It pretty much says that the Olympics, at least in America, have become a huge reality show series. It's sooooooooo true and sad. NBC is extremely jingoistic, and doesn't give a shit about any other country. It's supposed to be an INTERNATIONAL event!!!!!!!!!!!!!!!
I know the "cool" thing these days is to have no patriotism for your country, but I personally have no problem with NBC having a US bias. They're broadcasting to the US. Is it shocking that they're rooting for the Americans?
If I was watching the game in Hungary, for example, I would expect a bias in coverage toward Hungarian competitors. It's only logical, and to go so far as calling it "jingoistic" is I think a bit extreme. On the contrary, I'd find it rather bizarre if their networks spent all their time talking about Phelps instead of Laszlo Cseh, for instance.
The Olympics are certainly an international event, but they are also a national showcase. I think if there's not at least a modicum of nationalistic pride involved, "you're doing it wrong". These games should make us all feel proud of our respective countries, and I think it's fine for the networks to get a bit caught up in that sentiment.
That said, I do share your disgust with NBC's general broadcasting quality, what with adding as much drama as possible to the proceedings. I'm also still irritated by tape delays, but at least they are providing a live stream over the web. I've enjoyed watching the swimming events live on the internet rather than having it spoiled through twitter before being able to see it on the delayed evening broadcast.
Overall though, I think it's been an excellent Olympics. I especially enjoyed the biking early on, where a great deal of London was showcased as the competition went on.
