ncis shell shock ratings TV ratings: 'NCIS' and 'The Voice' lead a quiet Tuesday while 'New Girl' hits series lowFast National ratings for Tuesday, Nov. 20, 2012

Ratings were down for the most part Tuesday as people started to ease into the Thanksgiving holiday. “NCIS” fell some in viewers (but was flat in adults 18-49), and “The Voice” was down as well. So were “New Girl,” which hit a series low in adults 18-49, and The CW’s “Hart of Dixie” and “Emily Owens, M.D.”

On the plus side, “Vegas” improved its 18-49 numbers from a week ago for CBS, and NBC’s “Go On” held steady. “Private Practice” also rebounded a little from its series low last week.

CBS led all three hours of primetime in viewers and averaged 13.9 million viewers and an 8.7 rating/14 share. ABC (7 million, 4.7/8) came in second, a little ahead of NBC’s 6.4 million and 4.0/6. FOX (3.25 million, 2.0/3) was fourth, and The CW (1.2 million, 0.8/1) trailed.

The Eye also led among adults 18-49 with a 2.5, edging NBC’s 2.3. FOX came in third with a 1.5. ABC came in fourth with a 1.4, and The CW scored a 0.5.
