In terms of reach, I think they both hit about 80-85 million homes currently.
As for the swap from Speed to NBC, it doesn't change anything for me. I'm never awake early enough to watch live coverage on Speed, and I end up downloading the BBC or Sky coverage anyway. I am a bit disappointed to see Will Butxon without a job in 2013 (currently). Always love his coverage when I do see it and it'll be a shame if he's not picked up somewhere.
