NBC continued its stranglehold on the Monday night prime-time broadcast ratings last night, based on Nielsen overnights for the key 18-49 demo, with its two-hour "The Voice" complemented by another strong showing for its new drama series "The Blacklist."

TVbytheNumbers.com reports that the two shows topped everything else on broadcast, with "The Voice" delivering a 4.5 average rating in viewers 18-49 to easily finish as the No. 1 show of the night — even while slipping 2% from last week. The breakout hit "The Blacklist" was the No. 2 show, ticking up 3% to a 3.2.

The report cautions that a football pre-emption in Indianapolis could cause the numbers to be adjusted downward more than usual, but NBC finished with plenty of cushion over its closest rivals.

Second-place Fox was paced by its new drama "Sleepy Hollow," which dipped 7% from a week ago to a 2.6 average in 18-49, while "Bones" slipped 5% to a 2.0.

ABC saw its two-hour "Dancing with the Stars" improve slightly from last week, climbing 5% to a 2.1 average in the 18-49 demo. "Castle" also was up, surging 16% to a 2.2.

CBS came in fourth overall, paced by "How I Met Your Mother" with a 3.0 average in adults 18-49 — equaling last week’s number. "2 Broke Girls" made its time slot premiere at 8:30 and ticked up 9% from last week’s series low to record a 2.5. "Mom" slipped 10% to a 1.9, while the struggling "Hostages" equaled its series low from a week ago, a 1.2 average.

NBC averaged a 4.0 in the 18-49 demo for prime time, easily outdistancing Fox (2.3 average), ABC (2.1), CBS (2.0) and Univision (1.4). The race for total viewers was much tighter, but NBC again finished on top with 13.0 million, ahead of ABC (12.2 million), Fox (7.3 million), CBS (7.0 million) and Univision (3.6 million).
