Nice original title(!) and contrary to what's been reported, I HAD seen much of the footage before.
Because of its quality and clarity and depth, unlike most high school and college textbooks.
It aired here in South Florida on Channel 10 on Sunday nights before ABC-TV's entertainment programming began. I never missed it and have seen every episode about a dozen times thanks to the Military Channel, DirecTV Channel 287. http://www.theworldatwar.com/ )
We knew NBC would heavily edit its broadcast of last night's London Olympics closing ceremony; they cut out a bunch of stuff from the opening ceremony, too, in the name of "tailoring programming to our American audience."
The same geniuses who DIDN'T show the medal ceremony for the Men's Marathon winner, the last contest of the Games, and always a highlight.
Me, foolishly, I thought that the hour of coverage that NBC promised us after the Local NBC affiliate newscast would be what we missed.
Instead, they re-played what they'd already run, awkwardly picking it up during the narrative of the U.S. Women's gymnastics team battle for the team gold against Aliya Mustafina, Victoria Komova and the rest of the Russian team.
In a nutshell, with plenty of examples I could cite jere, probably just like you: The winner of the Women's 100 Meters speaks English, being from Jamaica, but NBC chose not to interview her - THE fastest women in the world.
