Charles and David Koch, two of the world's richest men, have walked away from talks to buy the Tribune Co.'s newspaper assets, concluding that the papers were not economically viable, Reuters reported yesterday. Their company, Koch Industries, continues to have an interest in the media business and is exploring a broad range of opportunities. The Daily Caller said that the brothers had decided not to pursue the newspapers, which include the Chicago Tribune and Los Angeles Times, as Tribune Co. plans for them to be separated from websites like CareerBuilder.com, which is owned by Tribune Co. This could leave the newspapers without an important source of revenue.
