Another key night of the NBC watch continues apace.

Putting a lot of marketing muscle around its Monday night, the second regular airing of NBC's "The Voice" -- a two-hour episode -- grabbed a still-powerful 5.9 rating/15 share among 18-49 viewers -- down 12% from a week ago, which had a 6.7 rating, on the Monday after the Super Bowl.

Perhaps a little more worrisome is "Smash," which dipped almost 30%. Still, it scored a 2.8/7, winning an increasingly difficult 10 p.m. time period against CBS' "Hawaii Five-0"(2.6/7) and ABC's "Castle" (2.0/5).

The news is good for NBC overall. It won another Monday night, topping perennial Monday night champ, CBS -- with a 4.9/12 average for the Peacock Network and a 3.3/8 for the Tiffany Network.

Perhaps the better news for NBC was that two hours of "The Voice" (and "Smash") put the kibosh on all CBS shows, which hit season lows: "How I Met Your Mother" (3.4/10); "2 Broke Girls" (3.7/10); "Two and a Half Men" (3.8/9); "Mike & Molly" (3.3/8); and "Hawaii Five-0" (2.6/7).

Other contenders for the night were ABC (2.3/6), Fox (2.1/5), Univision (1.4/4), and the CW (0.6/1).

Two hours' worth of ABC's "The Bachelor" dropped a bit from the week before, to a 2.5/5. Fox's "House" saw a season-low 2.4/6; and "Alcatraz" went south as well, to a 1.9/4.

The CW's "Gossip Girl" hit a series-low 0.5/1 among 18-49 viewers, with 1.2 million overall viewers. "Hart Of Dixie" landed with a 0.6/1 -- the same as a week ago, with 1.6 million viewers.
