Doesn't Nielsen hook up electronic boxes to a portion of the population's televisions to register what they view, and then use those figures to project the total numbers? That was my understanding.

I dont believe so, if that was the case, if someone was watching infomercials in the morning and left to go to work with it on, the ratings for that informercial would be through the roof, even though no one was there watching it. I have only known 1 person to get a ratings review by Nielson. They had to fill in every show they watched at every time,along with every time they switched the channel and left the room,etc. I think Nielson sends out millions of these and gets them back and uses the % to see what ratings are. If they send out 10 million, and 2 million come back with everyone watching the Friends finale, they knew that Friends had a 20point share,etc...

Actually, I think they do both. There are a certain number of people (a surprisingly small number like 5000 if I remember what I read a while back) that have the boxes hooked up to their TVs. I'm sure they are coached on how to make sure the ratings are accurate, such as do not leave your TV running all day/night if you are not watching it. They also send out a bunch of surveys to different people and ask them to record by hand their viewing habits for a week or month or something. So the "Nielson Families" with the boxes are somewhat permanent and long term, but they supplement it with the surveys to a wider and varying demographic.
Our family filled out the surveys once when I was a kid, which is why all this info seems to be stuck in my brain.
