The US broadcaster NBC is facing growing criticism after editing their delayed coverage of the London 2012 opening ceremony to replace the "memorial wall" tribute section with a Ryan Seacrest interview with Michael Phelps.

NBC, exclusive holders of the US rights to the Games, chose to broadcast the entire ceremony on a time-delay to maximise primetime advertising revenue, and were further criticised for refusing to provide a live online stream.

NBC's broadcast, which began as the live ceremony was finishing in London, left out sections including the reflective moment when the Scottish singer Emeli Sandé sang Abide with Me.

The section included images of loved ones lost by those in the stadium, and was also widely interpreted as a tribute to the 52 victims of the 7/7 terrorist attacks in London in 2005.

On the BBC's coverage, commentator Hazel Irvine said: "The excitement of that moment in Singapore seven years ago when London won the Games was tempered with great sorrow the very next day, with the events on 7 July."

However NBC instead cut away in order to show Seacrest, the host of American Idol, interview Phelps.

Criticism of NBC's handling of the broadcast rights comes after it revealed its advertising income from the event has passed $1bn (£630m). It earned $850m from the 2008 Beijing Olympics.

In reaction to complaints over the lack of a live stream from the ceremony, NBC said: "We are live streaming every sporting event, all 32 sports and all 302 medals … The opening and closing ceremonies, however, are entertainment spectacles.

"Our award-winning production team will present them on a medium that best demonstrates their grandeur and majesty, and at a time when friends and family are able to gather together to watch, which is in primetime."
