The winning streak is over for NBC, which had the Rio Olympics as the centerpiece of a ratings run that saw the network notch 21 consecutive nights as the most watched network.

“It was the longest string of consecutive victories among television viewers since the Nielsen company began keeping more precise records in 1987,” the AP reports. “The dominance of the Summer Olympics in Rio de Janeiro was the chief reason why, but NBC kept it going until last Friday when CBS won with an NFL exhibition game between Cleveland and Tampa Bay.”

On a weekly basis, NBC has won total viewers for the past nine consecutive weeks, its longest streak since 1997, the story reports, citing Nielsen data.

“Behind the success of ‘America’s Got Talent’ and ‘American Ninja Warrior,’ NBC has increasingly done well during the summer months on broadcast television, and the Olympics emphasize that trend,” the AP reports. “It’s not nearly as important as winning the traditional television season from September to May, however, which CBS has dominated for several years.”
