What is Television Audience Measurement?

TV audience measurement is one of the most important parts of media research. Without proper TV audience measurement, it would be impossible to learn about the viewing habits of the average TV watcher. Data has a lot of importance nowadays as it can help us learn things that we didn’t know in the past. The information that is gathered through TV audience measurement can be extremely valuable and it can help content creators to plan their approach. It is through TV audience measurement that people can determine the price of ads at a certain point.

How is TV Viewership Measured?

One of the best ways to calculate TV viewership is through population sampling. Through this method, researchers can record what a few people are watching at a given point in time, and they apply that information on a large population. This is also what Nielsen does; they choose a subset of people from a large population and filter out the people depending on their needs. This gives them an estimate of the demographics of the viewership. With this method, they can learn about viewing habits of people coming from a specific age group, ethnicity, or even gender.

All of this information can be extremely helpful, and that is what makes TV audience measurement so important. Something that makes TV audience measurement so unique is that it is very reliable, and the data is highly transparent.

How are Nielsen Ratings Determined?

There are two primary methods that Nielsen uses to collect viewership data. One is known as viewer diaries where members of a certain household record their own viewing habits. However, this method was slowly phased out as it was not as effective. The other method that is now widely used is known as set meters, which are essentially small devices that are connected to the television, and they gather all of the required data on their own.

The main way through which Nielsen ratings are calculated is on a sample of 40,000 homes, which makes up about 100,000 people. This is a very small sample size, but it is all that is needed. The ratings are then calculated in percentages, and they measure a certain group of people. This division can be made on the basis of age, gender, or ethnicity. The main demographic uses are based on adults ranging from the age of 18 to 49, and ad rates are set with this demographic in mind.

TV ratings are very important, and it raises the questions of what is a good rating? To simply explain this, if a large number of households are watching a particular channel or show, then it means that the ratings are good. The lower the viewership, the lower the rating is going to be. So, content providers work very hard to make sure that their viewership remains at the top.


These were some of the main things that you need to know about TV audience measurement. Gathering all of this data is hard work, but it is also extremely rewarding at the same time. It is through proper TV audience measurement that media companies can maximize their profits. Once they know the times of day at which the highest number of people watch TV, they can charge accordingly. Media creators, on the other hand, want to make sure that their content is shown at the right time to increase profits. The timing changes from show to show; for example, if a particular show is targeted towards kids, it will probably be shown during the day.
