Television has achieved the status of “meta-medium”—an instrument that directs not only our knowledge of the world, but our knowledge of ways of knowing as well.

“Now ... this” is commonly used on radio and television newscasts to indicate that what one has just heard or seen has no relevance to what one is about to hear or see, or possibly to anything one is ever likely to hear or see. The phrase is a means of acknowledging the fact that the world as mapped by the speeded-up electronic media has no order or meaning and is not to be taken seriously.

[...] There is no murder so brutal, no earthquake so devastating, no political blunder so costly—for that matter, no ball score so tantalizing or weather report so threatening—that it cannot be erased from our minds by a newscaster saying, “Now ... this.” The newscaster means that you have thought long enough on the previous matter (approximately forty-five seconds), that you must not be morbidly preoccupied with it (let us say, for ninety seconds), and that you must now give your attention to another fragment of news or a commercial.

Marshall McLuhan used to call “rear-view mirror” thinking: the assumption that a new medium is merely an extension or amplification of an older one; that an automobile, for example, is only a fast horse, or an electric light a powerful candle.

There is no more disturbing consequence of the electronic and graphic revolution than this: that the world as given to us through television seems natural, not bizarre.

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.

Television is our culture’s principal mode of knowing about itself. Therefore—and this is the critical point—how television stages the world becomes the model for how the world is properly to be staged. 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.
