Is Your BVOD Investment Delivering Genuine Value?

With viewing habits continuing to evolve and more advertising investment moving into Connected TV (CTV) and streaming environments, understanding BVOD’s role has become an essential consideration for UK advertisers.

Drawing on extensive industry research and our own experience auditing media investment, we have highlighted key findings and, more importantly, what they mean. While the evidence clearly demonstrates BVOD’s effectiveness, we believe the bigger opportunity lies in ensuring every pound invested is planned, traded, and measured as efficiently as possible.

Broadcaster Video on Demand (BVOD) has evolved from being an extension of traditional television into one of the most valuable components of modern video advertising. Platforms such as ITVX, Channel 4 Streaming, and Sky now play a central role in helping advertisers reach increasingly fragmented audiences while maintaining the quality, trust, and scale associated with premium broadcast television.

Industry research involving Channel 4, ITV, Sky, PwC, Gain Theory, and GroupM demonstrates that BVOD is no longer simply an add-on to Linear TV. It is an increasingly important driver of incremental reach, stronger campaign effectiveness, and more predictable returns on investment.

At 23 Media Audits, we believe the findings reinforce an important point for advertisers: investing in BVOD is only part of the equation. The real opportunity lies in ensuring campaigns are planned efficiently, bought competitively, and measured correctly.

Consumer viewing habits have shifted significantly over the past decade. Viewers increasingly expect the flexibility of on-demand viewing but still value professionally produced, trusted content delivered by established broadcasters.

Unlike many open-web video environments, BVOD combines:

• Premium broadcast-quality content;
• Large-screen viewing in the home;
• Higher levels of viewer attention;
• A controlled advertising environment with minimal fraud and brand-safety risk.

For advertisers, these characteristics create an environment where commercial messages are far more likely to be noticed, remembered, and trusted.

Large-scale econometric analysis covering more than £1 billion of advertising investment found that campaigns combining Linear TV and BVOD can generate up to 10% higher ROI than using linear television alone.

The research also showed that BVOD delivers one of the most consistent returns across all video channels. While some digital channels can produce exceptional individual results, they also display far greater performance variance between campaigns.

Predictable performance allows advertisers to forecast outcomes more accurately and reduce investment risk, particularly when marketing budgets face increased scrutiny.

One of BVOD’s greatest strengths is its ability to extend campaign reach beyond traditional television audiences.
Research found BVOD delivers, on average:

• 4% additional Adult (16+) reach
• 6% additional ABC1 reach
• 8% additional reach among 16–34-year-olds

This additional audience is largely driven by light Linear TV viewers - people who watch relatively little scheduled television but consume significantly more broadcaster streaming content.

For advertisers seeking to maintain television-scale reach while younger demographics fragment across multiple platforms, this incremental audience is indispensable.

The research highlights several planning principles that consistently improve campaign performance, including:

• Running BVOD campaigns for longer than 30 days;
• Using multiple broadcaster sales houses rather than relying on a single supplier;
• Spreading activity across a broad range of genres;
• Extending delivery across wider dayparts;
• Aligning campaigns with premium programming where appropriate.

These are sensible recommendations—but they also raise a critical question: How many advertisers actually verify that these planning principles were executed?

Media owners naturally focus on demonstrating the effectiveness of their platforms. Our role is different: we help advertisers verify whether they are extracting the maximum possible value from those platforms.

When reviewing BVOD investment, we examine:

• Was the optimal balance achieved between Linear TV and BVOD?
• Was true incremental reach delivered, or was budget wasted on excessive frequency?
• Were agreed target audiences reached efficiently?
• Were campaigns delivered across the planned sales houses and quality environments?
• Was inventory purchased at competitive commercial benchmark rates?
• Were any unnecessary data or targeting premiums paid?
• Did post-campaign reporting match contractual commitments and delivery guarantees?
• How did BVOD contribute to overall business outcomes rather than isolated channel metrics?

Answering these questions regularly reveals significant efficiency gains and cost recoveries that standard agency reporting overlooks.

As BVOD budgets grow, advertisers require greater transparency across trading, placement quality, and delivery.

Independent media auditing provides board-level confidence that:

• Budgets have been deployed strictly according to brief;
• Contractual and commercial terms have been fully honoured;
• Delivery matches agreed targeting criteria;
• Reach and frequency objectives have been achieved without wasteful overlap;
• Performance is audited impartially, rather than judged solely through self-reported platform metrics.

Ultimately, BVOD should be held to the same standards as every other media channel: judged not merely by impressions served, but by the tangible commercial value delivered to the advertiser.

Industry evidence confirms what many advertisers already know: BVOD is now a core pillar of high-performing video planning. It combines premium viewing environments with proven incremental reach and dependable returns.

However, as budgets shift further into Connected TV, advertisers must ensure every pound spent delivers maximum commercial return.

The question is no longer whether BVOD works. The question advertisers should be asking is whether their BVOD investment is working as efficiently as it should.
