NCIS is an American police procedural television series, revolving around a fictional team of special agents from the Naval Criminal Investigative Service combining elements of the military drama, police procedural genres, and comedy. The concept and characters were initially introduced in two episodes of the CBS series JAG (season eight episodes 20 and 21: "Ice Queen" and "Meltdown"). A spin-off from JAG, the series premiered on September 23, 2003, on CBS. To date, it has entered into the 20th full season and has gone into broadcast syndication on the USA Network. Donald P. Bellisario and Don McGill are co-creators and executive producers of the premiere member of the NCIS franchise. As of 2022 [update] , NCIS is the third-longest-running scripted, non-animated U.S. primetime TV series currently airing, surpassed only by Law & Order: Special Victims Unit (1999–present) and Law & Order (1990–2010; 2022–present); it is the seventh-longest running scripted U.S. primetime TV series overall.
The series originally had the partly redundant title Navy NCIS: Naval Criminal Investigative Service; this was later shortened to NCIS: Naval Criminal Investigative Service and then to NCIS. In season six, a two-part episode led to a spin-off series, NCIS: Los Angeles . A two-part episode during the 11th season led to a second spin-off series, NCIS: New Orleans . Though initially slow in the ratings, barely cracking the top 30 in the first two seasons, the third season showed progress, consistently ranking in the top 20, and by its sixth season, it became a top-five hit, having remained there since. In 2011, NCIS was voted America's favorite television show in an online Harris Poll. The series finished its 10th season as the most-watched television series in the U.S. during the 2012–13 network television season. NCIS is on its 20th season. On February 21, 2023, NCIS was renewed for a 21st season.

Supervisory Special Agent Alden Parker, a former FBI special agent, now leads the team.
Only David McCallum as Dr. Donald "Ducky" Mallard has been credited to every episode since the show's inception.

Before the launch of the first season, advertisements on CBS identified the show as "Naval CIS". By the time of the launch of the first episode, NCIS was airing under the name Navy NCIS, the name it held for the entire first season. Since the "N" in NCIS stands for "Naval", the name "Navy NCIS" was redundant. The decision to use this name was reportedly made by CBS, over the objections of Bellisario,  who preferred the old title because he felt it would:
In 2011, NCIS was voted America's favorite television show in an online Harris poll.  NCIS finished its 10th season as the most-watched television series in the U.S. during the 2012–13 network television season.  Diona Reasonover joined the main cast in season 16,  following the departures of Duane Henry and Pauley Perrette.  NCIS was renewed for a seventeenth season on April 11, 2019,  which premiered on September 24, 2019,  and for an eighteenth season in May 2020. The season premiered on November 17, 2020. 
From the season two episode "Lt. Jane Doe" onwards, the series began showing two-second-long black-and-white clips. These clips (called "phoofs")  are shown at the beginning of every segment depicting the last two seconds of that segment, a segment being the five or six portions of the show meant to be separated by commercials. Additionally, starting with the season three premiere, "Kill Ari (Part I)," a freeze-frame shot was also used at the very end of most episodes as well.
It was reported in May 2007 that Donald P. Bellisario would be stepping down from the show.  Due to a disagreement with series star Mark Harmon, Bellisario's duties as showrunner/head writer were to be given to long-time show collaborators, including co-executive producer Chas. Floyd Johnson and Shane Brennan, with Bellisario retaining his title as executive producer.  In fall 2009,[ clarification needed ] Gary Glasberg joined the crew and became the new "day-to-day" runner of NCIS because Shane Brennan had to focus on his new show, the spin-off NCIS: Los Angeles .  On September 28, 2016, Glasberg died in his sleep at the age of 50.
