I do not know about your local PBS station, Alixz, but ours it much like the commercial networks, hidden adverts, and dreadful pledges. I avoid it just because of that. Unless, they have a good British mystery show on Sunday nights. Just recently, in bored channel hoping, I came across an Iranian station . They were showing a documentary about Russia & Iran. I do not understand a word of Farsi, but I watched, fascinated for the whole hour.
