Though the ratings have declined, NCIS has remained one of CBS’ top-rated TV shows. Still, it’s been around since 2003 (a spin-off of JAG) and all shows have to end sometime. Could this be the CBS show’s last or, is it all but guaranteed to come back for the 2020-21 season? Will NCIS be cancelled or renewed for season 18? Stay tuned. *Status update below.

An action-drama series, the NCIS TV show stars Mark Harmon, Sean Murray, Emily Wickersham, Wilmer Valderrama, Maria Bello, Brian Dietzen, Diona Reasonover, Rocky Carroll, and David McCallum. On the series, NCIS Special Agent Leroy Jethro Gibbs (Harmon), a former Marine gunnery sergeant whose skills as an investigator are unmatched, leads a highly skilled and colorful group of professionals who investigate crimes that have connections to the Navy or Marine Corps.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly in the 18-49 demo), the better the chances for survival.
