When NCIS premiered more than 20 years ago, few could have predicted the cultural impact it would eventually achieve. Now, as the show prepares to air its 500th episode, it stands as one of the most enduring series in television history.
Over the years, the show has seen many cast changes and dramatic storylines, from the shocking death of Special Agent Kate Todd to the departure of longtime fan-favorite characters.
Still, the core formula — compelling cases mixed with character-driven storytelling — has kept audiences invested for more than two decades.
Today’s cast, including Gary Cole, Wilmer Valderrama, Sean Murray, and Katrina Law, continues to carry the legacy forward as the franchise celebrates another milestone moment.
