A bit from my perspective here in the middle east. We watched the race with a large group of expats from both the America and Canada, some Turks plus some Dutch young people.
First of all it was funny to see that the Turks knew more about Indycar and Barrichello's arrival than the Americans knew about their own sport (calling it that for Ernest's sake).
The race started, we had our beers and bbq ready and my laptop was streaming the ABC feed online on the big screen. I had another one on my lap with live T&S. When the cars got out on the straight I was on my feet yelling GO GO GO to the screen. The ABC feed as far as I could see was silent. When you should have people calling the first passes or even the possibility of a crash, there was utter silence. After the first corner a monotone voice came on and it kind of stuck to monotone through out the race.
While I was keeping my eyes on the live T&S, the tv really didn't add to our race experience. Throughout the race it was a battle with the audience for me to keep the channel on, while the Americans wanted to watch Tiger....
It's a shame that the race was called like a figure skating event at the Olympics. As an commentator your job is to rally the audience. I'll give the example of the Tour the France, we had a radio commentator in Holland who made the event sound so exciting, but when you turned on the tv you'd just see 2 guys cycling together.
Maybe we fans should teach them and make some youtube video's with our comments? Just like the drawing competition or other competitions on here.
