Roseanne has been cancelled just three months into its revival run – and despite massive ratings – following a racist and conspiracy-laden tweetstorm from the show's star.

Roseanne Barr, known for her often outrageous statements and performances, acknowledged she went too far when she railed against former Obama-advisor Valerie Jarrett, saying she was "a product of the Muslim Brotherhood and Planet of the Apes". It was too much for America's ABC network, which pulled the plug. Australia's Network Ten has also axed the show. 

The program and its titular star have been the subject of fascination by media and American cultural commentators (as well as President Trump) following their ratings success and amidst allegations of a failure by Hollywood to properly represent "Trump's America" or red-state voters in popular entertainment.

Barr's now-deleted tweet came on the same day US Starbucks stores shut down for racial sensitivity training nationwide.
