Also, most of the British shows were made in the days before multi-channel TV became commonplace. And I'd argue that there are more black faces on TV today - you are more likely to see them in prime-time drama series, for example - those made here (the BBC is slightly better in this respect), and definitely US imports. And rare you'll find programmes aimed at kids/teenagers that black folks don't feature in. Unless there's good reason (e.g the Windrush anniversary), I'm not sure the kind of 'black-led' series we used to see would be made in these times.

TV today is driven by different priorities and values, for all sorts of reasons. More black faces has definitely not meant better. Personally think theatre is a safer bet for seeing decent black acting talent.

PS Angie LeMar sketch show was probably 'Get Up, Stand Up'; the Friday night shows went under the title of 'The A-Force'; the two black comics might have been Curtis and Ishmael, but can't remember the name of the show.

PPS None of the above were a match for 'No Problem', by far the best 'black British' comedy show ever made, IMO.
