DD's S.S. Gill and the private channels led by Star TV CEO Rathikant Basu have decided to team up on a common viewership rating system.But what are television rating points (TRPs) and how do they work? TRPs are the measure by which the popularity of programmes are judged. This, in turn, largely determines the amount of advertising the programme gets. But do advertisers really get bang for their buck? The niggling suspicion became more strident when the same programme often got wildly differing rating points from different agencies.That could be a thing of the past once the common system is set up. Most dramatic change: the sample size, which goes up to 3,000 homes instead of the current 300.Published By: AtMigration Published On: Mar 9, 1998--- ENDS ---
