Various tv shows have been pulled because although they were made at a certain time, they are considered racist. I am not sure about removing them from public viewing but what could be worse than the ever so funny English tv show Love Thy Neighbour. You can find clips on Youtube where Eddie calls his black neighbour a nig nog or a darkie. But maybe it wasn't so bad as it may seem. The 'darkie' was smarter than Eddie and always came out on top. They were drinking mates, trading insults. He was certainly much nice looking than Eddie.
While this link takes you to an earlier time, it is good that the history is on recent records. My goodness, doesn't Dame Barbara Castle look like a piece of work.
