New NBC drama “Believe” received fairly good sampling behind “The Voice” on Monday, a night on which reality shows “The Voice” on NBC and “The Bachelor” (with its finale) on ABC ruled the ratings roost. The Alphabet and Peacock were in a virtual draw for the lead among young adults.

Overall, the onset of Daylight Saving Time had a noticeable effect in television usage, with the number of adults 18-49 watching during any average minute of primetime down 10% from the previous week.

According to Nielsen, “The Voice” averaged a 3.7 rating/11 share in adults 18-49 and 13.6 million viewers overall from 8 to 10 p.m., down 18% from last week for a season low but still impressive considering its was up against the “Bachelor” finale. After tying from 8 to 8:30 p.m., the NBC show finished ahead of the ABC show in adults 18-49 in each half-hour and ended up winning by a 3.7 to 3.2 count for the two hours.

At 10 p.m., the special preview of “Believe” averaged a 2.7/8 in 18-49 and 10.7 million viewers overall — matching the demo score of “The Blacklist” in the same hour a week earlier. This week, it shifts to its regular Sunday 9 p.m. timeslot, where its competition will include ABC’s “Resurrection,” which got off to a hot start a couple of nights ago. (In updated nationals, “Resurrection” did a 3.8 in 18-49, tying it with NBC’s “The Blacklist” as the season’s No. 2 drama premiere, behind only ABC’s “Marvel’s Agents of SHIELD”).

At ABC, the three-hour block of “The Bachelor,” which featured the finale as well as the “After the Final Rose” special, averaged a 3.4/10 in 18-49 and 10.1 million viewers overall — down about 15% in the demo from last year’s 4.0 for the night; a year ago, “Bachelor” had it a little easier opposite “The Biggest Loser” and “Deception” on NBC.

From 8 to 10 p.m., the “Bachelor” finale averaged a 3.2/9 in 18-49 and 11 million viewers overall, rising about 40% from its penultimate episode of the previous week. At 10, the “After the Rose” special easily led its hour with a 3.8/11 in the demo and 13.6 million total viewers.

CBS mixed in a couple of repeats alongside a pair of originals in its comedy block. Following one of the final new episodes of “How I Met Your Mother” (2.7/9 in 18-49, 7.7 million viewers overall), which was down about 15% from last week, was a repeat of “2 Broke Girls” (1.4/4 in 18-49, 10.7 million viewers overall). “Mike & Molly,” which started its season late and has more originals available for CBS, hit a low at 9 and was followed by an encore “Mom” (1.3/3 in 18-49, 5.8 million viewers overall) and a new “Intelligence” (1.3/3 in 18-49, 6.5 million viewers overall), which was up a tick from last week and may have benefited from the lack of “Castle” in the hour for ABC.

Fox premiered “Bones” on its new night (1.7/5 in 18-49, 6.5 million viewers overall), faring a little better than former timeslot occupant “Almost Human” despite the start of Daylight Saving Time. And at 9, the recently renewed “The Following” (1.5/4 in 18-49, 4.9 million viewers overall) was about on par with last week.

CW aired original episodes of its low-rated “Star-Crossed” (0.3/1 in 18-49, 1.0 million viewers overall) and “Beauty and the Beast” (0.2/1 in 18-49, 0.8 million viewers overall), with the latter’s finale doing nothing to help its renewal chances.

Preliminary 18-49 averages for the night: ABC, 3.4/10; NBC, 3.3/10; CBS and Fox, 1.6/5; CW, 0.2/1.

In total viewers: NBC, 12.6 million; ABC, 10.1 million; CBS, 6.6 million; Fox, 5.7 million; CW, 0.9 million.
