I'm not sure it's ever been banned. As Hugh notes, it's available on the BBC store. I suspect it's not shown for the same reason Are You Being Served is not shown. Not so much because of offensive content, more that they are unsure how many viewers it would get. They keep showing Dad's Army because they *know* it'll get a lot of viewers.

That said, I think a lot of people who complain about these "racist" TV shows don't necessarily fully understand what they complain about. Take the various Alf Garnett shows. Various people have complained that those shows are massively racist and the character is. However, as the show's creator Johnny Speight apparently asked in an interview, who is the one person who loses out most as a result of all Alf Garnett's actions and schemes? Alf himself. The show is not so much about criticising various cultures and races of people, more about showing the racist himself being stupid.
