NBC's broadcast of Saturday's 140th running of the Kentucky Derby -- which saw the 3-year-old chestnut California Chrome capture the crown -- drew 15.3 million television viewers.
The TV audience was down nearly 6% compared with last year, when an estimated 16.2 million people watched Orb win at Churchill Downs, according to numbers from ratings giant Nielsen.
Nonetheless, NBC celebrated its strong showing, noting that the weekend race marked the fourth time in six years that NBC's coverage of the Kentucky Derby had topped 15 million viewers.
The Comcast-owned TV network also said it set a record for the number of minutes of coverage streamed on its digital platforms: 4.4 million.
The numbers represented NBC's best showing on a Saturday since the Winter Olympics in February.
More than 164,900 people crowded into Churchill Downs in person, including 21st Century Fox Chief Executive Rupert Murdoch, who attended as the guest of Sen. Rand Paul (R-Ky.).
