Quite honestly, the Brits produced some seriously dire programmes back in those days, although they steadfastly believed they made the "best programmes" in the World.
Sturgeon's Law isn't just for books, nor for one country!
Some of the seriously dire programmes were extremely popular. I always hated (and was bewildered by) "The Black and White Minstrels"; nowadays it is still useful as a simple quick example of how much progress has been made. Others include "Love Thy Neighbour". (Curiously, modern idiots take "Till Death Us Do Part" as being a documentary whereas it was actually a satire).
I always found Black & White Minstrels" cringeworthy, as I couldn't see why the dancers had to wear blackface.
Sing the songs, maybe, but there was no reason to promote stupid stereotypes, no black person ever having looked like that!
From memory we also had it on TV in Australia back in the 1960s---I guess I must have been "woke" back then!
I still couldn't abide Alf Garnett, although it was a magnificent portrayal of an "Ignorant old Pommy Bastard" on the part of Warren Mitchell.
Funny thing, although I initially thought him "over the top", I met blokes like him, (all Brits) both in Oz, & during my long ago stay in the UK.
I even worked with a chap who was pretty much the manifestation in every way of another English stereotype----"Andy Capp".
Old, short & ugly, he would regale us with stories of his romantic dalliances, just like his cartoon "alter ego" who spent his time chasing what were called in that faraway time, "Dolly Birds".
Meanwhile, relatively normal, quite pleasant blokes were mostly pessimistic about their chances with members of the opposite sex.
