CBS rode its steadfast Tuesday night drama lineup to a prime-time ratings win as shows on all three of the other big four networks notched season lows or series lows, based on Nielsen overnights for the key 18-49 demo.

In total viewers, CBS pulled in almost twice the number of its closest competitor. TVbytheNumbers.com reports that CBS averaged 14.498 million viewers for prime time, with second-place NBC settling for 7.635 million.

NBC, ABC and Fox all had shows that struggled in the 18-49 demo. Even while ranking as the top broadcast show of the night, NBC's "The Voice" registered a season-low 3.0 average rating, falling 12% from a week ago. ABC's "Marvel's Agents of S.H.I.E.L.D." matched its all-time low with a 1.8, off 14% from last week, while Fox's "Glee" turned in a 0.9, equaling its series low and falling 18% from a week earlier.

CBS was mostly down vs. a week ago. "NCIS" delivered a 2.3 average in 18-49, down 8% from last week; "NCIS: Los Angeles" equaled last week's 2.4; and "Person of Interest" fell 5% to a 1.9.

Leading out from "The Voice," NBC's "About a Boy" ticked up 5% from last week to a 2.1 average in viewers 18-49, and "Growing Up Fisher" held steady with a 1.7. A repeat of "Chicago Fire" at 10 p.m. managed a 1.0.

ABC's "The Goldbergs" lost 12% from its previous original with a 1.5 in the 18-49 demo. "Trophy Wife" held steady with a 1.0 and a repeat of "Resurrection" at 10 p.m. settled for a 0.7.

Fox led out from "Glee" with back-to-back episodes of "The Mindy Project," with both installments delivering 1.0 ratings in adults 18-49 — off 33% from the show's most recent original back in January.

For prime time overall, CBS led the way in the 18-49 demo with a 2.2 average, followed by NBC (2.0 average), ABC (1.3), Univision (1.1) and Fox (0.9). CBS was well ahead in total viewers with 14.5 million, leading NBC (7.6 million), ABC (3.9 million), Univision (2.7 million) and Fox (2.3 million).
