This is one that popped up via Infosthetics. The following movie uses PICOL icons (short for Pictorial Communication Language) to show the history of the internet, going back to 1959. (I have to admit, at over 7 minutes, I started to skip after a minute). The comments are worth looking at as well: one perceptive poster points out that it's default these days to show the internet as a cloud, but in reality it's a very recent metaphor.
