Following a wholesale lineup change in its last-place daytime sked, NBC saw its ratings fortunes sink during the week of June 14.

With “John & Leeza From Hollywood” and “Caesars Challenge” rolling out of the gate, the Peacock web’s daytime household average dropped to a 2.7 rating/10 share from a 3.0/11 the previous week, according to Nielsen’s daytime and fringe ratings report.

“John & Leeza” scored a 14th-ranked rating of a 2.1/8, tying with ABC’s second portion of the “Home” show.

Despite its low overall ranking, the new talkshow performed better than the morning slot’s previous occupants, “Scrabble” and “Scattergories.”

“John & Leeza” was up 24% in households, 33% among women 18-49 (1.2) and 22% among women 25-54 (1.1). It also climbed 2 share points over the second-quarter to-date average of the two gameshows it replaced.

“Caesars Challenge,” meanwhile, placed 18th out of 19 shows with a 1.5/6. That is a mere tenth of a point out of the cellar (a dubious honor that went to CBS’ “Family Feud”) and a tenth of a rating point behind the final airing of “Family Secrets,” which occupied the slot the previous week.

If there is a bright side, the program is up 15% in households and 1 share point over the second quarter-to-date average of “Secrets.”

The new shows failed to have any impact on the front runners.

CBS, led by “The Young and the Restless” (8.5/31), easily swept to its 224th consecutive weekly household victory in daytime. It climbed a tenth from the previous week to a 5.5/21, while ABC dropped a notch to a 4.8/17.

In the key women 18-49 demo, however, the alphabet web won with a 3.8/26. CBS trailed with a 3.1/22 while NBC collected a paltry 1.6/12.

Elsewhere, ABC’s “Good Morning America” extended its winning streak to 32 consecutive weeks with a 4.0/19, giving it an 11% advantage over NBC’s “Today” show (3.6/18) and a 60% lead over “CBS This Morning” (2.5/12).

The early morning race is closer in the key adult 18-49 demo, with “GMA” posting a 1.6/21 and “Today” grabbing a 1.5/19. CBS’s morning show trails with a 0.8/11.

With 12 weeks gone in Nielsen’s second quarter, “GMA” is in front of “Today” by a comfortable 2-share margin and 7 shares ahead of “CBS This Morning.”

“The Tonight Show With Jay Leno” finally broke “Nightline’s” late night ratings grip during the week.

“Tonight” posted a 5.1/14, compared to a 4.9/13 for “Nightline” and a 3.0/8 for CBS’ “Crime Time” action hours.

NBC’s average is for three days, with Wednesday and Friday excluded because of a runover in NBC playoff coverage. Only three days are included in ABC’s average because of “U.S. Open” golf highlights.

The Fox Children’s Network continued its winning ways on Saturday mornings, finishing with a 4.6/22 among kids 2-11 and a 2.8/12 household rating.

CBS came in second with kids, averaging a 3.8/19, but the web’s 2.3/10 household mark put it in third place behind NBC (2.7/12).

Catering to a teen audience, NBC’s “Saved by the Bell-2” and “Saved by the Bell-1” ranked No. 2 and 3 among all Saturday morning shows in teens.

ABC finished with a 3.5/17 among kids and a last-place 2.2/10 in the household rankings.
