NBC did so many things wrong. The audio truly sucked. Having the sound of the track at "1" and Leah Diffy at "10" doesn't cut it. Most races my surround speakers never came on. The only time my sub would come on is for the commercials. NBC would stream FP1 & 3 on the internet and whenever I looked at it, it started late or never came on. Where I live most races start around 4 am so I'm depending on my DVR to record the races. If the race ran long, NBC would switch channels for the podium & post race. I never saw a single commercial for F1 on any channel. Since I was recording the races, I can say without exaggeration that the average of on track action was 4.5 minutes before 4 minutes of commercials.
I remember ESPN doing F1. Their commercial breaks were real short. Look, ESPN put NASCAR on the map. They advertised it constantly.
My favorite announcers was when there was a break between ESPN and Speedvision. The races were picked up (here) by the regional Fox Sports channel on a delay. The team was Derrick Bell and John Watson! Man, were those guys tough. They called out Michael Andretti saying instead of hopping on the Concorde as soon as his car died or crashed he should have put a cot up in the back of the factory.
