The UK 405-line system was almost certainly kept going for far longer

who could not receive the 625-line service. At the time, I recall that
many of us said that it would be cheaper simply to buy that last little
old lady, living in a remote valley in the middle of nowhere, a new TV
set and aerial.

Maybe it would have been better to have one 625 line network on VHF,
like most other countries used until analog closedown.
Of course going from 405 to 625 would have meant ther was no room for
two networks there.
