Random--I know, but if you've got ten minutes to waste, why not learn something.
I ran across this video the other day and thought it was pretty interesting. It was made in 1949 in northern Canada. Watching this feels so much like something that would have been shown to us in elementary school. I can almost feel the rough, itchy, horribly colored, all-weather carpet underneath me as we all settle down on the floor while the teacher rolls the TV in on an unusually tall cart. Then she struggles with the VCR trying to get the video to play. Once the video starts to play we have no sound and after watching the first minute or so she figures that part out, rewinds the tape and finally starts the video from the beginning with everything working.
