TV ratings: ‘Celebrity Wife Swap’ season opens low; ‘SHIELD’ up

ABC’s “Celebrity Wife Swap” probably wishes it could trade in the ratings for its third season premiere.

According to early numbers from Nielsen, the Tuesday 10 p.m. reality show earned a rating of 1.0 among key 18- to- 49-year-olds and 3.1 million viewers overall for the episode that featured a spouse-switch between Daniel Baldwin and Jermaine Jackson.

In the advertiser-coveted demographic, it was down by more than half from last year’s season opener (which aired at 8 p.m.) for the lowest “Wife Swap” or “Celebrity Wife Swap” premiere rating ever.

The better news for ABC came from “Marvel’s Agents of S.H.I.E.L.D.” airing at 9 p.m. this time instead of its usual 8 p.m. time-slot and gaining a tenth of a point from last week for a 2.0 in 18-49. That matches its rating from two weeks ago and the comic book series also tends to rise slightly in the final figures.

NBC’s new “Voice”-backed comedies fared well. “About a Boy” rose 12% week-to-week to a 1.9 in 18-49 and “Growing Up Fisher” increased its rating 7% to a 1.6. “Chicago Fire” slipped slightly to a 1.7.

“The Voice” itself was again the highest-rated show in the key demo with a 2.9, the same as last week. For the night, NBC had a slight edge over CBS in 18-49 (2.1 vs. 2.0), though CBS had more viewers overall (14 million vs. 8.4 million).

CBS’ “NCIS,” Tuesday’s most-watched program, fell 19% week-to-week to a 2.1, the same rating brought in by its 9 p.m. offshoot “NCIS: Los Angeles.” “Person of Interest” fell 11% to a 1.7.

Fox’s Tuesday lineup continued to struggle as “Glee” remained at a 1.0, “New Girl” returned after a two-week break for a 1.1 and “Mindy Project” fell 9% week-to-week to a 1.0.
