An all-time low, another even lower number and a sizable drop from last week marked ABC’s Tuesday night ratings, based on Nielsen overnights for the key 18-49 demo, as the Alphabet Network finished below even the CW — placing sixth among the broadcast networks.

TVbytheNumbers.com reports that ABC failed to crack a 1.0 in the key demo, averaging a 0.9 rating in adults 18-49 for prime time, below CW’s 1.1. NBC won the night with a 1.9.

ABC’s "Trophy Wife" fell to an all-time low, losing one-tenth of a point from a week ago to a 1.0 in the 18-49 demo. "Killer Women" remained in bottom-feeder territory at 10 p.m., matching last week’s 0.7. "The Goldbergs," the network’s best-performing program of the night, fell 17% to a 1.5.

ABC opened prime time with a repeat of "Marvel’s Agents of S.H.I.E.L.D.," which came in right at the network’s average for the night with a 0.9.

The CW, which generally remains mired in sixth place among the broadcast nets, lifted itself up on the strength of "Supernatural" (1.1 average in 18-49, up 10% from last week) and "The Originals" (1.0, up 11%).

NBC got what it needed for the win from its two-hour "The Biggest Loser," which bounced back from last week’s season low, rising 12% to a 1.9 average in viewers 18-49, while "Chicago Fire" matched last week’s season low, a 1.8. But while NBC took a win in the demo, CBS came out on top in total viewers with an all-repeat drama lineup.

CBS had a 1.8 average in 18-49 for an "NCIS" repeat (with 13.9 million total viewers), a 1.6 for a rerun of "NCIS: Los Angeles" (10.4 million total viewers) and a 1.2 for a "Person of Interest" repeat (7.3 million total viewers).

Fox came in second in the 18-49 demo, as its comedy lineup came back strong from last week’s lows. Leading the way was "Brooklyn Nine-Nine," up 36% from last week’s season low with a 1.9, while "Dads" improved 25% from a series low to a 1.5.

Fox’s "New Girl" rose 13% from its season low to a 1.8 in adults 18-49, and "The Mindy Project" rebounded 36% from its season low to a 1.5.

For prime time overall, NBC led the way in the 18-49 demo with a 1.9 average, followed by Fox (1.6 average), CBS (1.5), Univision (1.3), CW (1.1) and ABC (0.9). CBS finished well ahead in total viewers with 10.5 million, topping NBC (6.8 million), Fox (3.798 million), ABC (3.791 million), Univision (3.2 million) and CW (2.5 million).
