Screen Test

For years, India’s advertising ecosystem has operated with a fragmented view of audiences. Television had one measurement system, digital platforms had several others, and advertisers were often left stitching together multiple data sets to understand how their campaigns performed across screens. In an era where viewers move seamlessly between television sets, smartphones, connected TVs and laptops, this patchwork approach has increasingly felt outdated.

Now, the launch of Broadcast Audience Research Council India (BARC) | Nielsen ONE Ads, a cross-media measurement solution developed in partnership with Nielsen, promises to address one of the industry’s most persistent challenges—the lack of a unified measurement framework across platforms. If successful, the system could offer advertisers a single view of campaign performance across television, mobile, connected TV and desktop, potentially reshaping how media planning and buying happen in India.

But the big question remains: will this new solution finally bridge the long-standing gap between TV and digital measurement, or will the industry continue to rely on multiple currencies and datasets?

The Measurement Problem
India’s media landscape has undergone a dramatic transformation over the past decade. Viewers today consume the same content across different screens, watching a cricket match on television, catching highlights on their phones, and streaming analysis on connected TVs. Yet the systems used to measure audiences have not evolved at the same pace.

Television ratings in India are primarily measured by BARC through its panel-based system, which tracks viewership across thousands of households. Digital platforms, on the other hand, rely on a mix of platform analytics, third-party measurement tools and advertiser-side data. Without a unified measurement system, media planners often rely on approximations or multiple datasets to estimate reach and frequency. This is where the new BARC | Nielsen ONE Ads solution hopes to step in.

“Today, measurement across TV and digital is still quite fragmented, which makes it difficult for marketers to clearly understand deduplicated reach and the incremental impact each platform delivers. A unified cross media system would help solve that challenge by offering a single source view of audiences across TV, mobile, CTV and desktop. For marketers, this would significantly improve frequency management and help reduce media wastage. More importantly, it would enable far more confident and data driven decisions when it comes to planning scale and reaches across different platforms.” said Vikas Iyer, Head of Marketing, Lenexis Foodworks.

A Pilot with Cricket’s Biggest Stages
The solution is currently being rolled out through a pilot in collaboration with JioStar, starting with some of India’s biggest sporting events the ICC Men’s T20 World Cup and the Indian Premier League (IPL).

These events represent some of the most complex cross-platform viewing scenarios in India, with audiences watching live broadcasts on television while simultaneously streaming matches on digital platforms.

BARC says the pilot phase is intended to test how effectively the system can measure campaign reach across four screens: television, mobile, connected TV and desktop.
“At present, BARC | Nielsen ONE Ads is starting with a pilot in collaboration with the JioStar platform for the ICC T20 World Cup and IPL. Post IPL, we plan to expand it to other platforms and it will be offered as an “opt-in product”, i.e., a media platform would need to subscribe to it. The goal is to make it an industry-wide offering, with widespread participation from publishers/platforms and advertisers alike,” the organisation said in response to queries from IMPACT.

This means that, at least initially, media platforms will need to subscribe individually to access cross-media ratings.

The long-term goal, however, is much broader. BARC says it aims to turn the system into an industry-wide offering with participation from multiple publishers, platforms and advertisers.

How the System Works
While the industry has been discussing cross-media measurement for years, implementing it has proven challenging. The biggest hurdle lies in tracking audiences across devices while avoiding duplication ensuring that a viewer who watches content on multiple screens is counted only once in the total reach figure.

BARC | Nielsen ONE Ads seeks to address this through a unified measurement approach that combines television panel data with digital measurement methodologies.
For advertisers, this could provide a much clearer understanding of how campaigns perform in an increasingly multi-screen world.

“For advertisers, having a single and reliable source of data is important. Until now, many have relied on statistical tools and approximations to understand cross-media performance. A solution like this could help marketers make clearer and more informed decisions about their media investments. That said, one factor to watch will be the size of the sample, as it can significantly influence the accuracy and reliability of the measurement. Overall, however, it is seen as a positive development for the industry.” Said a GCPL spokesperson.

Why Deduplicated Reach Matters
One of the biggest promises of the new solution lies in its ability to offer deduplicated reach across platforms. In simple terms, deduplicated reach measures how many unique people have seen an advertisement, rather than counting each exposure separately across platforms.

Today, advertisers running campaigns across television and digital often struggle to determine how much overlap exists between audiences. For instance, the same viewer might watch an ad during a cricket broadcast on TV and then see the same ad again while streaming highlights on a smartphone.

“Audience duplication and overlap remain major challenges for marketers today. With the technology available, advertisers want to optimise returns on every rupee invested, which makes managing reach and frequency across platforms extremely important. However, traditional linear media like TV and digital platforms currently do not offer a unified way to track consumer frequency or coverage across both ecosystems. If a common framework could identify audiences across traditional and digital platforms, it would help marketers reach the right consumers with the right frequency, reduce overlaps, improve efficiency and ultimately drive better ROI and conversions.” Said Bhuvan Dheer, Executive Officer (Marketing & Sales), Maruti Suzuki.

Without deduplication, both exposures may be counted separately, inflating reach estimates. BARC | Nielsen ONE Ads aims to provide exactly that helping advertisers understand how audiences overlap across screens and how campaigns perform across different target groups.

For media planners, this could mean better allocation of advertising budgets and more efficient campaign strategies.

“Until the major walled gardens are onboarded, advertisers will have partial visibility - which is one of the core practical limitations of cross-media measurement today. The system becomes truly credible and useful only when platforms share data into a common, governed data lake, enabling a unified view of reach, duplication and exposure control. Consumers straddle TV channels, and they straddle OTT platforms too - without a common data layer, planning will continue to be siloed, and the most basic optimisation levers i.e., unified reach and frequency/exposure management remain a challenge.” said Saurabh Shrivastava, Executive Vice President - Integrated Planning & Operations, Media, dentsu India.

The Industry’s Long Search for a Single Currency
The concept of a single measurement currency has long been debated in India’s advertising ecosystem. In traditional television, BARC ratings have largely served as the standard metric for media planning. But digital media has remained far more fragmented, with platforms often relying on their own analytics systems.

From an advertiser’s perspective, efficiency has always been a key parameter. In fact, the advertising industry was earlier built around metrics like cost per impression. In television, media teams would spend hours optimising the right channel mix, spot mix, program and duration to get the best value for their investment. “In today’s omni-channel world, however, platforms often operate in silos, making it difficult for advertisers to track how many people have been exposed to an ad, for how long, or how frequently across platforms. A unified measurement tool developed collectively by industry bodies like BARC and Nielsen could therefore have a significant impact. It could help improve transparency, reduce inefficiencies and allow advertisers to optimise media spending while redeploying budgets more meaningfully to reach audiences.” said Shekhar Saurabh, Head of Marketing, TATA AIG.

By combining BARC’s television measurement expertise with Nielsen’s global experience in cross-media analytics, the new solution aims to move the industry closer to a unified measurement system.

BARC describes the initiative as an important first step toward that goal.

“The effort and goal is to provide the industry with a credible, robust, third-party unified measurement,” the organisation said.

The launch of BARC | Nielsen ONE Ads is therefore being positioned as an attempt to address one of the industry’s most persistent gaps measuring audiences across platforms and screens through a single framework.

The Road Ahead
Cross-media measurement has been a long-standing ambition for the advertising industry not just in India, but globally. As audiences increasingly move between screens, the need for a unified measurement framework has become more urgent.

The launch of BARC | Nielsen ONE Ads represents an important step in that direction. By attempting to combine television and digital measurement into a single system, the initiative could bring much-needed clarity to an ecosystem that has long struggled with fragmented data.

Yet the journey toward a true single measurement currency may still take time. Questions around methodology, industry participation and data transparency are likely to remain part of the conversation.

What happens after the IPL pilot and how many publishers choose to participate will ultimately determine whether the system evolves into a widely accepted industry standard. For now, however, the launch signals something the industry has been waiting for: a serious attempt to bridge the gap between television and digital measurement.
