A company called the Nielsen Ratings does the ratings for local and national television.
They survey a very small part of the population. A small box on viewer's televisions records what the viewer watches. They then use this statistical sample to determine how many people watch a show nationally.

some take polls...thay call about 100 to 500 people and ask. then they calculate, using statistics, the POSSIBLE number of people watching. others use electronics to detect which channel your tv is tuned to, then again calculate the possible number of watchers
