Day nine of the Summer Olympics in Beijing, featuring swimmer Michael Phelps' historic gold-medal triumph, gave NBC its most watched Saturday prime-time broadcast in 18 years, the network said Sunday.
The telecast averaged 31.1 million U.S. viewers, NBC's biggest audience for a Saturday night program since an episode of "The Golden Girls" spinoff "Empty Nest" drew 31.4 million viewers in February 1990, according to Nielsen Media Research data cited by the network.
