NBC continued its winning streak even after the dust from the Olympics has settled, dominating the night of August 24 with an average 1.5 rating in the adults 18-49 demographic and 7.8 million viewers overall. That was driven by a repeat of “America’s Got Talent” at 8 p.m. (1.4 rating, 7.2 million viewers), a new episode of “AGT” at 9 p.m. (2.1 rating, 10.5 million viewers) and a fresh installment of “The Night Shift” (1.1 rating, 5.6 million viewers). That 2.1 score makes Wednesday’s new episode of “AGT” the highest-rated results show for the competition series, excluding finales, since July 30, 2014.

CBS’ “Big Brother” also climbed on Wednesday night, notching a strong 2.0 rating and 6.4 million viewers at 8 p.m. opposite the “AGT” repeat. And Fox’s “Masterchef” was up a tenth over its last episode in the 8-10 p.m. slot, just trailing the first hour of “AGT” in the demo with a 1.3 rating and 4.1 million viewers. The CW’s new episode of “Penn & Teller: Fool Us” scored a 0.4 rating and 1.5 million watchers at 8 p.m., followed by a new episode of “Whose Line Is It Anyway” at 9 p.m., which maintained its lead-in’s 0.4 in the demo and earned 1.3 million viewers.

ABC was in repeats for the night, and CBS aired a repeat of “Criminal Minds” in the 9 p.m. hour, followed by a new “American Gothic,” which nabbed a 0.5 in adults 18-49 and 2.6 million viewers.

For the night, Fox muscled past CBS with an average rating of 1.3 in adults 18-49 and 4.11 million viewers overall, followed by CBS’ 1.1 rating and 4.09 million watchers. ABC’s reruns produced a 0.8 demo rating and 2.8 million viewers, followed by The CW’s 0.4 rating and 1.4 million viewers.
