The UK high-end radio market post-WWII was stymied by two factors:

1] No FM broadcasts. Germany/France made the move to FM a decade before the UK agreed a standard and got itself off the launch-blocks and belatedly started to build a nationwide FM network.

Even then, it failed to put the most-popular BBC station - Radio1 - onto FM untill the 1980s!

2] Lack-of-competition: why would a prospective radio-purchaser invest in a FM/Stereo radio when all they could realistically receive would be the same old BBC Home/Light/Third-programs they already got on MW/LW ??

IMHO post-WWII the UK should have adopted a much more US-style free-market regulatory approach and allowed lots of new FM-stations to get on-air for minimal cost. Imagine if Caroline, Jackie etc could have been entirely legal just by buying a £50 Postmaster-General "Here's your frequency, transmit what you think will make money!" licence.
