Which is bull... the ads aren't reaching us even when we do watch :). These guys are just playing with probabilities, they have no facts at all.

BTW, is the rating system the main reason why nothing ever happens on TV that was accidental? Why there is no live TV at all? Even what is live is staged. When was the last time something unscheduled happened and was let to be seen on TV (not counting 9/11, which is only a measure of how strong an event has to be to break this "no surprises" rule)?
