I mean, they keep making shows just like it, nor was it the first of its kind. Base humor is an easy way to find footing in the fame game.
Jeeves and Worcester certifiably IS a historical landmark of British entertainment with a blackface naughty in it. Hugh Laurie, pleasant man though he usually is, gave the "but it was a different time" excuse but that left a bad taste in everyone's mouth, so they just don't talk about it anymore. That one does produce mixed feelings because it was a delightful adaptation of PG Woodhouse's classic, but they just weren't quite smart enough to ask if that was going to fly. I would have a conversation about Jeeves and Worcester before I'd ever have a conversation about Little Britain, though.
