There are such things as TV meter panels (or whatever it is called in your country).
TV meter is: an electronic instrument that measures a person’s TV viewing at regular intervals, frequently on a second-by-second basis.
So there are some amount of people in your country who agreed to have those things at home.
Those people are carefully chosen to represent in a best way whole country (in a statistical way..:) )
So data from those panels are going to research center, where it is calculated.
So they have data about each member of the family (age, sex, income level, number of family members, social - professional position, level of education etc etc). For example there are thousand girls aged 12 - 18 in USA, who record their TV viewing habits and statistically they represent all girls aged 12-16 in USA.
I do not know how many TV meters are out there in USA. Probably 5-10 thousand households.. (just estimation)?
This is done mainly for advertisers. So they can find programs which are most efficiently targeting their potential customers.

and there chose Inside TV ratings.
EDIT:
this is how they do it in my country..:
there is statistical data for whole country. For example, according to official statistics there are 30% of people who are more than 50 years old in the country. Therefore also in the sample should be 30% of people who are over 50.
Or there is 52% of women and 48% of men, therefore also in sample should be 52% of women and 48% of men.
So they take as basis official statistic and making calculations based on this and then chose actual households.
Nielsen Media:
Selecting Households
Selecting a representative sample of homes is vital to collecting data that mirrors the population's viewing habits. We select households through one of two different methods: geographic selection (area probability sampling) in the national sample and larger markets, and randomly-generated telephone numbers (Total Telephone Frame) in smaller markets.
For area probability sampling, Nielsen's statistical research department begins with broad, U.S. Census-defined geographic areas. We dispatch field representatives to identify each and every housing unit in these areas, regardless of size or accessibility. Ultimately, we narrow the selection down to individual, randomly-selected housing units. Using this method, all households have an equal probability of selection into the sample. This allows for complete coverage of the country, since no homes are excluded by design.
For Total Telephone Frame sampling, Nielsen's statistical research department uses random digit-dialing to generate a call list that includes both published and unpublished telephone numbers in a Designated Market Area (DMA). Rather than using recordings, our Call Center staffs in Florida and Kentucky personally make multiple attempts to reach households, ensuring that they have a chance to be included in the sample.
