"Roseanne" was canceled by ABC shortly after Barr posted tweets referring to former Obama adviser Valerie Jarrett as the child of the Islamist organization the Muslim Brotherhood and the movie "Planet of the Apes".
Her tweet about Jarrett had prompted others to point out that the tweet was racist, with Barr replying: "Muslims r NOT a race".
The current season of the show finished airing in New Zealand on Three last week and MediaWorks has removed episodes from its ThreeNow service. She then tweeted that she was leaving Twitter.
Roseanne originally aired from 1988 until 1997, telling the story of the working-class Conner family in IL.
Leading the charge was one of the canceled show's producers and stars, Sara Gilbert, who called the original tweet "abhorrent", adding that it didn't reflect the beliefs of the cast or crew.
"I think it is a good first step but I think we need to address everyday racism".
Before the announcement of the cancellation, Roseanne consulting producer and famed writer and comedian Wanda Sykes vowed not to return to the show.
It was not enough, and as the uproar continued Tuesday, ABC made the decision to cancel the show.
Earlier, Barr had also tweeted about billionaire investor and philanthropist George Soros, calling him "a nazi who turned in his fellow Jews 2 be murdered in German concentration camps & stole their wealth".
In response to John Goodman's Dan saying the couple had "missed all the shows about black and Asian families" Barr's character responded: "they're just like us".
Walt Disney Co. CEO Bob Iger also commented on the cancellation, tweeting: "There was only one thing to do here, and that was the right thing". Variety reported in 2017 that Barr was making an estimated $250,000 per episode of Roseanne. "ABC treated them both the same", one user pointed out.
What did Trump say?
The disgraced television star returned to retweet her supporters after an hours-long hiatus where she tweeted, "I apologize". But Barr's provocative utterances, sometimes in the context of her Trump support, made that hard.
She apologized to Jarrett on Tuesday night while continuing to attack her.
