What is Television Rating Point (TRP)?
- It is a metric used to measure the popularity and viewership of television programs.
- The more viewers a program has, the higher its TRP rating.
- It is calculated by measuring the viewership of a particular program over a period of time, usually a week.
- TRP ratings are used by broadcasters and advertisers to determine the popularity of different TV programs.
- According to the TRP of a TV channel or programme, advertisers decide where to display their advertisements, and investors will decide about the investment of the money.
How is TRP Calculated in India?
- In India, TRP is calculated by BARC using “BAR-O-meters” that are installed in televisions in selected households.
- It uses audio watermark technology to measure viewership of TV channels, and it also measures time-shifted viewing and simulcasts.
- These gadgets record data about the channel or programme watched by the family members or selected people. This method is called the People meters.
- In this way, some thousand viewers are surveyed in the form of justice and sampling.
- The data is then extrapolated to estimate the viewership of the entire population.
- Another method is known as picture matching, where the people meter records a small portion of the picture that is being watched on the TV.
- This data is collected from a set of homes in the form of pictures and later on is analysed to calculate the TRPs.
- The BARC releases weekly TRP results every Thursday ranking all TV channels and TV programmes.
