This is huge for American exposure for that series. It's not something I had an entree into, so I've never followed it closely. This will make it much easier to watch casually than it being on an obscure and hard to find network.
I'm not always a big fan of NBC's style of presentation, but I'm glad there is a major network placing such emphasis on a variety of motorsports.
Are they going to have American announcers, or will this be an ESPN F1-esque international simulcast?
