Who measures TRP in India?
BARC India, the Broadcast Audience Research Council. It is an industry body set up by broadcasters, advertisers and advertising agencies, and it has released TV ratings since April 2015. BARC places meters in a sample of homes and projects the viewing to all TV homes.
How do advertisers use TRP?
Media planners add up the ratings of every spot in a campaign to get GRPs (gross rating points). They then compare channels on CPRP (cost per rating point): how much it costs to reach 1% of the target audience.
A made-up example: a spot costs ₹40,000 and delivers a TRP of 2 among women aged 25 to 44 in West Bengal. The CPRP is ₹40,000 ÷ 2 = ₹20,000. Another channel's spot costs ₹25,000 for a TRP of 1, so its CPRP is ₹25,000. The first spot is the better buy for that audience, even though it costs more.
TRP vs reach
- TRP tells you what share of the audience watched at a point in time.
- Reach tells you how many different people saw your ad at least once over the campaign.
- Frequency tells you how many times, on average, each of those people saw it.
