Ratings: NCIS Hits Season High, LA Catches New Girl, Sex-y Glee Inches Up in Demo

That NCIS is one feisty nine-year-old.

TV’s most-watched drama series this week hit a season high by cracking the 20 million viewer ceiling for the first time this fall, and again topped Tuesday with the 18-49 demo. All told, it drew 20.3 mil while scoring a 4.1, up a few percentage points week-to-week.

Offshoot NCIS: Los Angeles (15.6 mil/3.4) had a good night as well, matching Fox’s New Girl for the first time this season in the demo (with its first half hour). The good news for Fox is that if New Girl‘s rating is adjusted up in the Nielsen finals, as it was last week, it will have held steady after returning from its X Factor/baseball hiatus with a decrease.

Now, let’s talk about Glee sex, baby! The buzzy episode of the musical dramedy, with 6.9 million viewers and a 3.1 rating, inched up a tenth in the demo, but dipped 8 percent in total audience week-to-week.
