Question: What word was dropped from the title of the show "NCIS"?

Candidate passages:
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 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.
Disambiguate between NCIS and the similarly themed and similarly spelled CBS series "" 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).
From the season two episode, "Lt. Jane Doe" onwards, the series began using what fans of the show have named 'foofs' – black-and-white 'teases' of something to occur later in the episode.
In the season three premiere, "Kill Ari (Part I)", the foofs had the freeze-frame shot added as well. 
NCIS (TV series)NCIS is an American police procedural drama 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 two episodes of the CBS series "JAG" (season eight episodes "Ice Queen" and "Meltdown").
The show, a spin-off from "JAG", premiered on September 23, 2003, on CBS.
To date it has aired for ten full seasons and has gone into broadcast syndication on USA Network.
Donald P. Bellisario is co-creator, along with Don McGill, as well as executive producer.
"NCIS" was originally referred to as Navy NCIS during season one; "Navy" was later dropped from the title.
In season seven, "NCIS" led to a spin-off series, "", starring Chris O'Donnell and LL Cool J.
In 2011, "NCIS" was voted America’s favorite television show.
The series finished its tenth season as the most-watched television series in the U.S. during the 2012–13 TV season.
On March 13, 2014, CBS renewed the series for a twelfth season.

"NCIS" spin-off.
In January 2003, CBS announced that Donald P. Bellisario was developing a "JAG" spin-off, revolving around the work of the Naval Criminal Investigative Service.
It was aired in April 2003 in a two-part backdoor pilot in which Commander Harmon Rabb is arrested, but later vindicated as innocent, for the murder of Lieutenant Loren Singer.
The two episodes, titled "Ice Queen" and "Meltdown", focused on the NCIS team, with most of the JAG regulars as supporting characters.
Whereas the episodes of "JAG" are primarily oriented on a mixture of courtroom drama and military activities in the field, "NCIS" is more focused, as the meaing of the acronym suggets, on criminal investigations.
"NCIS" also follows a different storytelling format from "JAG", emphasizing character humor to a larger extent than its parent program.
"NCIS" later produced its own spin-off, "", which shows a further departure from the styles and themes of "JAG".
The two episodes "Ice Queen" and "Meltdown" were edited down to a one-hour pilot film, which was then used to sell the idea of "NCIS" as a new series to CBS; the pilot used the title, "NCIS – The Beginning".
It was later also used to introduce the show to CBS affiliates and advertisers.
It was only broadcast once and is not available on home video.
Excluding the backdoor pilot, only two major characters from "JAG" have appeared in the "NCIS" series.
Patrick Labyorteaux appeared briefly as Lieutenant Bud Roberts in the "NCIS" first season episode "Hung Out to Dry", advising the NCIS team on a legal issue.
John M. Jackson returned in May 2013 as retired Rear Admiral A.J.
Chegwidden, now a civilian attorney in the private sector hired by Director Vance to provide legal representation for Special Agent Gibbs, in the season ten "NCIS" finale, "Damned If You Do".
While several other actors who played major roles on "JAG" have also appeared on "NCIS"; such as Scott Lawrence (Sturgis Turner on "JAG"), Steven Culp (Clayton Webb on "JAG"), and Michael Bellisario (Mikey Roberts on "JAG"); they played completely different characters when appearing on "NCIS".
First introduced in the NCIS back door pilot, Alicia Coppola appeared as Navy judge advocate Lieutenant Commander Faith Coleman in several episodes of NCIS.
Adam Baldwin played the same guest role, Navy Seal Commander Michael Rainer, in one episode of each show. 
NCIS: The Official TV Soundtrack is a series of soundtrack albums featuring music used in the CBS television series NCIS.
The first volume in the series, released on February 10, 2009, received attention for its method of compiling music for the album; show producers and writers were presented previously unreleased tracks from popular artists ""ranging from Perry Farrell to Jakob Dylan as the shows were being crafted, and then taking inspiration from those tunes to help craft the show.""
This method contrasted with the norm for TV soundtracks, which tend to be compilations of previously released music that is already available individually or on other albums.
