TRP stands for Television Rating Point. It is a tool which indicates the popularity of a television program. It is used to judge that which television program is viewed most. This gives an index of the choice of the people and shows the popularity of the particular program. A program with higher TRP indicates that the program is viewed by a large number of viewer. Its data is very useful for the advertisers because, they place their advertisements during the programs with higher TRPs.
Presently, INTAM (Indian Television Audience Measurement) is the only agency which is working in the area of TRP calculation.
It works on two methods:
To calculate TRP in this method, A device is attached to the TV sets of few thousand viewers' houses to judge. This device is called People's meter and records the time and the program that the viewer watches on a particular day. After that an average is taken for 30-day period to know viewership status. People's meter is a very costly device which is imported from abroad.
In this technique, People's meter is continuously records a small portion of the picture that is watched on a particular television set. After that data is collected from the sample homes and used to calculate the national rating. This technique is more reliable and comparatively new in India.
