Four episodes of the US hit series in which characters appear in blackface are to be taken down, at the request of creators Tina Fey and Robert Carlock.
Fey apologized for pain 30 Rock has caused.
The episodes will be removed from streaming services Amazon Prime and Hulu, as well as purchase platforms.
They include a live episode with guest star Jon Hamm in series six.
He appeared in a wig and blackface, part of a spoof of an old US radio and TV show titled Amos ‘n’ Andy.
Two episodes featured Jane Krakowski’s character Jenna, one from series three, Believe in the Stars, and the other from series five, called Christmas Attack Zone.
The fourth and final episode being pulled by the studio is the East Coast version of season five’s Live Show, the first live episode of 30 Rock.
News of their removal comes as many content platforms are re-evaluating their offerings following mass protests against racism and police brutality after the death of George Floyd in police custody.
Meanwhile, Matt Lucas and David Walliams apologized for their use of blackface as two of their series, Little Britain and Come Fly With Me, were removed from circulation.
