Ratings, ratings? Is viewership share the same as viewership?

According to the "Radio and Television Dictionary", the ratings refer to the percentage of the number of people (or households) who watch a certain program in a certain period of time to the total number of viewers (or the total number of households), that is, the ratings The number of people (or households) who watch a certain program and the total number of viewers (or total households). Ratings are divided into household ratings and individual ratings, and in general, household ratings are greater than individual ratings.

Liu Yannan, a professor at the Beijing Broadcasting Institute and deputy director of the Institute of Television Communication, said that at present, the practice of using the number of people rather than the number of households as the statistical standard in the industry is more common, and Liu Yannan's "TV Ratings Analysis——— Investigation, Analysis and Application" is the first monograph on systematic research on ratings in China.

At present, there are two methods of rating data collection, namely the diary method and the personnel meter method. The diary method refers to the method of collecting viewing information by filling out diary cards by all family members aged 4 and above in the sample household. Each household member in the sample had their own diary card, and they were asked to record their daily TV viewing (including the channels they watched and the time slot) on their diary card at all times.

The time interval listed on the diary card is 15 minutes. Each diary card can record the viewership for a week.

The personnel measuring instrument method refers to the method of using the "personnel measuring instrument" to collect TV viewing information, and it is the latest international ratings survey method. Each member of the sample family had their own button on the handset, and there was also a guest's button. When a family member starts watching TV, they must first press the button on the handset that represents themselves, and then press the button when they are not watching TV.

The measuring instrument will store all the information of watching TV in a time period of minutes (even accurate to the second), and then transmit it to the central computer of the headquarters through the ** line (or through the handheld computer to access the data).

How long will it take for the ratings to come out? Some are for a week, some are two weeks, and some are for a day. Liu Yannan said that it mainly depends on what kind of measurement method is used, if the diary method is used, because to collect and analyze the data, it takes a week at the earliest, and generally two weeks; If the personnel measuring instrument method is adopted, because the first line can return the data in real time, it can provide ratings data every other day, but the cost of the personnel measuring instrument is relatively high.

Ratings can be a percentage or a thousand. It refers to the number of people who tune in to a program as a percentage of the total number of viewers in a given time period, and it is important to note that the total number of viewers here does not refer to the number of viewers who watched the program, but the total number of all TV viewers over the age of 4 in the entire survey area.

Not a concept.
