I believe that, because I am one.
I no longer watch Fox News in the morning (more than a few minutes anyways) because of the god-awful "commercials" that go with it.
I don't know if it's my local cable company or Fox doing it, but the constant repetition of those "public service" or "ad council" spots has driven me away .
Example: the one where the lady screams at Ed McMahon, "We Won...". I never want to hear that horrible screech again, therefore I'll gladly listen to NPR in the morning instead of Fox News.
