The book proposes that media themselves affect their content in important ways. It is an attempt to understand how changing media have affected society. McLuhan suggests that media play a role, not by the content delivered, but by the characteristics of the medium itself.
McLuhan pointed to the light bulb as an example. A light bulb does not have content in the way that a newspaper has articles or a television has programs, but it is a medium that has a social effect. The light bulb lets people do things at nighttime which would be impossible in darkness. He describes the light bulb as a medium without any content. McLuhan states that "a light bulb creates an environment by its mere presence".
More controversially, he thought that content had little effect on society — for example, it did not matter if television broadcasts children's shows or violent programming — the effect of television on society would be identical. He noted that all media have characteristics that engage the viewer in different ways; for instance, a passage in a book could be reread at will, but a movie had to be screened again in its entirety to study any individual part of it. He made the point that reading, by its very nature, is a sequential medium. One reads it in a sequence. On the other hand, a medium like film presents information more holistically. There is a kind of "all at once-ness" about films and television.
The book is the source of the well-known phrase "The medium is the message". It was a leading indicator of the upheaval of local cultures by increasingly globalized values. The book's influence spread much further than academics, writers, and social theorists. It was widely read. It became a corner-stone in media studies courses.
