On March 24, 2026, NCIS aired its landmark 500th episode, celebrating over two decades of captivating audiences with its thrilling storylines. The series, created by Donald Bellisario, has become a staple of American television, showcasing the dedicated work of special agents from the Naval Criminal Investigative Service.
Originally led by Mark Harmon as Leroy Jethro Gibbs, NCIS has garnered a loyal fan base, peaking at a viewership of 9.7 million during the 2023-24 season. However, the following season saw a decline, with viewership dropping to 7.85 million. Despite this, the show remains a significant player in the television landscape.
Over the years, NCIS has received three Emmy nominations but has yet to secure a win. Its influence extends beyond the original series, with five domestic spinoff series and one international spinoff, NCIS: Sydney, licensed in more than 200 international markets.
The series has also been marked by the memorable performance of David McCallum, who played Dr. Donald ‘Ducky’ Mallard from the very first season until his passing in 2023. His character was beloved by fans and contributed significantly to the show’s charm.
Reflecting on the show’s journey, Bellisario once remarked, “I have a very strange way of writing,” hinting at the unique storytelling that has kept audiences engaged for years. The series has been recognized as the highest-rated broadcast TV series for five consecutive years, a testament to its enduring popularity.
As the community celebrates this milestone, fans and cast alike look forward to what the future holds for NCIS.
