The TV show "NCIS" has brought significant awareness to the real Naval Criminal Investigative Service (NCIS), which is a small civilian organization responsible for investigating felony crimes, preventing terrorism, and protecting secrets for the Navy and Marine Corps. The conference room in the show features what appears to be a series of signatures on the NCIS seal. These signatures are actually those of real-life NCIS agents, as revealed by actress Pauley Perrette, who played Abby Sciuto. This tribute not only holds honorary significance but also signifies that the actual NCIS agents have given their approval to the show. The fact that the show has gained popularity and receives positive recognition from real NCIS agents indicates its accurate portrayal of the agency. With the show being renewed for its 19th season and Mark Harmon reprising his role as Special Agent Leroy Gibbs, any rumors about his departure suggest that the show may face a decline in ratings without him.
