TV ratings: ‘Voice,’ ‘Person of Interest’ down; ‘Trophy Wife’ up

NBC has won its sixth straight Tuesday night in the key young adults demographic, though “The Voice” is singing in a lower register this week.

With two hours of “knockout rounds” -- which typically fare worse in the ratings than the preceding “battles” -- “The Voice” fell 15% in the advertiser-desired 18-49 demo to a 3.5, still making it the highest-rated telecast of the night, according to early numbers from Nielsen. “The Biggest Loser,” the weight loss show now in its 15th cycle, drew a rating of 1.8, down 10% from last week.

NBC, which averaged 9.6 million viewers overall, garnered a 3.0 rating in 18-49, in which a ratings point equals roughly 1.3 million people, giving it another Tuesday win in the demo.

ON LOCATION: Where the cameras roll

Propelled by “NCIS,” with nearly 19 million viewers, CBS has the biggest overall audience, with some 15.2 million tuning in on average. The “NCIS” demo rating was flat with last week at a 3.0, while “NCIS: Los Angeles” grew its number by 4% to a 2.6. “Person of Interest,” CBS’ 10 p.m. series, fell 18% to a 1.8.

ABC kicked off its prime time lineup with a rerun of “Marvel’s Agents of S.H.I.E.L.D.,” but the lack of the usually big lead-in didn’t seem to hurt the network’s freshman comedies. “The Goldbergs” matched last week’s 1.7 rating, followed by “Trophy Wife,” which rose 17% to a 1.4.

After a three-week absence, Fox’s “The X Factor” returned for a special airing to 4.72 million viewers and a 1.5, down 25% from its last telecast, which was on a Thursday and didn’t have to compete with “The Voice” in its second hour.

On the CW, “Supernatural” and “The Originals” both held steady with last week, earning ratings of 1.1 and 0.9, respectively.
