Fable, a San Francisco company, is launching Showrunner, an AI platform that allows users to create their own TV shows by writing prompts. Led by CEO Edward Saatchi and veterans from Oculus, Pixar, and AI startups, Fable has pivoted from virtual reality to AI. Showrunner can generate TV episodes from prompts, with content ranging from 2 to 16 minutes. The platform includes shows like "Exit Valley" and "United Flavors of America," and aims to democratize TV production. Users can potentially earn IMDB credits and revenue sharing for successful contributions.
