After a couple of atypical Monday nights, it was status quo as all networks returned with originals last night and NBC’s combo of “The Voice” and “Revolution” won each half-hour in key demos.

Two weeks ago, it was the final presidential debate preempting two-thirds of the night’s programs and last week saw CBS air repeats on a night of big news surrounding Hurricane Sandy while Fox went with an “X Factor” repeat due to the quick end to the World Series.

Last night, according to preliminary national estimates from Nielsen, “The Voice” (4.5 rating/11 share in adults 18-49, 12.2 million viewers overall) was easily the night’s top-rated entertainment series in both 18-49 and 25-54 (5.2/11), and 10 p.m. rookie “Revolution” (2.9/8 in 18-49, 7.7 million viewers overall) stood as the No. 1 drama in demos.

Both shows were off slightly from last week, with “Revolution” hitting a season low — though it’s still comfortably the top-rated 10 p.m. drama in 18-49 on any night and on any network.

CBS was runner-up among the broadcasters Monday, but its “How I Met Your Mother” was at a season low (2.8/7 in 18-49, 7.2 million viewers overall). “Partners” (2.1/5 in 18-49, 5.8 million viewers overall) matched the delivery of its most recent episode, while 9 o’clock half-hours “2 Broke Girls” (3.3/8 in 18-49, 9.1 million viewers overall) and “Mike & Molly” (2.8/7 in 18-49, 8.8 million viewers overall) were off a bit. At 10, “Hawaii Five-0” (2.0/5 in 18-49, 7.3 million viewers overall) was in line with its prior same-night average.

ABC’s “Dancing With the Stars” (2.1/5 in 18-49, 13.4 million viewers overall) and “Castle” (1.9/5 in 18-49, 10.1 million viewers overall) matched their season lows, and Fox’s “Bones” (2.0/5 in 18-49, 7.3 million viewers overall) and “Mob Doctor” (1.0/2 in 18-49, 3.4 million viewers overall) were in line with their most recent airings. “Dancing” remained the night’s most-watched entertainment series as ABC led the night by that measure.

The night continues to be a struggle for CW, with vet dramas “90210” (0.4/1 in 18-49, 0.9 million viewers overall) and “Gossip Girl” (0.3/1 in 18-49, 0.7 million viewers overall).

Univision was above average thanks to the two-hour finale of “Abismo de Pasion” (2.0/5 in 18-49, 4.9 million viewers overall).

ESPN was expected to be in the running for the night’s demo lead with its “Monday Night Football” matchup between the Philadelphia Eagles and New Orleans Saints.

Preliminary 18-49 averages for the night: NBC, 4.0/10; CBS, 2.5/6; ABC, 2.0/5; Univision, 1.7/4; Fox, 1.5/4; CW, 0.4/1.

In total viewers: ABC, 12.3 million; NBC, 10.7 million; CBS, 7.6 million; Fox, 5.4 million; Univision, 4.3 million; CW, 0.8 million.
