This is merely to say that the personal and social consequences of any medium - that is, of any extension of ourselves - result from the new scale that is introduced into our affairs by each extension of ourselves, or by any new technology."

But what does it mean? How can the medium be its own message?

Many people presume the conventional meaning for "medium" that refers to the mass-media of communications - radio, television, the press, the Internet. And most apply our conventional understanding of "message" as content or information.
