Tucker Carlson Tonight is an American conservative talk show and current affairs program hosted by political commentator Tucker Carlson. The show aired on Fox News from November 14, 2016, to April 21, 2023, replacing On the Record hosted by Greta Van Susteren. Tucker Carlson Tonight included political commentary, monologues, interviews, and analysis, sharing some similarities with On the Record. Guest hosts for the program included Will Cain, Sean Duffy, Tulsi Gabbard and Brian Kilmeade.
The show is presented in a populist format. Tucker Carlson Tonight employed a minute-by-minute viewership rating system, a change brought about by Ron Mitchell, the former senior producer for The O'Reilly Factor. During its run, the show garnered significant attention amid several controversies. In July 2020, Tucker Carlson Tonight became the highest-rated primetime program across all of cable news; its dominance in the time slot ended only after the program's abrupt cancellation.
On April 24, 2023, Fox News announced that Tucker Carlson had departed the network. The timeslot was rebranded as Fox News Tonight and filled by an interim rotation of personalities.
