Tribune reportedly has no shortage of deep-pocketed buyers for its Los Angeles Times newspaper, but so far the media company has declined the overtures.A report in the Los Angeles Times Saturday said that three local billionaires -- philanthopist Eli Broad, entertainment mogul David Geffen and supermarket tycoon Ron Burkle -- had expressed interest in buying the newspaper in separate letters this month to Tribune. The report cited people who had seen the letters and said that each billionaire was told the newspaper wasn't for sale, at least at the present time. The Times hasn¿t been under local ownership since 2000, when the Chandler family agreed to sell the company that then owned the newspaper to Chicago-based Tribune. Tensions have risen between the newsroom and management as Tribune has made staff and budget cuts in the face of decreasing revenue. Tribune shares ended Friday up 81 cents at $29.53.
