Delightful as curious time capsule, but also incredible to see the amount of time and resources devoted to a segment on a nightly news program. All those interviews with the actual people doing the work, no talking heads traipsing down to a green screen! Ten whole minutes of reporting at a stretch! And on a subject that, while certainly interesting, could hardly have been considered world-shattering at the time. Not really the sort of thing we get these days.
