 :Target Rating Points:

Target rating points, or TRPs, are an audience measurement criterion that indicates the popularity of a television channel or programme. The TRP measure is very useful for advertisers, who use it to help them decide which TV channels and programmes to place their advertising in.

The TRP is a measure of the purchased points representing an estimate of the component of the target audience within the gross audience. Similar to GRP (short for gross rating point), it is measured as the sum of ratings achieved by a specific media vehicle (e.g. TV channel or program) of the target audience reached by an advertisement. For example, if an advertisement appears more than once, reaching the entire gross audience also, the TRP figure is the sum of each individual GRP, multiplied by the estimated target audience in the gross audience.

The TRP and GRP metrics are both critical components for determining the marketing effectiveness of a particular advertisement.

Collection of TV audience Measurement data in India:

Presently, INTAM (Indian television audience measurement) is the only electronic rating agency functioning in India. INTAM uses two methodologies for calculating TRPs.

The first is frequency monitoring, in which 'people meters' are installed in sample homes. People meters are electronic devices, which continuously record data about the TV channels watched by household members. The 'people meter' is an expensive piece of equipment and is currently imported. It reads the frequencies of TV channels, which are later decoded into the name of the channels. INTAM prepares national data on the basis of these sample homes readings. There is a drawback in the technique, as cable operators frequently change the frequencies of channels before sending signals to homes. It may be very misleading to read a channel according to a particular frequency even if the down-linking frequency is same all over India.

The second technique is more reliable and relatively new to India. Via a picture-matching technique, the people meter continuously records a small portion of the picture that is being watched on that particular television set. Along with this, INTAM also records all the channels' data in the form of the small picture portion. Data collected from the sample homes is later on matched with the main databank to interpret the TV channel name, in order to produce national ratings.
