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.
