Communications Primer

You might think that a movie about information from 1953 couldn’t possibly be relevant in the age of iPhone apps and the Internet but you’d be wrong. A Communications Primer, directed by that power couple of design Charles and Ray Eames, might refer to some hopelessly quaint technology – computer punch cards, for instance – but the underlying ideas are as current as anything you’re likely to see at a TED talk. You can watch it above.

In fact, the film made for IBM was the result of the first ever multi-media presentations that Charles Eames developed for the University of Georgia and UCLA. Using slides, music, narration and film, Eames broke down some elemental aspects of communications for the audience. Central to the film is an input/output diagram that was laid out by Claude Shannon, the father of information theory, in his 1949 book, The Mathematical Theory of Communication. As the perhaps overly soothing narrator intones, any message is transmitted by a signal through a channel to its receiver. While in the channel, the signal is altered and degraded by noise. The key to effective communication is to reduce "noise" (construed broadly) that interferes with the message and to generally simplify things.
