Tribune Co. CEO Sam Zell announced he does not intend to sell any more of the company's newspapers, after selling Newsday to Cablevision Systems Corp for US$650 million, Reuters reported Wednesday.

Tribune Co. is trying to pay off its debt of nearly US$13 million by selling properties like the Chicago Cubs baseball team, and downsizing and redesigning papers.

"We're looking at some of the worst advertising numbers in the history of the world,” said Zell, according to the Baltimore Sun. "I have a responsibility ... to keep this business alive when cash flow has eroded at a prodigious level.”

Potential buyers showed interest in purchasing The Baltimore Sun. Meanwhile, the only public bid for The Hartford Courant, “would make no financial sense”, Reuters reported.
