NCIS (promoted as Navy NCIS in season one), aka Navy NCIS: Naval Criminal Investigative Service or NCIS: Naval Criminal Investigative Service, is an American police procedural television series revolving around a fictional team of special agents from the Naval Criminal Investigative Service, which conducts criminal investigations involving the U.S. Navy and Marine Corps.

The concept and characters were initially introduced in a two-part episode of the CBS series JAG (episodes 8.20 and 8.21). The show, a spin-off from JAG, premiered on September 23, 2003 on CBS and, to date, has aired six full seasons. Donald Bellisario, who created JAG, as well as the well-known series' Magnum, P.I. and Quantum Leap, is co-creator and executive producer of NCIS. NCIS was originally referred to as "Navy NCIS", however "Navy" was later dropped as it was redundant. NCIS will return for a seventh season in the second half of 2009, Tuesdays at 8pm and will be followed by its spin-off series NCIS: Los Angeles at 9pm on CBS.[2]

[edit] Premise
NCIS is a television series that follows a fictional team of Naval Criminal Investigative Service Major Case Response Team (MCRT) special agents, headquartered at the Washington Navy Yard in Washington, D.C. It is described by the actors and producers (on special features on DVD releases in the USA) as being distinguished by its comedy elements, ensemble acting and character-driven plots.

NCIS is the primary law enforcement and counter-intelligence arm of the United States Department of the Navy, which includes the United States Marine Corps. NCIS investigates all major criminal offenses (felonies), those crimes punishable under the Uniform Code of Military Justice by confinement of more than one year, within the Department of the Navy. This can be seen when the “NCIS team” is frequently assigned to high-profile cases such as the death of the President's military aide, a bomb situation on a U.S. Navy warship, the death of a celebrity on a reality show set on a USMC base, terrorist threats, and kidnappings.

The “NCIS team” is led by Special Agent Leroy Jethro Gibbs (Mark Harmon). Gibbs’ team is composed of Special Agent and Senior Field Agent Anthony DiNozzo (Michael Weatherly), Special Agent Timothy McGee (Sean Murray) and Mossad Liaison Officer Ziva David (Cote de Pablo), who replaced Caitlin 'Kate' Todd (Sasha Alexander) when she was shot by Ari Haswari (Rudolf Martin) at the end of season two. Ari himself was then killed by his half-sister Ziva in the beginning of season three. The team is assisted in their investigations by Chief Medical Examiner Donald "Ducky" Mallard (David McCallum), Forensic Specialist Abby Sciuto (Pauley Perrette) and Assistant Medical Examiner Jimmy Palmer (Brian Dietzen).

NCIS is currently led by Director Leon Vance (Rocky Carroll). The first Director seen in the series, Thomas Morrow, (Alan Dale) left after a promotion to Deputy Director of DHS. Jenny Shepard (Lauren Holly) was appointed Director after Morrow; she was killed in a shootout at the end of the fifth season.

Prior to 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 technically redundant (an example of RAS syndrome). The decision to use this name was reportedly made by CBS, over the objections of Bellisario, in order to:

Attract new viewers (particularly those of JAG), who might not know the NCIS abbreviation.
Disambiguate between NCIS and the similarly-themed and similarly-spelled CBS series CSI and its spinoffs. (The original title, for instance, was often misquoted as "Navy CSI").
After its successful first season, the name of the series was shortened to NCIS.

Filming location
NCIS is set in the Washington D.C. area but is filmed in Santa Clarita, California.[4]

The sound stages are in Santa Clarita, California
The series is shot throughout southern California

Crew changes
It was reported in May 2007 that Donald Bellisario would be stepping down from the show.[5] Due to a disagreement with series star Mark Harmon, Bellisario's duties as show runner/head writer were to be tasked to long-time show collaborators, including co-executive producer Chas. Floyd Johnson and Shane Brennan, with Bellisario retaining his title as Executive Producer.[6]

NCIS became a top 10 program in its fifth season, averaging 15.65 million viewers, despite a WGA strike. Notably, the show is one of the few that has actually increased in viewership as it progresses, as opposed to most shows which decrease in popularity as they fade, and has even been able to finish a strong second to Fox's American Idol, a time slot seen by many as a "death slot" for most series.

NCIS delivered its largest audience ever to date, in the sixth season episode "Silent Night", soaring to 19.86 million viewers. It won its time slot in households (12.0), viewers (19.94m), adults 25–54 (5.8) and second in adults 18–49 (4.0; behind NBC's season finale of The Biggest Loser). NCIS posted its best ever delivery in households and viewers, best adults 25–54 performance since October 16, 2007 and matched season high adults 18–49 delivery.[11]

Its second highest rated episode (Jan. 2009): households (11.6), viewers (19.10m), adults 25–54 (5.6) and second in adults 18–49 (3.8).[citation needed]
