# NCIS (TV series)

NCIS is an American military police procedural series and the first show within the NCIS franchise. The series revolves around a fictional team of special agents from the Naval Criminal Investigative Service (NCIS). The concept and characters were initially introduced with two episodes of the CBS series JAG (season eight episodes 20 and 21: "Ice Queen" and "Meltdown"); as a spin-off from JAG, the series premiered on September 23, 2003, on CBS. To date, it has entered into the 21st 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, NCIS is the third-longest-running scripted, live-action American prime-time 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 American prime-time 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. Another two-part episode, during the 11th season, led to a second spin-off series, NCIS: New Orleans.
Though reception was initially tepid, with ratings barely cracking the top 30 during the first two seasons, the third season showed progress and consistently ranked in the top 20. In 2011, NCIS was voted "America's favorite television show" in an online Harris Poll. At the end of its 10th season, it was the most-watched television series in the U.S. during the 2012–13 network television season. NCIS also surpassed Gunsmoke's record for longest-running scripted primetime television series to air on CBS.
On January 5, 2024, it was announced that the prequel, NCIS: Origins, will be aired during the 2024–25 season, as another spin-off series; a second spin-off, NCIS: Tony & Ziva, was announced on February 28, 2024, as a series exclusive to Paramount+. On April 9, 2024, NCIS was renewed for a 22nd season, which premiered on October 14, 2024. In February 2025, it was renewed for season 23.

## Premise

NCIS details the experiences and stories of a team of special agents working for the NCIS. The team, called the Major Case Response Team (MCRT) primarily responds to high-visibility crimes; NCIS is the main federal law enforcement agency of the United States Department of the Navy, investigating criminal activities (e.g. deaths, force protection, treason, etc.) related to the United States Navy and Marine Corps (USMC), and their associated branches of government.
In the series, the NCIS is based at the Washington Navy Yard in Washington, D.C., where it was previously led by Supervisory Special Agent Leroy Jethro Gibbs, a former USMC Gunnery Sergeant/Scout Sniper and a skilled investigator, until his suspension late in season 18. Supervisory Special Agent Alden Parker (a former FBI special agent) now leads the team, following his appointment early in season 19.

## Production
### Title

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:
* Attract new viewers (particularly those of JAG), who might not know the NCIS abbreviation
* Distinguish between NCIS and the similarly themed and similarly spelled CBS series CSI and its spinoffs. (The original title, for instance, was often misquoted and parodied as "Navy CSI", something the show itself referenced in the first episode.)

### Development

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.
On January 8, 2025, it was announced that NCIS would suspend production due to the wildfires in the Southern California region, where the show is filmed. Production was resumed January 13.

### Flair

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.

### Crew changes

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, 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.

## Franchise

NCIS has produced six spin-offs: NCIS: Los Angeles (2009–2023), NCIS: New Orleans (2014–2021), NCIS: Hawaiʻi (2021–2024), NCIS: Sydney (2023–), NCIS: Origins (2024–) and NCIS: Tony & Ziva (2024–).

### NCIS: Los Angeles

In November 2008, it was reported that a first spin-off series set in Los Angeles would be introduced with a two-part backdoor pilot during the sixth season of NCIS. The episode title "Legend (Part I)" and "Legend (Part II)", airing on April 28, 2009, and May 5, 2009. In May 2009, CBS picked up an NCIS spin-off series with the title NCIS: Los Angeles.
The series stars Chris O'Donnell as Special Agent G. Callen, LL Cool J as Special Agent Sam Hanna, Louise Lombard as Special Agent Lara Macy, Peter Cambor as Operational Psychologist Nate Getz, and Daniela Ruah as Special Agent Kensi Blye. Following the official pick-up by CBS, it was confirmed that Lombard would not continue her role as Special Agent Lara Macy. Linda Hunt and Adam Jamal Craig were added the cast as OSP Manager Henrietta Lange and Special Agent Dom Vail respectively. Craig, would not be returning for second season and was replaced by Eric Christian Olsen as Marty Deeks promoted to series regular.
Characters from NCIS have appeared in the spin-off. Rocky Carroll portrayed Leon Vance in a recurring role, and Pauley Perrette portrayed Abby Sciuto, with a guest appearance in the season 1 episodes "Killshot" and "Random on Purpose".
NCIS: Los Angeles was created by Shane Brennan. In April 2011, NCIS creator Donald Bellisario sued CBS over NCIS: Los Angeles because of his contract which gave him "first opportunity" to develop a spin-off or sequel; the lawsuit was dismissed by a judge in June 2012. However, discussions continued between CBS and Bellisario, and in January 2013 the dispute was settled outside of court a week before it was set to go to trial; the terms of the agreement were not disclosed but were described as being amicable.

### NCIS: New Orleans

In September 2013, it was reported that a second spin-off series set in New Orleans would be introduced with a two-part backdoor pilot during the eleventh season of NCIS. The episode title "Crescent City (Part I)" and "Crescent City (Part II)". The episodes were filmed in February 2014, and aired on March 25, 2014, and April 1, 2014. NCIS star Mark Harmon and showrunner Gary Glasberg are the executive producers of the series. Glasberg discussed the idea of the episode with Harmon, who said "That's more than a sweeps episode" (meaning an episode with provocative subject manner and top appeal for television ratings). The premise for the episodes are, according to Glasberg, "all about this tiny little NCIS office that's down [in New Orleans], and the kind of cases that they come across". In May 2014, CBS picked up an NCIS second spin-off series with the title NCIS: New Orleans.
The series stars Scott Bakula as Special Agent Dwayne Cassius Pride, Lucas Black as Special Agent Christopher LaSalle, Zoe McLellan as Special Agent Meredith "Merri" Brody, Rob Kerkovich as Sebastian Lund, and CCH Pounder as Dr. Loretta Wade.
