Premise: 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?

Hypothesis: Public channels feel free to push the envelope in terms of content unlike commercial channels.
Relation: contradiction
