From the Information Aesthetics Weblog:

“A Communications Primer,” created in 1953, focuses on the aspects of “communication“, including the notions of transmission, noise, redundancy, distortion, misunderstanding, and much more

Anna Daly at Senses of Cinema describes it as follows: “Schematic diagrams and simple associations serve to highlight the message: clear communication betters humanity. The film is thus an accomplished work of design as well as being a beautifully composed documentary that brings an artist’s feel for colour and composition to the moving image, ensuring visual delight despite theoretical archaism.“
