You can probably see the issue here.
In its heyday, it was a huge ratings hit, achieving viewing figures in excess of 20 million in the early 1960s. Complaints about the show's racism began popping up by 1963 and only intensified afterward, eventually forcing the programme's cancellation... in 1978, with the traveling stage show continuing until 1989. Yes, really.
Today, The Black and White Minstrel Show is a major source of embarrassment to most if not all concerned - especially the fact that it was allowed to run for as long as it did.
- Black Face: At the core of the show. Most of the performances featured white male performers in blackface, along with white females who retained their normal appearance.
- Crossover: A rather strange one on 12 December 1964, when the programme was invaded by Daleks. At this point, the Daleks were appearing in their second-ever Who story ("The Dalek Invasion of Earth"; Episode 4 aired that same night) and had been established as a force to be reckoned with, so here they...took part in dance routines. No, seriously.
- Long Runner: 31 years between the TV and stage shows, which is way, way too long for something like this.
- Minstrel Show: As the title indicates.
- Spin-Off: Two, both by the BBC, in response to complaints of racism.
- The first, Masquerade, aired in 1968. Here, the main singers appeared without blackface and the black singers wore whiteface, which...didn't exactly make things much better.
- The second, Music Music Music, outright replaced the parent programme in 1969 and had the performers donning no race-based makeup whatsoever. Unfortunately, this only lasted one series, after which the parent programme returned.
- Variety Show: Each episode featured a range of musical numbers.
