Question: What was NCIS named prior to being named NCIS?
About the article "NCIS (TV series)", section "Name".

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.
