I'm not sure why you are having a problem with this, maybe I need to explain this further. I am aware of the ratings, those are indeed "public opinion" I was referring to the the show in question, and if enough people object, that show will not survive, advertisers will pull out, and the executives will have little choice but to replace, or cancel the program. I believe we are on the same page, but one must certainly consider public opinion, or a public outcry from contraversial programs. This is all I am saying, you can't just say, "turn the channel" t.v does not work that way, and if you want a show to survive, you must consider A and B.
I hope that helps.
