Dentsu's 'The Brand Reset': Digital Video Finally Gets Its Brand-Building Proof

Introduction

For years, Indian CMOs have faced the same boardroom battle: justify long-term brand investment when the CFO only wants to see clicks, conversions, and cost-per-acquisition. Performance marketing has dominated budgets while brand building has been quietly defunded. Now, a landmark global study from Dentsu, developed alongside Kantar and Lumen Research, is handing marketers the quantitative ammunition they've long needed. The findings don't just challenge industry assumptions — they dismantle several of them entirely.

What Just Happened

Dentsu has released 'The Brand Reset' — described as the industry's largest dataset of its kind — establishing, for the first time, a measurable and quantified connection between attention, brand equity, and both short- and long-term sales outcomes.

The study analysed ten next-generation video platforms alongside Linear TV across the US and UK, building on Dentsu's earlier Attention Economy research. Its core mission: to prove, with hard numbers, that brand building through video generates real commercial returns — not just feel-good metrics.

The headline finding is striking. A single exposure to a brand's video advertisement can generate an estimated 1% to 5% increase in brand sales over a three-year period compared to no exposure at all. That's not a campaign. That's one impression — delivering multi-year commercial value.

Amit Wadhwa, CEO of Dentsu Creative and Media Brands, South Asia, noted that the study brings clarity to attention as a driver of long-term brand growth, and positions brand building and performance as outcomes that can be pursued together rather than traded off against each other.

What This Means for Your Brand

The implications for Indian marketers are immediate and significant — across three key areas.

Connected TV is no longer Linear TV's poor cousin. The study confirms that CTV environments can now deliver brand-building outcomes broadly comparable to Linear TV. For Indian brands navigating the rapid migration of audiences to platforms like JioHotstar, YouTube, and Netflix, this is a fundamental shift in how CTV inventory should be valued and planned.

Short-form video deserves a seat at the brand-building table. One of the most persistent myths in Indian digital marketing is that short-form content — Reels, Shorts, pre-roll — exists purely for performance and awareness metrics, not genuine brand equity development. The Brand Reset directly challenges this, demonstrating that digital video including short-form formats can produce multi-year brand impact.

Skippable isn't synonymous with ineffective. The research reveals a nuanced truth: while skippable ad formats deliver lower impact at very short viewing durations, they can actually outperform non-skippable formats when viewers voluntarily choose to keep watching. For Indian brands obsessing over forced-view formats, this reframes the creative brief entirely — the goal is to earn attention, not impose it.

Contrarian thought: The study is based on US and UK data. Indian audience behaviour, platform ecosystems, and purchase journeys have distinct characteristics. The directional findings are highly relevant, but Indian brands should validate these insights through local attention research before wholesale budget reallocation.

The Numbers Behind the News

The data points from The Brand Reset are worth bookmarking for your next marketing budget presentation:

A single video ad exposure can drive an estimated 1%–5% sales increase with that brand over three years. Attention delivers diminishing returns after approximately 20 seconds of active viewing — meaning longer formats don't automatically mean better outcomes. Voluntary attention (skippable formats where viewers choose to continue) can surpass forced attention in brand impact when sustained. The dataset has been integrated into Dentsu's Global Planner tool, enabling media teams to make attention-based decisions at a channel and format level — moving beyond legacy linear-versus-digital planning frameworks.

Marketing effectiveness expert Les Binet, who advised on the research, described the study as having re-legitimised long-term brand building in digital video, giving planners a coherent framework for understanding modern video effects.

According to Dentsu's 2025 CMO Report, marketers are simultaneously under pressure to deliver short-term results, prove long-term growth, and predict future performance with often incomplete data — a tension The Brand Reset directly addresses.

The brands.in Perspective

Indian marketing has been stuck in a false binary for too long: brand building versus performance marketing, long-term versus short-term, television versus digital. The Brand Reset doesn't just offer new data — it offers a new vocabulary for conversations that Indian CMOs desperately need to have with their boards and finance teams. The real opportunity here isn't just better media planning. It's reclaiming the budget, the ambition, and the creative confidence that brand building in India deserves.

Key Takeaways for Marketers

• One video impression can generate 1%–5% incremental sales over three years — brand ROI is real and measurable
• Connected TV now delivers brand-building effects on par with Linear TV — rethink your CTV investment strategy
• Short-form digital video builds multi-year brand equity — it's not just a performance channel
• Attention beyond 20 seconds yields diminishing returns — quality of attention matters more than duration
• Skippable formats can outperform non-skippables when viewers choose to engage voluntarily
• Dentsu's Global Planner tool now integrates attention-based metrics for real-time media planning
