McLuhan understood "medium" in a broad sense. He identified the light bulb as a clear demonstration of the concept of “the medium is the message”. A light bulb does not have content in the way that a newspaper has articles or a television has programs, yet it is a medium that has a social effect; that is, a light bulb enables people to create spaces during nighttime that would otherwise be enveloped by 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."[2]I've never heard anyone say that the medium is not the message, but I suppose that such a quote would simply be someone disagreeing with the original phrase as coined my McLuhan.
Likewise, the message of a newscast about a heinous crime may be less about the individual news story itself — the content — and more about the change in public attitude towards crime that the newscast engenders by the fact that such crimes are in effect being brought into the home to watch over dinner.[3]
McLuhan defines medium for us as well. Right at the beginning of Understanding Media, he tells us that a medium is "any extension of ourselves." Classically, he suggests that a hammer extends our arm and that the wheel extends our legs and feet. Each enables us to do more than our bodies could do on their own. Similarly, the medium of language extends our thoughts from within our mind out to others. Indeed, since our thoughts are the result of our individual sensory experience, speech is an "outering" of our senses - we could consider it as a form of reversing senses - whereas usually our senses bring the world into our minds, speech takes our sensorially-shaped minds out to the world.posted by Sticherbeast at 8:00 PM on January 16, 2012 [1 favorite]
But McLuhan always thought of a medium in the sense of a growing medium, like the fertile potting soil into which a seed is planted, or the agar in a Petri dish. In other words, a medium - this extension of our body or senses or mind - is anything from which a change emerges. And since some sort of change emerges from everything we conceive or create, all of our inventions, innovations, ideas and ideals are McLuhan media.
Thus we have the meaning of "the medium is the message:" We can know the nature and characteristics of anything we conceive or create (medium) by virtue of the changes - often unnoticed and non-obvious changes - that they effect (message.) McLuhan warns us that we are often distracted by the content of a medium (which, in almost all cases, is another distinct medium in itself.) He writes, "it is only too typical that the "content" of any medium blinds us to the character of the medium." (McLuhan 9) And it is the character of the medium that is its potency or effect - its message. In other words, "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."
