  • For TRPs it does not matter what the entire country is watching, but essentially what the 45,000 odd households, that are supposed to represent the TV viewership of the country, have watched.
  • Mumbai Police Commissioner Param Bir Singh said that police are looking into a scam about manipulation of TRPs (Television Rating Points) by rigging the devices used by the Broadcast Audience Research Council (BARC) India, which has the mandate to measure television audience in India.

What is TRP?

  • In simple terms, TRPs represent how many people, from which socio-economic categories, watched which channels for how much time during a particular period. This could be for an hour, a day, or even a week; India follows the international standard of one minute. The data is usually made public every week.
  • A consultation paper about television audience measurement and ratings in India floated by the Telecom Regulatory Authority of India (TRAI) in 2018 defined its importance as: “On the basis of audience measurement data, ratings are assigned to various programmes on television. Television ratings in turn influence programmes produced for the viewers. Better ratings would promote a programme while poor ratings will discourage a programme. Incorrect ratings will lead to production of programmes which may not be really popular while good programmes may be left out.”

What is BARC?

  • It is an industry body jointly owned by advertisers, ad agencies, and broadcasting companies, represented by The Indian Society of Advertisers, the Indian Broadcasting Foundation and the Advertising Agencies Association of India. Though it was created in 2010, the I&B Ministry notified the Policy Guidelines for Television Rating Agencies in India on January 10, 2014 and registered BARC in July 2015 under these guidelines, to carry out television ratings in India.

How is TRP calculated?

  • BARC has installed “BAR-O-meters” in over 45,000 empanelled households. These households are classified into 12 categories under the New Consumer Classification System (NCCS), the so-called “new SEC” adopted by BARC in 2015, based on the education level of the main wage earner and the ownership of consumer durables from a list of 11 items ranging from an electricity connection to a car.
  • While watching a show, members of the household register their presence by pressing their viewer ID button — every person in household has a separate ID — thus capturing the duration for which the channel was watched and by whom, and providing data on viewership habits across age and socio-economic groups. The panel chosen to capture TRPs must be representative of the country’s population, and the methodology must be economically viable for the industry.

How can TRP data be rigged?

  • If broadcasters can find the households where devices are installed, they can either bribe them to watch their channels, or ask cable operators or multi-system operators to ensure their channel is available as the “landing page” when the TV is switched on.
  • For TRPs, it does not matter what the entire country is watching, but essentially what the 45,000-odd households supposed to represent TV viewership of the country have watched. Broadcasters can target these households to fudge actual viewership data.
  • In the 2018 consultation paper, TRAI said: “One of the biggest challenges has been the absence of any specific law through which the agents/ suspects involved in panel tampering/infiltration could be penalised”. It noted that BARC “has filed FIRs in various police stations against the agents/ suspects involved in panel tampering/infiltration” but its efforts “to mitigate panel tampering/ infiltration have been hampered due to absence of any legal framework”.

How does panel tampering affect TRPs?

  • TRAI mentioned “panel infiltration has a significant impact when the panel size is smaller” and “with the increase in panel size, infiltration of panel homes becomes challenging”.
  • In the current case, an FIR was filed against employees of Hansa Research, which BARC hires for certain field jobs like going to panel households. BARC hires multiple agencies so that no single agency has the entire map of panel households across the country.
  • For instance taking the example of English TV news, which has a small share of the national viewership pie at around 1.5%, which means that for around 45,000 panel households, around 700 households will contribute to the viewership. “What actually happens is that while your sample is around 700, not all of them are watching English TV news every day. Actual watching will be around 350 homes.” In such a scenario, “if someone manage to rig 10 among the heavy viewing homes, then one can swing the needle big time”.
  • When the sample is smaller, “manipulation becomes easier”. In a genre like English news, “because fewer homes will have larger weightage, change in behaviour of one home gets amplified at a much larger scale nationwide”.
  • Additionally, as each channel tries to project itself as a market leader in a particular segment, it slices the data into socio-economic brackets on the basis of NCCS, age, gender, time slots (primetime) etc to find the perfect data slice. This too increases relative error in the data, because of the small sample size.

How often have allegations been made?

  • For over a decade, questions have been raised by people from within the industry. 
  • Two years ago, the I&B Ministry had raised concerns that BARC was under-reporting viewership of Doordarshan, and floated the idea of chip-based activity logs through all set-top boxes. The idea was finally rejected.
  • In 2017, the editor of one of the top five English news channels had written to BARC about how a few households from Gujarat were contributing heavily to a rival channel’s overall viewership.
