BARC India is the organisation that measures television audiences in India and provides the ratings data underpinning all linear TV advertising. Here are the key facts:
- What it is: A joint industry body owned by India's broadcasters (IBF), advertisers (ISA), and agencies (AAAI). All three sides use it as the common measurement currency.
- How it works: A people meter panel — BAR-O-Meters installed in tens of thousands of representative Indian TV households. Devices detect what's playing (via inaudible audio watermarks) and who's watching (household members register with a button press).
- What it measures: All major linear TV channels in India — Free-to-Air and Pay TV, national and regional, in all languages. Every Star, Sony, Zee, Colors, Sun, and regional channel that carries the BARC watermark.
- The data products: Weekly ratings published every Wednesday. Programme-level and channel-level audience data. Used for GRP buying, CPRP calculations, and reach/frequency planning on linear TV.
- CTV limitation: BARC was built for linear TV. Its streaming/CTV measurement is partial — not all platforms participate, and coverage of individual streaming apps is incomplete. CTV planners cannot rely on BARC data the way linear TV planners do.
