The NCIS family just keeps growing — with seven existing or former shows and one more on the way as of 2025.
While many fans might think the naval intelligence-based franchise began with NCIS, that’s not the case. The flagship NCIS show was actually JAG, which debuted on NBC in 1995.

The series followed military lawyers in the Department of the Navy’s Office of the Judge Advocate General who could prosecute and defend criminal cases under the code of military justice. NBC canceled the show after one season, but CBS picked it up.
The original drama, which starred David James Elliott and Catherine Bell, introduced Jethro Gibbs (Mark Harmon) and his team in the eighth season finale in 2003. The excitement around the backdoor pilot led to CBS ordering a full first season of NCIS, which premiered the following September.
More than 25 years after JAG started, the NCIS franchise is still alive and well.

The original show ran from 1995 to 2005 with a total 227 episodes throughout its 10 seasons.

The first spinoff launched in 2003 and ran for 19 seasons with Harmon still at the helm as Gibbs. The actor exited the series in 2021 following an appearance on season 19’s episode “Great Wide Open.” The drama returned for season 20 in September 2022 with Gary Cole’s Agent Alden Parker stepping in as the new head of the team.
Season 21 was initially slated to begin in fall 2023 but was pushed back because of the WGA and SAG-AFTRA strikes. The new season finally premiered in February 2024. Season 22 kicked off in October 2024.
