Old editions of BBC sketch show Little Britain have been taken off BBC iPlayer, Netflix and BritBox.
The follow-up Come Fly With Me is also no longer available on Netflix.
Scenes featuring the comedians playing black characters have been viewed as particularly problematic.
"There's a lot of historical programming available on BBC iPlayer, which we regularly review. Times have changed since Little Britain first aired so it is not currently available on BBC iPlayer," said the BBC.
At press-time Lucas and Walliams have not issued any new statements, but Lucas has previously said: "If I could go back and do Little Britain again, I wouldn't make those jokes about transvestites. I wouldn't play black characters. Basically, I wouldn't make that show now. It would upset people. We made a more cruel kind of comedy than I'd do now."
Walliams has previously said he would "definitely do it differently" today.
Little Britain was first broadcast on TV from 2003 until 2008. There was also a recent Brexit special on Radio 4 and a sketch on the BBC One charity fundraiser The Big Night In in April, prompting speculation that the duo might collaborate again on a new sketch show.
