Another reason would be satellite services - which I don’t think have “targeted” ad spots - another reason to advertise nationally on cable networks.

I noted this somewhere else. Satellite systems actually do have some targeting ability, but it isn't as finely tuned as cable. One of the ways sat systems can add target you is by downloading a slate of "national" ad content to your DVR, and then only show content selected for your locality. This is one of the reasons Satellite providers "throw in" DVR's at no extra charge.

Anyway, it isn't feasible to buy a national ad-buy just to pick up people using Satellite on a very frequent basis. It's too expensive and the dish cohort overlap with the undecided cohort is too small. By far the largest number of people who'll see the ad a) don't matter or b) have already seen it a zillion times.
