USA tv broadcast schedule

Forgive me if there is already a thread for this but does anyone definitely know which channel(s) will be airing the Grand Prix, etc.?

I see that my local NBC station will air GP-Russia next week but I'm not sure about NBC's other channels specifically their new Olympic Channel.

Thanks.
