I'd like to make two comments about the Let's Run analysis of the ratings:
1) I suspect that the two broadcasts (OT Marathon and NYCM) were watched by many of the same people, but that there was likely a group that chose not to watch a NYCM w/o top American male contenders.
2) I also expect that for many people, the short broadcast format probably hurts ratings. I don't know if I'm unusual, but when I channel surf and hit something of interest, like running, I stay there, thus, by not having enough time to draw surfers in, ratings get hurt.
Hey, Let's Run, did you have Neilsen look 1/2 hour by 1/2 hour at ratings of any of the races?
