NBC revived Brooklyn Nine-Nine after Fox canceled it. Fox announced the cancellation on May 10, 2018, after the comedy had completed five seasons, and NBC officially picked it up the next day.
The rescue was unusually fast. TBS, Hulu, Netflix, and other services were reportedly considered, while fans mounted a major social-media campaign urging another network to save the show. NBC ultimately ordered a sixth season, initially set for 13 episodes and later expanded to 18.
The move also changed the show's broadcast history. Seasons one through five aired on Fox, while season six premiered on NBC on January 10, 2019. NBC continued the series through its seventh season and its 10-episode eighth and final season, which ended in 2021.
A common mix-up is TBS, because it had shown interest in acquiring the series and was associated with other rescued comedies. It did not become Brooklyn Nine-Nine's new network; NBC did.
