Usain Bolt and Simone Biles Deliver Above-Average Ratings for NBC

Network fell from last Sunday, despite historic performances

NBC's Sunday night Olympics coverage focused on Usain Bolt, and the iconic Jamaican sprinter delivered. Bolt achieved a historic feat by edging American Justin Gatlin for his third consecutive Olympic gold medal in the 100-meter competition. He won the race in 9.81 seconds, a number apparently not up to his standards, with Bolt later remarking to the press: "I expected to go faster, but I'm happy that I won. I did what I had to."

Simone Biles scored another gold medal last night, winning the vault competition and in the process becoming the first U.S. gymnast to win three gold medals in one Summer Olympics.

NBC Olympics ratings results from Sunday night were mixed, per Nielsen data. The NBC-only average total prime-time viewership was 26.7 million, down 15 percent from the same Sunday at London 2012 (31.3 million). The Total Audience Delivery (TAD) average from last night is 28.1 million, still down 10 percent from the same Sunday at London 2012.
