My understanding is that an independent company is responsible for the measurements. They recruit X number of households who own TVs, install a black box in or near the TV, and each night, this box sends through data (to the measuring company) detailing what was watched and for how long.
Each member of the family is given a "remote". The remote is pressed by that family member when that family member starts watching something and finishes watching it.
The data collected from these recruits is seen as a subset representation of all TV watchers. The data is interpolated and ratings are calculated based on the data provided by the recruits.
Hope this helps.

The Nielson Company determines TV ratings. They measure the percentage of homes tuned into programming and also the demographics of the viewers. They sample then extrapolate to determine the "ratings" of a TV show.
People are morbid enough to watch and it gets good ratings. If television shows get good ratings more companies will be interested in advertising and the station will make money.
Nielsen ratings are the audience measurement systems developed by the Nielsen Company, in an effort to determine the audience size and composition of television programming in the United States.
They hire the Nielsen Company to measure their viewership. Nielsen uses diaries and electonic boxes to measure ratings. (No, you cannot request it, Nielsen decides).
