The old system relied on limited samples, concentrated in urban areas, with methodologies that were rarely disclosed publicly. Broadcasters and advertisers made multimillion-rupee decisions based on ratings they could neither verify nor challenge. When disputes arose over numbers, there was no independent mechanism for resolution.
Manipulation was an open secret. Stories circulated about households being paid to watch certain channels, devices being tampered with, and sample bases being deliberately skewed. The incentives were obvious: small sample sizes meant individual households wielded disproportionate influence. Compromising even a few could swing ratings significantly.
The lack of transparency corroded trust across the industry. Advertisers suspected they were overpaying for inflated audiences. Smaller channels believed the system favoured established players. Regional broadcasters argued their true reach was invisible. Yet the industry limped along because no alternative existed.
BARC India's arrival in 2015 represented a fundamental reimagining of what audience measurement could be. Instead of a few thousand households, deploy 45,000 measurement devices. Instead of urban-centric sampling, cover rural markets, Tier 2 cities, and diverse linguistic regions. Instead of opacity, publish methodologies and make data independently auditable.
The technical infrastructure required was unprecedented for India. Building systems to process billions of viewing minutes daily, maintaining device networks across challenging geographies, and creating protocols that could detect and prevent tampering. The project demanded not just technology investment but institutional discipline to resist the pressures that had compromised previous systems.
Partho Dasgupta, who steered BARC India through its formative years, understood that transparency was not merely a feature but the foundation. "You cannot ask an industry to trust measurement data if you will not show them how that data is collected and processed," he observes. "Opacity might protect your methodology from competitors, but it also protects manipulation from scrutiny. We chose scrutiny."
The transformation was not without setbacks. Controversies over alleged manipulation emerged even within the new system, forcing continuous evolution of detection mechanisms and sampling protocols. Yet the difference was fundamental: problems were now debated publicly with data, not whispered privately without recourse. The shift from a closed system to an open one had made accountability possible, even if imperfect.
