NCIS (series)

NCIS is a police procedural drama television series, revolving around a fictional team of special agents from the Naval Criminal Investigative Service, which conducts criminal investigations involving active or retired members of the United States Navy and Marine Corps.
The show is set in Washington D.C. and takes place throughout the Capital Metro area and surrounding areas in Maryland and Virginia with some cases even taking place overseas in Afghanistan or Iraq although in real life, the NCIS series is in fact filmed in and around California with primary filming occurring at the Valencia Studios in Santa Clarita, Southern California where JAG, NCIS's parent series was filmed.
==Naming of the show==
Before the launch of the first season, advertisements on CBS called the show as "Naval CIS" and 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, in order to attract new viewers (particularly those of JAG), who might not know the NCIS abbreviation and also 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 and that is the name it carries to this day.
==Production==
The concept of NCIS and its characters were originally introduced in two episodes of NCIS's parent series, "JAG", the JAG Season 8 episodes, Ice Queen (episode) which aired on April 22, 2003 and Meltdown (episode) which aired on April 29, 2003.
Five months later, on September 23, 2003, NCIS premiered as a solo series with its series premiere episode, Yankee White (episode). Donald P. Bellisario and Don McGill served as NCIS's creators and executive producers, the two men also responsible for creating and producing JAG. During NCIS Season 1, the show was known as "Navy NCIS" but it was later dropped from the title and renamed "NCIS".
In the NCIS Season 2 episode, Lt. Jane Doe (episode), NCIS began showing two second long black-and-white clips known as Foofs. These clips are shown at the beginning of every segment depicting the last two seconds of that segment, a segment being the 5–6 portions of the show meant to be separated by commercials. 
In the season three premiere, "Kill Ari (Part I)", a freeze-frame shot or Foof was also used with the very end of most episodes turned into a freeze frame as well.
On April and May 2009, "Legend Part 1" and "Legend Part 2" both aired as part of NCIS Season 6. These two backdoor pilot episodes later resulted in the first ever NCIS spin-off series titled NCIS: Los Angeles starring Chris O'Donnell and LL Cool J with NCIS: Los Angeles ending after fourteen seasons in May 2023.
Six years later, in March and April 2014, "Crescent City" and "Crescent City Part 2" both aired as part of NCIS Season 11. These two backdoor pilot episodes later resulted in the creation of the second NCIS spin-off series, NCIS: New Orleans starring Scott Bakula, Lucas Black, Zoe McLellan and CCH Pounder. NCIS: New Orleans came to an end in May 2021 after seven seasons.
On September 2021, NCIS: Hawaii premiered. 
In 2011, NCIS was voted as America's most favorite show and finished its tenth season as the most-watched television series in the U.S. during the 2012–13 TV season.
On April 15, 2021, NCIS was renewed for Season 19 and premiered on September 20, 2021 before concluding in May 2022 with NCIS Season 20's first episode airing for the first time on Monday September 19, 2022.
On February 21, 2023, NCIS was renewed for a twenty-first season, which premiered on February 12, 2024.
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 twenty-second season.
On April 26, 2024, it was revealed that CBS had cancelled NCIS: Hawaii after three seasons.
NCIS is the first member of the NCIS franchise that consists of JAG, NCIS, NCIS: Los Angeles, NCIS: New Orleans, NCIS: Hawaii NCIS: Origins. 
It is the second longest-running scripted non-animated U.S. primetime TV series currently airing, surpassed only by Law & Order: Special Victims Unit (1999–present), and is the 15th longest-running scripted U.S. primetime TV series overall.

Following Abby's resignation from NCIS, Gibbs hires Kasie in "Fallout" to fill in for her temporarily until he finds a permanent replacement, which she agrees to do with Abby's blessing. However, this slightly unsettles the rest of the members of Gibbs's team, who are still trying to cope with Abby's departure. Kasie becomes the permanent replacement forensics specialist in Season 16.
*Leon Vance (Rocky Carroll) - The current Director for NCIS who originally served as an Assistant Director for NCIS. In the aftermath of the murder of his predecessor, Director Jennifer Shepard, Vance was promoted to the role of Director of NCIS which he continues to hold to this day.

===Former===
*Leroy Jethro Gibbs (Mark Harmon) - A former Gunnery Sergeant with the United States Marine Corps, Gibbs is the Supervisory Special Agent of the main NCIS Major Case Response Team. During his time as a Marine, Gibbs served as a Marine sniper and originally had a happy family until his first wife, Shannon and their young daughter, Kelly were murdered by an assassin with ties to a Mexican drug lord due to the fact that the assassin had shot the NIS agent assigned to guard Shannon and Kelly which caused a crash that later cost the two their lives. As this happened, Gibbs was serving in Desert Storm and after learning of their deaths, was so consumed by grief and revenge that he later headed to Mexico to exact his revenge against the drug lord which he did by killing the other man after shooting him through the head, unaware that the drug lord had two children. Gibbs later returned to the U.S and kept the crime concealed for nearly twenty years until it returned with a vengeance in May 2010. After leaving the Marines with the rank of Gunnery Sergeant, Gibbs joined NCIS when it was known as NIS as a Junior Agent and was known by his boss as "probie", which his former boss still calls him. Gibbs then rose through the ranks until he gained full leadership of the Major Case Response Team which he holds to this day. Gibbs is seen as somewhat of a fatherly figure to Abby, Kate, and later to Ziva. Due to his senior status at NCIS, he has also carried out tasks at a higher level, such as becoming a temporary acting director for the entire agency and point man for the agency during a major crisis such as the Harper Dearing terrorist attacks. After being shot by teenager Luke Harris in the Season 12 finale episode, "Neverland", Gibbs ultimately survived thanks to the effects of Navy doctor Dr. Cyril Taft with Gibbs returning to work months later and during the Season 13 premiere episode, "Stop the Bleeding". Gibbs later resigns and decides to stay in Naktok Bay, feeling a sense of peace he hadn't felt since before the deaths of his wife and daughter, and bids an emotional farewell to McGee.
*Abigail Sciuto (Pauley Perrette) - The Chief Forensic Scientist with the NCIS Major Case Response Team, Abby wears Gothic-styled clothing and is addicted to the fictional beverage, Caf Pow. Later resigns from NCIS for good in the Season 15 episode, Two Steps Back (episode).
*Caitlin Todd (Sasha Alexander) - An NCIS Special Agent who prior to joining NCIS worked as an agent with the Secret Service and who was also assigned to the Presidential Protection Detail on board Air Force. In the aftermath of a case where a terrorist attempted to kill the President of the United States, Kate permanently resigned from the Secret Service and almost immediately, joined NCIS where she stayed for a year and a half while also serving as Tony DiNozzo's partner. Kate's potential career as an NCIS Special Agent came to an abrupt as well as tragic end when she was shot in the head and killed by terrorist, Ari Haswari in the last few minutes of the NCIS Season 2 finale episode, Twilight.
*Jennifer Shepard (Lauren Holly) - A former NCIS Special Agent, Shepard became the new Director in the aftermath of her predecessor, Tom Morrow resigning. She held the position for three years before dying from injuries sustained in a gunfight in the Season 5 finale episode, "Judgment Day Part 1".
*Ziva David (Cote de Pablo) - A former officer associated with Mossad, Ziva joined the NCIS team, replacing her predecessor, Kate Todd. At the time, Ziva was simply a Liaison Officer between NCIS and Mossad. Ziva is also responsible for killing Ari Haswari, a terrorist who is Ziva's own half-brother and who also killed Ziva's predecessor, Kate. At the end of Season 6, Ziva resigned from NCIS and stayed in Israel although she was later captured in Somalia and tortured by tourists. In the Season 7 premiere episode, "Truth or Consequences", Gibbs, McGee and Tony rescued her. Following her recovery, Ziva resigned from Mossad for good and was eventually given the right to become a probationary NCIS agent. Two or three years later, Ziva, having since become a citizen of the United States, also became a fully-fledged NCIS Special Agent too. She later resigned in the Season 10 finale episode, "Damned If You Do" and despite Tony's attempts to convince her otherwise, chose to stay in Israel with the Season 11 episode, "Past, Present and Future" marking Ziva's final appearance. She was later replaced by Eleanor "Ellie" Bishop. Tragically, three years later, during the NCIS Season 13 finale episode, "Family First", it was believed that Ziva had been killed in a mortar attack. She is revealed to be alive in the season 16 finale when she appears in Gibbs' basement to inform him he is in danger.
*Anthony DiNozzo (Michael Weatherly) - The Senior Special Agent of the NCIS Major Case Response Team, DiNozzo prior to joining NCIS was a homicide Detective in Baltimore. Eventually, after learning that his partner was corrupt, DiNozzo resigned and joined NCIS instead which occurred in 2001. Due to the fact that in Gibbs's absence Tony had a habit of displaying the personality traits associated with Gibbs such as headslapping or demanding that the other members of the team get straight to the point, many saw Tony as a younger version of Gibbs. Tony was also a womanizer and also a fan of movies. Due to his childish behavior, Tony was the one who received most of the headslaps that Gibbs usually dished out. In May 2016, after learning that he'd had a daughter named Tali with Ziva, Tony resigned from the team for good to take care of Tali.
*Alexandra Quinn (Jennifer Esposito)- A Special Agent with the NCIS Major Case Response Team, Quinn originally worked as an instructor at FLETC. She later presumably resigned from the team for good some time prior to September 2017 to take care of her mother, Marie who had developed Alzheimer's.

In the aftermath of NCIS Special Agent Kate Todd's murder, Morrow resigned from his position at NCIS, having been offered a job at the Department of Homeland Security which Morrow accepted. Morrow was later replaced by Jenny Shepard and following Shepard's death by Leon Vance. Morrow later returned in NCIS Season 10, still employed with Homeland Security. He continued to make numerous appearances in NCIS, regularly assisting the team with investigations but was tragically murdered by disgraced CIA agent Trent Kort.
*Michael Franks - Gibbs's mentor and a former NIS agent, Franks took Gibbs under his wing when Gibbs joined NIS (later NCIS) and taught Gibbs everything he knew.

Bell later attempted to kill Mike Franks and Franks' own family to presumably weaken Gibbs but Bell himself was later betrayed and killed by his own second-in-command, Jason Paul Dean on the orders of Paloma Reynosa with Bell's remains being disfigured to hide the cause of death and also the identity of Bell's murderer although NCIS later uncovered the truth.

NCIS has become a top 10 program in its fifth season, with an average of about 15.65 million viewers, despite the WGA strike.
The show is one of the few that has increased in viewership over the last few years as it progresses, as opposed to most shows, which decrease in popularity as they fade, and NCIS has even been able to finish a strong second to American Idol, a time slot seen by many as a "death slot" for most series.
The most watched NCIS episode to date was originally the seventh season episode Reunion (episode) with an audience of 21.37 million although it was later surpassed by the Season 10 episode, Shiva (episode) with 22 million people watching that episode.
