Commercial channels pour programs down from the heavens that match or surpass the products of the public broadcasters, who are too cowed to produce anything as homo-proud as the new Ellen , as racy as Brooklyn South , or as culturally subversive as The Larry Sanders Show . I ask you, what PBS newsman out-wings the liberal Peter Jennings?
Public broadcasting is hampered by fears and can't produce progressive content on the same level as commercial broadcasters.
Public channels feel free to push the envelope in terms of content unlike commercial channels.
