both shows are spin-offs of All In The Family which is a remake of a British show. Good Times is actually a spin-off of Maude which itself is a spin-off of All In The Family.
i wasn't actually saying that Good Times and Jeffersons themselves were British shows. i was saying that most of what Norman Lear is famous for is either stuff that he didn't create or based on British shows. he's mostly known as a producer.
