I ran across this documentary while looking for some video lectures by Neil Postman. A couple years ago I stumbled upon his book Amusing Ourselves To Death and found it to be a very interesting read especially in light of what I was going through at the time in regards to coming to understsand in a clearer way all the external controls we are surrounded by. Then last year I read Jacques Ellul's book The Humiliation of The Word and it helped describe in greater detail the problems created for us through the onslaught of images. If you have the time and are so moved to take the time to watch these videos or read either of these books I think you might find them very interesting and hopefully helpful.
"The orchestration of press, radio and television to create a continuous, lasting and total environment renders the influence of propaganda virtually unnoticed precisely because it creates a constant environment." Jacques Ellul
