1. What is TAM and what’s it with NDTV’s case against TAM

3. TAM Media Research is a joint venture between Nielsen (India) Private Limited & Kantar Market Research. Appointed by Joint Industry Body (JIB) which is composed of the Industry stakeholders of ISA (Indian Society of Advertisers), IBF (Indian Broadcast Foundation) and AAAI (Advertising Agencies Association of India) in 1998.

4. We measure more than 40 percent of the world’s viewing behavior—hundreds of channels, thousands of programs, and millions of viewers. This measurement breadth allows clients to plan programming and advertising for their ideal audience. That great lipstick ad you saw during your favorite reality show—that was no accident—it was informed by big data. What TAM says?

5. The system of TRPs is supposedly conveying our interests and viewing patterns to broadcasters. They are the only formal system of consolidated viewer feedback in terms of viewing patterns and preferences. Based on this research or unit of measurement, programmers, advertisers and editors are deciding what we like to watch and how

6. For example, the current system of TRP ratings is based on TV meters installed in 8,000 or so households in urban locations across most states

7. For instance, the average viewer spends around 130 minutes per day watching TV. Of this, nearly 80 percent is spent on a leading set of 30 channels. This means that the rest of the channels—anywhere from 150 to 350, depending on the DTH or cable operator—are fighting for a slice of roughly 26 minutes each day.

8. What do the TAM sample size and viewership numbers tell us?

9. When both the TAM sample sizes and viewership minutes are so insignificant, even minor manipulations in viewing can have a magnified impact on TRP ratings.

10. In its report presented in November 2010, the Amit Mitra committee laid down a roadmap for improving the system. A critical recommendation was increasing the number of Peoplemeters by around 22,000. Funding this increase in TAM’s Peoplemeter homes would entail a one-time capital expenditure of about Rs 330 crore spread over five years, plus an additional operating expenditure of Rs 330 crore a year,

11. Besides, the Joint Industry Body (JIB) that since 1997 oversaw TAM’s research and frequently questioned its data died an unnatural death around 2004. So, for the last eight years, there has been virtually no industry supervision of TAM.
