was nearly done. A $580 million bid from Mortimer Zuckerman, owner of the rival Daily News, remains on the table. (More Rupert Murdoch stories.)
