(CNN) ABC canceled its hit sitcom "Roseanne" on Tuesday after the show's biggest star, Roseanne Barr, went on a racist Twitter rant.
"Roseanne's Twitter statement is abhorrent, repugnant and inconsistent with our values, and we have decided to cancel her show," ABC Entertainment president Channing Dungey said in a statement.
Disney CEO Bob Iger added on Twitter that "There was only one thing to do here, and that was the right thing."
The cancellation was a shock in Hollywood. The revival of "Roseanne" premiered to huge ratings just three months ago.
Pre-production was already underway on a second season, which was scheduled for Tuesdays at 8 p.m. this fall.
When Barr's racist tweets caught fire early Tuesday, ABC went silent for several hours.
When asked why ABC ultimately decided to cancel the sitcom, a Disney source said, "It's a question of right and wrong. And it's a question of our company's values."
Reactions to the decision were overwhelming and largely positive.
