NBC has won another Tuesday in key demos behind “The Voice” and nice sampling numbers for new comedy “Crowded,” while CBS prevailed as usual in total viewers, with the 300th episode of “NCIS” leading the way. ABC’s Tuesday troubles continued, and its new biblical-themed drama “Of Kings and Prophets” has entered pull-me-now territory after a week-two drop from its already low-rated debut of last week.

The start of Daylight Saving Time had a typical effect on early-evening viewing levels, meanwhile, with the percentage of adults 18-49 watching during Tuesday’s opening half-hour (26.2) down a meaningful 7% from the previous week (28.3). That leveled off later in primetime, with the 10 p.m. half-hour (30.4) steady week to week and the 10:30 p.m. half-hour (28.6) actually up a little from last week. Interest in primary voting results on cable news networks may have helped inflate tune-in later in the evening.

According to preliminary “live plus same-day” national estimates from Nielsen, NBC’s two-hour “The Voice” (2.7/9 in 18-49, 11.1 million viewers overall) easily led its two-hour block in 18-49, down 0.4 from last week when the CBS dramas were in repeats. It peaked in 18-49 at 9:30 p.m., when its 2.9 rating nearly equaled the combined three-network total of CBS, ABC and Fox (3.1).

At 10 p.m., a special preview of “Crowded” averaged a 1.8/6 in 18-49 and 6.8 million viewers overall, and a second original at 10:30 did a 1.4/5 and 5.3 million — both winning their timeslots in 18-49. It’s always hard to gleen too much out of special previews, but this one performed somewhere between “Telenovela” (1.4/0.9 for its previews) and “Superstore” (2.0/1.6). The show, starring Patrick Warburton and Carrie Preston as parents who reluctantly welcome their young-adult children back home, moves into its regular Sunday 9:30 p.m. timeslot this week, airing behind “The Carmichael Show.”

At CBS, “NCIS” was on the low side of its season range (2.0/7 in 18-49, 14.8 million viewers overall) in its first airing during Daylight Saving Time but it was able to match its prior original of two weeks ago in 18-49. The 300th episode of the Mark Harmon-fronted series stood as Tuesday’s No. 1 scripted program in key demos and No. 1 overall in total viewers. “NCIS: New Orleans” (1.6/5 in 18-49, 11.8 million viewers overall) and “Limitless” (1.1/4 in 18-49, 5.9 million viewers overall) also matched their most recent originals in 18-49, with each placing second to NBC for their respective hours in 18-49 as well as 25-54.

The combo of Daylight Saving Time and an original “NCIS” seemed to affect it ABC’s “Fresh Off the Boat” (1.1/4 in 18-49, 4.2 million viewers overall), which came down a significant 0.3 from last week. “The Real O’Neals” (1.0/4 in 18-49, 3.6 million viewers overall) limited its decline to a single tenth, and it at least out-performed the recent average of “The Muppets” in the time period. “Marvel’s Agents of SHIELD” (1.0/3 in 18-49, 2.9 million viewers overall) was also down a tenth to establish a series low, and “Of Kings and Prophets” cratered in its second week at 10 (0.5/2 in 18-49, 2.4 million viewers overall), down 0.3 from its premiere. Last fall, “Wicked City” opened to a 0.9 in the hour, fell to a 0.7 in week two and was then canceled after hitting a 0.4 in its third week.

Like “Fresh Off the Boat,” Fox’s “New Girl” hit a low leading off the night (1.0/4 in 18-49, 2.3 million viewers overall), down 0.2 from last week. It was followed by a repeat “Grandfathered” (0.5/2 in 18-49, 1.5 million viewers overall) and originals of “Brooklyn Nine-Nine” (0.8/3 in 18-49, 2.0 million viewers overall) and “The Grinder” (0.6/2 in 18-49, 1.6 million viewers overall), which both matched their most recent first-runs.

CW was in repeat mode one more week with “The Flash” (0.4/1 in 18-49, 1.15 million viewers overall) and “iZombie” (0.2/1 in 18-49, 0.7 million viewers overall).
