Light On Light Through

Welcome to Light On Light Through, Episode 93, in which I explore how Marshall McLuhan's "tetrad" or four laws of media, first publicly propounded in the mid-late 1970s, can explain the "selfie" which didn't exist until a few years ago and is so vividly in evidence today.   This is the photograph which instigated this train of thought - thanks to Ian Bogost for pushing it out of the station.     You might also enjoy this podcast episode: Marshall McLuhan and the Kindle.  See also Tetrad on Eyeglasses Fliiping into Google Glass and Photography Flips into Snapchat. more about McLuhan
