It would be nice if they would put their episodes on the cbs.com site, or participated in On Demand. Especially for their Sunday night programming. It's funny, they whine about how their Sunday night at 10 pm spot is the "kiss of death" yet they insist on letting NFL and other sports nonsense run anywhere from a few minutes to two hours beyond their time slot. It's no wonder their ratings suck, and people download the episodes instead.
If they were available on their website, or via On Demand, they could at least count those viewers in the ratings. As it is, nope. People either skip it entirely, or watch through alternative, uncounted, means. And CBS has no one to blame but themselves.
