The rating systems are essentially polls run by Nielsen, Arbitron, and others. Like other polls, they are based on a random selection of households. There are two basic ways that ratings are done. One way is by diaries in which the residents of the selected households record which shows they are watching in a logbook. The other way is by a monitor attached to the tv/cable box that records what channels are being watched.
Everything else being equal, higher ratings equal higher ad revenues. However, most ad agencies are more concerned with ratings within specific demographic groups than with the overall ratings. For example, the largest segment of movie-goers are in their teens and early twenties. Thus, a studio that is releasing a movie on Friday will want to advertise on the Thursday night show that has the highest ratings among teenagers which may not be the show with the highest overall ratings. From that point, it is basic supply and demand. The shows with the best demographics have the most demand for ad slots and thus get to charge the highest ad rate.
I am not sure how ad revenue works between the networks and the affiliates. My general understanding is that the affiliates get some compensation from the networks. How much of that compensation is cash and how much is an ad slot or two during the commercial breaks (which are typically around four ads long)) I don't know.

The first part of the first answer is basically correct. The only thing I might add is that the households, which are selected to keep a log of what they watch or the households with a monitoring device attached to their TV sets are sworn to secrecy. They are not allowed to tell anybody that they do it. They could be your neighbors, but you do not know they participate in this. That's why it seems nobody "reports" what they watch.
And there's a third way to find out what's being watched. Sometimes those "rating companies" just call randomly and ask: "What are you watching now?"

Believe it or not, Nielson uses a nationwide sample of between 500 and 800.
They give each "Nielson Family" a box that tells them what's being watched-- or what's tuned into-- on each TV in each house, but they rely more on viewing diaries kept by their paid viewers.
This helps them sort between what is actually being watched and what just happens to be playing when the TV's on.
By the way: the sample size is ample, as it is likely to repeat again and again as you double it, or try to flag every TV in the nation.
Local ratings veer wildly from national numbers: here in L.A. the top five shows have been La Bella Mas Fea for the last year (the Mexican telenovela upon which "Ugly Betty is based).

The Nielsen company monitors tv programs for the networks.
They use "Nielsen Families" that have a box connected to the TV that gathers information about each program a Nielsen family watches.
The Nielsen Company reviews the data, which they give to the networks networks so they know which shows are popular and those that are not popular.
