It's interesting that LaserDiscs were popular. They were quite niche in the West so I imagine they must have been expensive to produce. Who even made the machines?

They always panic slightly thinking we're trying to give it to them (most libraries are inundated with out of date materials people donate), and are happy to give us names and numbers of churches and elderly centers who might take them.
It's not a ton of work and worth it overall.
the lab I was working at had an internal cable-tv network (which also ran ethernet on some of the channels), so we got a channel and hooked that to the output of the switch.
so you could get live visualization outputs from your office, or route them to the recorder to store your frames, and play them back at a smooth 30fps interleaved whenever you wanted.
