I hope the IOC revokes NBC's contract but doubt it cause of all the money being fed back to the IOC.
Outrage against NBC started in 1996 for me when they announced "And that concludes our broadcast from Olympic stadium" right as the men's 10,000 meters (last event in the stadium that night) was getting underway. It blocked Americans from viewing that event and refused to even acknowledge its existence even while the race was unfolding in front of the announcers! I had to get the newspaper the next day to get the results!
NBC then created a video with soundtrack for the women's 10,000 meters featuring Catherine Ndereba who finished 5th or 6th. Meanwhile, the dramatic historic battle between Wang Junxia (China) and Fernanda Ribeiro (Portugal) was ignored.
Then there was there "plausibly live" fraud against the American people.
This is just a sample of the historical crimes of NBC against the Olympic spirit. They can choke on their money but what they are doing will slowly kill off the Olympics as a true sporting event.
