A spokesman for Tribune Co. could not be reached for comment, nor could representatives of News Corp. and Zuckerman. A spokeswoman for Cablevision said the company would not comment on the reports.
A sale of Newsday would help Tribune Co. reduce its debt. On Thursday the company posted a $78 million loss from continuing operations in the fourth quarter compared with a profit of $233 million in the year-earlier period. National advertising revenue fell 11% for the quarter, primarily due to decreases in the transportation, telecom/wireless, technology and health care sectors. These were partially offset by gains in the financial category.
