Uh ... sure. Without PBS, we'd never see any shows on cosmology, biology, archeology, paleontology, geology, anthropology, evolution, philosophy, or even those YEC favorite subjects like alchemy, shamanism, mysticism, witchcraft, crop circles, false gods and religions (to quote the Highlander, "There can be only one!"), and, of course, those money-grubbing, televangelist con-men.
On the other hand, if you have cable or satellite TV, you can have all of the above 24/7 without viewing PBS at all.
