What Liberal Media?

So there's this memo going around ABC Radio Networks, listing companies that have insisted that their advertising should not run during Air America's programming. The companies include Avon, Bank of America, Exxon Mobil, Federal Express, General Electric, Hewlett Packard, Johnson & Johnson, McDonald's, Microsoft, Wal-Mart, and the U.S. Navy.

As far as I know, none of these companies have insisted that their ads be removed from broadcasts made by Fox or its affiliates.
