Entertainment is the supra-ideology of all discourse on television. No matter what is depicted or from what point of view, the overarching presumption is that it is there for our amusement and pleasure. That is why even on news shows which provide us daily with fragments of tragedy and barbarism, we are urged by the newscasters to "join them tomorrow." What for? One would think that several minutes of murder and mayhem would suffice as material for a month of sleepless nights. We accept the newscasters' invitation because we know that the "news" is not to be taken seriously, that it is all in fun, so to say. Everything about a news show tells us this—the good looks and amiability of the cast, their pleasant banter, the exciting music that opens and closes the show, the vivid film footage, the attractive commercials—all these and more suggest that what we have just seen is no cause for weeping. A news show, to put it plainly, is a format for entertainment, not for education, reflection or catharsis. And we must not judge too harshly those who have framed it in this way. They are not assembling the news to be read, or broadcasting it to be heard. They are televising the news to be seen. They must follow where their medium leads. There is no conspiracy here, no lack of intelligence, only a straightforward recognition that "good television" has little to do with what is "good" about exposition or other forms of verbal communication but everything to do with what the pictorial images look like.

The book most directly deals with the paradigm shift which happened with the advent of television, and how it turned all public discourse into entertainment. Here's a good quote from chapter 6, "The Age of Show Business":
