It is not merely that on the television screen entertainment is the metaphor for all discourse. It is that off the screen the same metaphor prevails. As typography once dictated the style of conducting politics, religion, business, education, law and other important social matters, television now takes command. In courtrooms, classrooms, operating rooms, board rooms, churches and even airplanes, Americans no longer talk to each other, they entertain each other. They do not exchange ideas; they exchange images. They do not argue with propositions; they argue with good looks, celebrities and commercials. For the message of television as metaphor is not only that all the world is a stage but that the stage is located in Las Vegas, Nevada.
—Neil Postman, Amusing Ourselves to Death, (New York: Penguin, 1985), 92-93.
