Ncis

NCIS is a long-running television procedural drama series broadcast on CBS that originally premiered in 2003. The flagship show centers on a squad of naval crime investigators handling high-stakes cases and security threats. Over more than two decades, the series has anchored an expanded television franchise that includes various regional offshoots and spinoffs.

Recent developments surrounding the franchise highlight major cast returns and universe expansions ahead of the fall 2026 television season. Actor Michael Weatherly, who starred as special agent Anthony "Tony" DiNozzo for 13 seasons before departing in 2016, is returning to the flagship series for its season 24 premiere on October 6. His character steps in as a visitor to help investigate a major security breach following the events of season 23.

Simultaneously, the franchise is expanding with the launch of the spinoff series NCIS: New York, which debuts on October 6 on CBS. Starring and executive produced by LL Cool J alongside showrunner Byron Balasco, the new East Coast unit will feature crossover guest appearances, including original series cast member Brian Dietzen reprising his role as Dr. Jimmy Palmer.
