This document summarizes a seminar on audience measurement and TRP. It defines TRP as the number of TV sets tuned into a particular program out of the total number of households with access to TV. It describes how TRP is calculated using people meters installed in sample households. While TRP is useful for networks, advertisers, and media planners, it can also incentivize manipulative practices and has limitations due to sampling errors and lack of coverage in rural areas. Overall, TRP is an important currency for the TV industry but requires improvements and oversight.
