I've loved this program for years and it's just turned 50.
Lots of old episodes are available on iplayer at the moment, so I'm having a great time watching old episodes especially this one,

Might only be available to UK residents but if you can watch it its called Horizon - 1977-1978: Now The Chips Are Down
Fascinating.
