what does 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 two seasons, the third season showed progress, consistently ranking in the top 20, and by its sixth season, it became a top five hit, having 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 joined the cast as a series regular from episode four,[8] replacing outgoing series regular Jennifer Esposito.[9]
