How do TV stations know their ratings? So how do TV stations make money?

Nowadays, there are many companies that specialize in this kind of statistics, such as CCTV's ratings, which are counted by Sofurui. Ratings data is a statistical method that uses statistical methods to take a partial sample of the audience as a population, and infer the overall situation based on the situation of the sample. It is generally obtained in the following ways:

1. Personnel measuring instrument: a special instrument that can record the audience's viewing or listening time, which can be fed back to the data center at regular intervals. 2. Diary card:

4. Interview: The interviewer will ask the target audience to understand the audience's viewing behavior. Due to the rapid development of the current TV ratings industry, the stability and reliability of the data obtained by these two methods are better, and the success rate of effective access is also relatively high, especially the use of personnel measuring instruments, and the objectivity of the data can be further improved.

Therefore, these two methods are more used in TV audience surveys. The latter two methods are mainly used in audience surveys on radio. In the design of the questionnaire (the personnel measuring instrument does not have a questionnaire in the strict sense, but it requires the sample households to provide background information.

For example, age, family size, income, etc.) If the main focus is on the audience's viewing behavior and trends, rather than not caring about the audience's satisfaction with specific programs and programs, then the data obtained is the ratings; If the main thing is to know how satisfied the audience is with a particular channel, program, and program, then the data is viewership satisfaction. In short, no matter which way the data is obtained, whether the data is ratings or satisfaction, the purpose is to understand the audience, and the audience's eyeballs are the main source of income. Therefore, ratings are first and foremost used to understand the needs of the audience, so as to provide guidance for programming.

Once the professional receives the ratings for each sample, they aggregate it. This data is built in a large database and then analyzed. First of all, it is necessary to analyze the trend of programs and channels, which is generally reflected in charts.

Then, under the guidance of communication knowledge, advanced statistical analysis methods are used to find out the patterns behind complex data. You can find out who is watching or listening to the program, what their social attributes are, and where the people with this social attribute are interested in the program. Thus being able to adjust the type of program, style, etc.

Make the show more relevant to these audiences.

Simply put, it's an in-film advertisement. For example, if a TV station wants to introduce imported blockbuster Harry Potter as a TV program for the Spring Festival (of course, there will also be **high-rated programs**, and the ratings will be very high during the period), the TV station will do publicity in advance and will also tell the information to the advertiser, and the advertiser will look for a company that wants to advertise during the Spring Festival. Of course, the advertising cost will also be very high during this period.

The news broadcast at 19 o'clock every night has high ratings. Some companies will pay a lot of money to buy the right to advertise at the beginning of the film, and every second is tens of thousands.
