- TRP is the criterion that indicates the popularity of a channel or programme and this data is very useful for the advertisers.
- Television ratings provide information about the viewers TV watching habits and the socio-economic background of the audience.
- INTAM uses two methodologies for calculating TRP.
- First is frequency monitoring, in which 'people meters' are installed in sample homes and these electronic gadgets continuously record data about the channel watched by the family members.
- Second technique is more reliable and relatively new to India. In picture matching technique people meter continuously records a small portion of the picture that is being watched on that particular television set.
- Presently, TRP is based upon only a small urban sample of 5500 homes spread all over India. Most of the sample homes are situated in urban areas.
- Critics doubt as to how could this small sample truly represent the taste of Indian. That's why Doordarshan has its own ratings system DART (Doordarshan Audience Ratings).
- These points were introduced in 1986 to assess the viewership of DD programmes by IMRB.
- The TRP survey is conducted in 9 major cities of India. The data are collected on a weekly basis.
- Programme’s rating point is the percentage of panel members who viewed those programmes. One TRP is equal to one percent of TV audience. To illustrate, if Ramayana gets 75 TRPs it means 75% panel members watched Ramayana during that week.
