What is TRP? 

TRP is Television viewers rating points declared every Friday to the channels by TV Audience Measurement (TAM) media research. It is a tool provided to judge which television programmes are viewed the most on which AD rates for a program is decided. 'People meter' are installed in about 5500 sample homes and these electronic gadgets continuously record data about the channel watched by the family members and the agency prepares a national data on the basis of its sample homes readings. The instrument is able to digitally record as to which particular channel is being viewed at a particular point of time and for how long in such TV homes. More than Rs. 20 crore are spent annually on measuring TRP.

Basically a good TRP brings better AD prices, which all TV Channels want and work for. Many skeptics have doubted on its result representing all sections of people. But its just an approximation. An after the advent of DTH, the inability of TAM to measure correct TRP has posed some question on its result.

How is it calculated?

Terminology:
Universe: Total number of people in a defined target audience or area.
Reach: Reach is the no. of individuals from the universe (targeted area) who are exposed to the medium.

Calculation of Reach:
If universe consist of 100,000 People,for a single episode of a show of 30 minutes, and if 60,000 out of above 100000 people watched at least 1 minute of programme then:
Reach = (60,000/100,000) x 100
Reach = 60%

TRP = Reach x Time spent
