Yeah, that channel is where I learned it as well. I probably should have linked it.
Basically every video he does scratches that itch of learning a new thing about the world. The analog video series is indeed especially fantastic (laserdisc, VHS, B&W vs color TV, blu-ray, etc).

I'd recommend pretty much all of his video series to anyone in the HN crowd that's at all interested in analog media formats:
