The NCIS family continues to expand, with a total of seven existing or former shows and one more in development as of 2025. Many fans may be surprised to learn that the naval intelligence-based franchise actually began with JAG, not NCIS. Originally airing on NBC in 1995, JAG followed military lawyers in the Department of the Navy’s Office of the Judge Advocate General as they handled criminal cases under the code of military justice. After NBC canceled the show after one season, CBS picked it up and continued its success.
The original drama, starring David James Elliott and Catherine Bell, paved the way for the introduction of Jethro Gibbs, played by Mark Harmon, and his team in the eighth season finale of JAG in 2003. The positive reception to this backdoor pilot led CBS to order a full first season of NCIS, which premiered the following year in September.
Fast forward more than 30 years since the debut of JAG, and the NCIS franchise shows no signs of slowing down. With multiple spinoffs and a dedicated fan base, the franchise continues to captivate audiences with its thrilling naval intelligence stories and compelling characters.
Stay tuned for more updates on the expanding NCIS universe, as new shows are in the works to keep fans entertained and engaged. Dive into the world of naval intelligence and military justice with the NCIS franchise, where every episode brings new challenges and adventures for the dedicated team of agents and lawyers.
