This is a key element in the structure of a news program and all by itself refutes any claim that television news is designed as a serious form of public discourse. Imagine what you would think of me, and this book, if I were to pause here, tell you that I will return to my discussion in a moment, and then proceed to write a few words in behalf of United Airlines or the Chase Manhattan Bank. You would rightly think that I had no respect for you and, certainly, no respect for the subject.
