In the weekly TV section, what do the letters "N" and "S" in parentheses mean after program listings? And why doesn't the section indicate programs that are repeats?
One of the letter notations you asked about does indicate when a program is a repeat, or, more accurately, when it's not. According to Tribune Media Services, which provides the listings that appear in the Saturday TV Week section, (N) and (S) are part of new standards for program listings.
The letter (N) indicates a first-run, or new, program. So listings not followed by (N) indicate the program is a repeat. The (S) notation indicates the program includes sexual content. And (CC), of course, indicates the program is closed captioned.
