NBCUniversal has signed an unprecedented $US7.65 billion ($A8.28 billion) deal for the rights to broadcast the Olympic Games in the US until 2032.
The agreement covers all media platforms, including free-to-air television, subscription television, internet and mobile, from 2021.
NBCU, which in 2011 acquired the rights until 2020, has been broadcasting the games to American audiences since Tokyo 50 years ago.
International Olympic Committee president Thomas Bach says the deal ensures the long-term financial security of the Olympic movement, with 90 per cent of the organisation's revenue distributed to international sports federations, 204 national Olympic committees and their Olympic teams, as well as organising committees of each Games.
"The IOC has worked in close partnership with NBC for many decades, and we are thrilled we will continue to work with them through to 2032," Bach said in a statement.
