You dated me on this post, as I was born in 86. I thinly remember laser discs being used for one thing. When teachers were sick and substitutes had no idea what they were doing with the class. In came the large rolling cart, with its three tiers: one to hold the VCR, one to hold the laser disc player, and one to hold the massive CRT monitor. Those massive "CD's" changed the way I think about the physical world, laser discs paved the way for epic Blue Planet 2 in 4k. I know way off topic, but I had to share my notable laser disc memory.
