I remember pre-Internet Radio 4 being incredibly frustrating, as they'd have excellent programmes, but the chances of actually catching them was far more fleeting than a TV show, as there was no readily available technology analogous to a video recorder. The very best (eg the Lord of the Rings dramatisation) would (eventually) be released commercially but vast amounts of quality output would never reach the people who'd appreciate it.
