Fast National ratings for Tuesday, November 18, 2014.

"NCIS" and "NCIS: Los Angeles" were both up week-to-week, leading CBS to a dominant overall win and a tight victory among young viewers on Tuesday. 

Tuesday primetime featured a lot of little week-to-week fluctuations, including "New Girl" and "The Mindy Project" both rising a tiny bit despite a drop for "MasterChef Junior."

Over on ABC, a "Shark Tank" repeat comfortably outperformed recent comedy block numbers and helped "Marvel's Agents of S.H.I.E.L.D." inch up. Presumably that "Shark Tank" repeat also was responsible for some of the "MasterChef" decline, though that's total speculation.

Most of the night's increases and decreases were pretty minimal, but "NCIS: New Orleans" added nearly two million viewers over last week's airing, which came against the second half of a two-hour "The Voice," rather than NBC's significantly lower-rated comedies. And even those NBC comedies were way up from their last airing, though that airing was after a "Voice" clip show.

And both of The CW's dramas ticked up week-to-week. It was the most watched "Supernatural" since January.
