So when it came time in the opening ceremony for something that has been widely interpreted as a tribute to the 52 victims of terrorist attacks in London in 2005, it’s not shocking NBC didn’t see lingering on that as helping its overall marketing effort. When asked why NBC didn’t show the memorial, NBC spokesman Greg Hughes on Saturday said only that “our programming is tailored for the U.S. audience. It’s a tribute to (opening ceremony producer) Danny Boyle that it required so little editing.”
