Come to think of it...

It occurred to me yesterday, as I was drifting off, that I had read an article somewhere about how the statistic of "number of people who watched a recorded show within 3 days" had become a factor in the ratings calculations, which basically means that as DVRs become ubiquitous—and that's far from a given quite yet—the tactic of attempting to erode the competition's market share by pitting shows against each other in the same time slot is (or ought to) become useless.

Except possibly in the area of commercials, which you pretty much have to endure if you want to watch a show as it is being broadcast (and frankly, I don't and do not know of anyone who goes to the trouble of recording a one-hour show and then starting to watch it fifteen minutes after the start of the broadcast just to be able to skip the ads).
