A light bulb is an example of a medium. It conveys light. But a bare bulb conveys a different light than, for example, a lava lamp. Borrowing a phrase coined by a Christian visionary, I point out that the mediums we use to receive the message, seems more important nowadays than the actual message itself. Do you have an iphone or an android? A 55 inch tv or a 70?
