when did the new season of ncis start
NCIS (TV series) NCIS was originally referred to as Navy NCIS during season one; "Navy" was later dropped from the title as it was redundant (the "N" in "NCIS" stands for "Naval"). In season six, a two-part episode led to a spin-off series, NCIS: Los Angeles. A two-part episode during the eleventh season led to a second spin-off series, NCIS: New Orleans. While initially slow in the ratings, barely cracking the Top 30 in the first four seasons, by its sixth season, it became a top five hit, and has remained there since. In 2011, NCIS was voted America's favorite television show in an online Harris Poll.[3] The series finished its tenth season as the most-watched television series in the U.S. during the 2012â€“13 TV season.[4] On February 29, 2016, NCIS was renewed for its fourteenth and fifteenth seasons.[5][6] The fifteenth season premiered on Tuesday September 26, 2017.[7] Maria Bello will join the cast as a series regular from episode four,[8] replacing outgoing series regular Jennifer Esposito.[9]
