NBC’s “Revolution,” taking advantage of its potent lead-in from “The Voice,” opened impressively with its early premiere Monday, but the night saw a very sluggish start for Fox’s “Mob Doctor.” Both shows bowed a week before the start of the television season, with ABC and CBS joining the party next week.

According to preliminary national estimates from Nielsen, “Revolution” averaged a big 4.1 rating/11 share in adults 18-49 and 11.7 million viewers overall in the 10 o’clock hour, easily topping a a country music special on ABC (1.6/4 in 18-49, 6.0 million viewers overall for its final hour) and a repeat of CBS drama “Hawaii Five-0” on CBS (0.9/2 in 18-49, 4.4 million viewers overall). In a promising sign, the show held up pretty well in its second half-hour (4.4/11 at 10 and a 3.8/10 at 10:30).

Excluding special previews, “Revolution” had the strongest start in 18-49 for any NBC drama in five years (since “Bionic Woman” in September 2007) and the best for any drama on any network in nearly three years (since ABC’s “V” in October 2009). No regular 10 p.m. drama has delivered a higher 18-49 rating since ABC’s “Private Practice” in January 2010.

The two-hour installment of “The Voice” (4.6/12 in 18-49, 13.4 million viewers overall) grew by about 10% over last week, peaking with a 5.0/12 at 9:30 leading into “Revolution.”

Last season, NBC struggled to launch any of its dramas in the fall, with Monday’s “Playboy Club” drawing a weak 1.6/4 in 18-49 for its premiere on the opening night of last season (airing behind “The Sing Off”). The net’s best result for a new drama came at midseason, when “Smash” followed “The Voice” on Monday with a 3.8/10 in 18-49 while drawing 11.4 million viewers overall.

Among adults 18-49, Fox’s “Mob Doctor” (1.5/4 in 18-49, 5.1 million viewers overall) ran fifth among the broadcasters in the 9 o’clock hour, coming in with about half of the young-adult audience of last year’s Monday drama premiere of “Terra Nova” (3.1/8 in 18-49, 9.2 million viewers overall), which launched in the second week of the season and aired a two-hour episode.

Kicking off the night for Fox was the season premiere of “Bones” (2.3/6 in 18-49, 7.8 million viewers overall), which was down from its premiere of last season (3.3/8 in 18-49, 10 million viewers overall), when it started in early November and aired behind “The X Factor” on Thursday.

Elsewhere on Monday, ABC’s three-hour “CMA Music Festival: Country’s Night to Rock” (1.7/4 in 18-49, 6.2 million viewers overall) was on par with last year’s telecast. Its numbers could come down, though, due to a NFL preemption on its Atlanta station for the Falcons game on “Monday Night Football.”

CBS aired an hour of repeats of both “How I Met Your Mother” (1.4/4 in 18-49, 4.3 million viewers overall) and “2 Broke Girls” (1.6/4 in 18-49, 4.9 million viewers overall).

Univision was led by “Abismo de Pasion” (1.8/4 in 18-49, 4.2 million viewers overall) at 9. At CW, “The L.A. Complex” (0.4/1 in 18-49, 0.8 million viewers overall) was up slightly week to week.

Next Monday sees the return of ABC’s “Dancing With the Stars” and CBS’ comedy block, including new 8:30 p.m. show “Partners.” Also back with their premieres in the 10 o’clock hour are “Castle” and “Hawaii Five-0.”

Preliminary 18-49 averages for the night: NBC, 4.4/12; Fox, 1.9/5; ABC, 1.7/4; Univision, 1.6/4; CBS, 1.3/3; CW, 0.3/1.

In total viewers: NBC, 12.8 million; Fox, 6.5 million; ABC, 6.2 million; CBS, 4.5 million; Univision, 3.8 million; CW, 0.7 million.
