For a home video recording made 47 years ago, the visual quality of this commercial compilation is phenomenal.
For kids who've grown up with high definition digital television but are interested in analog retrotech, this recording comes the closest I've encountered so far at capturing what a good over the air standard definition broadcast signal in the seventies looked like at home. [Edited to add: When I watched it on my Fire tablet, it looked the way I described it in the previous sentence. When I watch it on my laptop, it looks nowhere near as good or like analog broadcast. So, mileage may vary depending on your computer. Sorry.]
[Also: there's a PSA about the metric system at around the 25 minutes mark.}
