NBC's coverage of the Summer Olympics may be down, but the ratings are still huge.
NBC: RIO 2016 Summer Olympics (26.5 million/7.8 rating) reigned supreme.
CBS: Big Brother (5.7 million/1.8 rating) held up well against the Olympics, but BrainDead (1.8 million/0.3 rating) remained pretty dead out of an encore of Madam Secretary (2.4 million/0.3 rating).
ABC: Celebrity Family Feud (5.5 million/1.1 rating), The $100,000 Pyramid (4.5 million/0.9 rating) and Match Game (3.6 million/0.8 rating) returned to originals, but they all took a hit.
Fox: Encores of The Simpsons (1.4 million0.5 rating), Brooklyn Nine-Nine (1 million/0.4 rating), Family Guy (1.3 million/0.6 rating) and Last Man on Earth (1 million/0.4 rating) filled the night.
