US reality show 'The Activist' backtracks after uproar

"The Activist," whose launch was announced this week, was to be broadcast on American network CBS in October and co-produced by non-governmental organisation Global Citizen, with celebrity hosts such as the singer Usher, actress Priyanka Chopra and dancer Julianne Hough.

But no sooner had they unveiled plans for the "groundbreaking" programming they insisted would inspire real change, the producers announced they were dramatically reformatting the show, jettisoning the competitive activism-themed contests and switching to a one-time documentary rather than a multi-episode series.

"We got it wrong," Global Citizen said in an online apology. "Global activism centers on collaboration and cooperation, not competition."

CBS had said the audience of the original show would follow the adventures of "six activists from around the world working to bring meaningful change to one of three urgent universal causes: health, education and the environment."

The finale was to take place at the Group of 20 summit of world leaders in Rome in late October.

But CBS said they recognised that format "distracts from the vital work these incredible activists do in their communities every day," and that the concept would be reimagined into a non-competitive prime-time special.

"I have been moved by the power of your voices over the past week," Chopra told her 27 million Twitter followers.

"The show got it wrong, and I'm sorry that my participation in it disappointed many of you."

Hough, posting on Instagram, said she recognized that for some the show idea "felt like the Oppression Olympics" and disrespected activists who have faced abuse or even have been killed fighting for their causes.
