The Full form of TRP is Television Rating Point. TRP is a tool which indicates the popularity of a program on the television. 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 viewers. Its data is very useful for the advertisers because, they place their advertisements during the programs with higher TRPs. For calculation of TRP, a device is attached to the TV set in a few thousand viewers’ houses for judging purpose. These numbers are treated as sample from the overall TV owners in different geographical and demographic sectors. This device is called as People’s Meter. It records the time and the programme that a viewer watches on a particular day and the average is taken for a 30-day period which gives the viewership status for a particular channel. Another technique to calculate TRP is Picture Matching Technique, 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.
