Name
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, to:


 * 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.)

Flair
From the season-two episode "Lt. Jane Doe" onwards, the series began showing two-second-long black-and-white clips. These clips 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. In the season-three premiere, "Kill Ari (Part I)", a freeze-frame shot was also used with the very end of most episodes turned into a freeze frame, as well.

Awards and Achievements
Throughout its run, "NCIS" has received many awards and nominations since it premiered on September 23, 2003 including the ALMA Awards, ASCAP Awards, BMI Film & TV Awards, Emmy Awards and the People's Choice Awards.
