NBC picked up Brooklyn Nine-Nine about 30 hours after Fox canceled it.
Fox announced the cancellation on May 10, 2018, after five seasons. NBC’s announcement followed on May 11, making the rescue one of television’s fastest high-profile reversals. The “30 hours” figure is the commonly reported interval between the two announcements, not a claim that every negotiation was completed from scratch in exactly thirty clocked hours.
The speed was helped by the show’s existing production team, cast, and studio arrangements. It was also fueled by an unusually visible fan campaign, which spread across social media after Fox’s decision. NBC had previously passed on the series before Fox aired it, making the eventual pickup especially notable.
NBC initially ordered a 13-episode sixth season, later expanding it to 18 episodes. Season six premiered on January 10, 2019, and the show continued through an eighth and final season.
