Broadcast Audience Research Council

The Ministry of Information and Broadcasting has recently directed the Broadcast Audience Research Council (BARC) to suspend the publication of Television Rating Points (TRPs) for TV news channels for a period of four weeks or until further notice. This step has been taken due to concerns regarding the credibility, transparency, and possible manipulation of TRP data, and it indicates the government’s intent to review and strengthen the current audience measurement system.

About BARC

The Broadcast Audience Research Council (BARC) is a joint industry body established in 2010 by various stakeholders, including broadcasters, advertisers, and advertising agencies. It is headquartered in Mumbai.

BARC is the only authorized organization in India responsible for measuring television audience data. Its primary objective is to provide a transparent, reliable, and inclusive system for tracking TV viewership, which is essential for both the media industry and advertisers.

What is Television Rating Point (TRP)?

The Television Rating Point (TRP) is a quantitative metric used to measure the popularity of television programmes and channels. It reflects the number of viewers watching a particular programme over a specific period, usually a week.

A higher TRP indicates that a programme has a larger audience, making it more attractive for advertisers. Thus, TRPs play a crucial role in determining advertising rates, content strategies, and investment decisions in the television industry.

How TRP is Calculated in India

1. People Meter System (BAR-O-meters)

BARC uses devices known as BAR-O-meters, which are installed in around 58,000 selected households across India. These devices record detailed information about viewing habits, such as the channel being watched and the time spent watching it. This system is based on the principle of sampling, where data from a limited number of households represents the viewing behavior of the entire population.

2. Audio Watermarking Technology

BARC also employs audio watermarking technology, where inaudible signals are embedded into television broadcasts. These signals are detected by the BAR-O-meters, enabling accurate tracking of live viewing, recorded viewing, and simulcast content across platforms.

3. Picture Matching Technique

Another method used is the picture matching technique, in which the device captures small visual snippets from the television screen. These images are later matched with broadcast content to identify the programme being watched, ensuring additional accuracy in data collection.

4. Data Analysis and Extrapolation

The data collected from sample households is then processed and extrapolated using statistical methods to estimate the overall television viewership of the country. This ensures that the TRP ratings reflect a broader and more representative audience base.

TRP Release System

BARC typically releases weekly TRP ratings every Thursday, providing rankings of television channels and programmes based on their viewership. These ratings are widely used by broadcasters and advertisers to evaluate performance and plan strategies.

Significance of the Suspension

The suspension of TRP ratings for news channels is important because it directly impacts the advertising revenue and credibility of news broadcasters. It also highlights the need for greater transparency and accountability in audience measurement systems. In the long run, this move may lead to reforms that improve the reliability and fairness of TRP calculations in India.
