BERLIN, March 13 (Reuters) - The International Olympic Committee and Comcast ( CMCSA )-owned NBCUniversal have agreed on a $3 billion extension of their Olympic Games media rights deal for the United States to 2036, the IOC said on Thursday.

"The extension of the media rights for the 2033-2036 cycle, covering the Olympic Winter Games Salt Lake City-Utah 2034 and the Olympic Games 2036 (host yet to be determined), is valued at $3 billion and is a major contribution to the long-term financial stability of the entire Olympic Movement," the IOC said in a statement.

The U.S. broadcaster has traditionally been the biggest single biggest source of revenue for the IOC.
