NBC has held the American broadcasting rights to the Summer Olympic Games since the 1988 games and the rights to the Winter Olympic Games since the 2002 games. In 2011, NBC agreed to a $4.38 billion contract with the International Olympic Committee to broadcast the Olympics through the 2020 games, the most expensive television rights deal in Olympic history. NBC then agreed to a $7.75 billion contract extension on May 7, 2014, to air the Olympics through the 2032 games. NBC also acquired the American television rights to the Youth Olympic Games, beginning in 2014, and the Paralympic Games for the 2014, 2016, 2018, and 2020 editions. NBC announced more than 1200 hours of coverage for the 2020 games, called “unprecedented” by the International Paralympic Committee. NBC is one of the major sources of revenue for the IOC.
