NCIS Celebrates 500 Episodes

On March 24, 2026, NCIS aired its 500th episode, marking a significant milestone in television history. The series, created by Donald Bellisario, has captivated audiences for years, with a peak viewership of 9.7 million during the 2023-24 season, although this number dropped to 7.85 million in the following season.

Originally spun off from the series JAG, which concluded in May 2005, NCIS has become a cornerstone of American television. The show focuses on special agents from the Naval Criminal Investigative Service, with Mark Harmon leading the team as Leroy Jethro Gibbs until his departure.

Over its long run, NCIS has received 3 Emmy nominations but has yet to secure a win. Despite this, the series has spawned 5 domestic spinoff series and one international spinoff, NCIS: Sydney, and has been licensed in over 200 international markets.

The late David McCallum, who portrayed Dr. Donald ‘Ducky’ Mallard from the first season until his death in 2023, was a beloved character among fans. His contributions, alongside the ensemble cast, have been pivotal in the show’s enduring success.

Reflecting on the show’s impact, Donald Bellisario remarked, “I have a very strange way of writing,” highlighting the unique storytelling approach that has kept audiences engaged.

For five consecutive years, NCIS was the highest-rated broadcast TV series, a testament to its popularity and the loyalty of its fanbase. The show’s ability to blend drama, humor, and action has resonated with viewers, making it a staple in many households.

As the series continues to evolve, observers are keen to see how it will adapt to changing viewer preferences and the competitive television landscape. Details remain unconfirmed regarding future storylines and cast changes.
