Baz, this thread will get moved to current events when the riots and bombings start, the athletes start dropping dead from the filthy air, the Bird's Nest stadium collapses from crappy workmanship..
You missed most of the NBC "logic"--what will be shown in the US is "sports" women who don't watch real sports want to see as long as it involves US athletes. However, NBC did include Telemundo in the coverage, so if you want to see football coverage, you should be able to get the Spanish language version.
At least the men's 400 meter run should be shown live.
I always look forward to the final lap of the 800m when they cut away to some heart wrenching story of one of the US team's family members in hospital or something.
