While TV was once characterized by the medium from which it was delivered to us, a box with a tube, today that has all passed away just as the cassette and 8-track tape has for delivering us music. The content is not what has changed, in the larger sense, it is the medium that has changed. Today we get our music on CD’s or more often straight off the Internet from iTunes, Amazon, or some other digital service. We don’t even have to purchase it today - we can stream it via Pandora, Spotify, YouTube, or one of the thousands of Internet Radio Stations. Aside for the changes in genre’s our music is still… well… music — audio content.
Content vs. Medium
In the last 10 years Television has taken a similar change from one traditionally referring to a picture tube in a box, to the content of visual information — the visual content. Now one might still refer these two to an audio medium and a visual medium, but that is not so. The medium is describing the means by which the content is delivered. By definition the medium is the intervening substance through which the content comes to you. So the visual medium is the way in which you get the content — the content does not change, the way we get it changes.
By Definition
TV is Television, by definition — Tele-Vision, Televised Vision, transmitted visual information, transmitted, transferred, delivered, via wire or wireless — delivered content to the receiver. The term tele was first used before radio existed — telegraph. It was transmitted via wires then wireless via radio waves. It was a code (content) that was delivered to the receiver. The propagation medium and the devices used in delivering and receiving that content have changed but the information or content are what has always been what we care about — not the means of delivery. The message not the messenger is what is important. The end game.
