The only consistently decent network is PBS. Quality shows on science, on history, on the arts. The Newshour tends to try to be so balanced that it gets predictable--if there's one side, by gum there must be another side as well (and never more than two, the good lord forbid). But they get more in depth with news stories than any other TV outlet, and often more than newspapers. And although every now and then they go on fund-raising toots, no commercials.
