Development
The origins of the series go back to the Television Critics Association summer 2016 press tour, where Wolf revealed plans for a crime drama series, placed in New York and set in the world of the FBI. Wolf's original plan was to introduce it on the NBC network as a planned spin-off to his New York crime drama Law & Order: Special Victims Unit, where it was intended to introduce an FBI agent character, but NBC ultimately did not go through with it and the idea was later put on hold for different reasons. It's Wolf's first drama series to launch on a network other than NBC in 15 years. CBS officially picked up the series on September 20, 2017. The series is produced by CBS Television Studios and Universal Television.
