The Journey to 500 Episodes
On March 17, 2026, CBS's long-running procedural drama "NCIS" aired its 500th episode, titled "All Good Things." This milestone places "NCIS" among the longest-running scripted, live-action American prime-time series, following only "Law & Order: Special Victims Unit" and "Law & Order." The show, which premiered on September 23, 2003, was initially introduced as a backdoor pilot during the series "JAG." It features a team of special agents from the Naval Criminal Investigative Service, led by Leroy Jethro Gibbs, portrayed by Mark Harmon.
Despite a slow start, ranking 26th in its inaugural season, "NCIS" gained momentum, becoming a top-rated show by its sixth season and ultimately the number one broadcast series by its tenth season. The series has since expanded into a global franchise, with numerous spinoffs, including "NCIS: Los Angeles," "NCIS: New Orleans," "NCIS: Hawaii," and the recent "NCIS: Sydney."
Key Changes and Character Evolution
The 500th episode marks a significant turning point for "NCIS," as it explores the future of the team amidst threats to its existence. The episode picks up from a cliffhanger where NCIS director Leon Vance reveals that the agency is being shut down. Showrunner Steven D. Binder emphasized the need for a fresh approach while maintaining the show's core essence. The episode revisits a case from the show's second episode, connecting past and present narratives.
The series has seen numerous cast changes over its 20-year run. Harmon, who stepped down in 2021, remains an executive producer, while new characters like Alden Parker, played by Gary Cole, have been introduced. The evolution of characters is evident, with actors like Wilmer Valderrama and Diona Reasonover discussing how their roles adapt to contemporary themes, including representation of queer characters.
