Connected TV in Europe: The Fragmentation Tax

Connected TV has been the primary source of ad views in Europe since 2024, accounting for roughly half of all video ad views — and European advertising budgets are projected to fall around 4% year on year in 2026. Those two facts together define the channel. CTV is not growing because budgets are growing. It is growing because it is taking money from somewhere else, and in a market this fragmented much of that money is absorbed by the cost of operating across too many platforms. Industry analysis calls it a fragmentation tax, and it is the central problem in European CTV rather than a footnote to it.

1. The fragmentation tax

The phrase comes from European industry analysis and it names the central operating problem in European digital marketing video budgets: in markets with stagnant budgets, investment spreads across multiple platforms, tools and measurement systems, making it harder to build reach efficiently and harder to demonstrate outcomes.

Sources: European CTV market analysis citing budgets projected at -4% year on year in 2026 and describing fragmentation as a hidden tax on CTV performance; commentary drawing on the Comcast Advertising and Longterm Colab European Market Survey, the Premion 2026 CTV/OTT Advertiser Survey and IAB Europe Attitudes to Digital Advertising 2026.

In the United States, CTV’s problem is measurement. In Europe, measurement is the second problem. The first is that you have to solve it six times.

2. Nobody in your organisation owns CTV

This is the most practically useful finding on this page, and it is organisational rather than technical. Industry commentary notes that CTV supply paths can be fragmented and opaque, making it difficult for buyers to identify how inventory is transacted, qualified and measured — and that internal ownership is also unclear, because CTV sits at the intersection of linear, digital and programmatic teams, creating inventory ambiguity.

Based on reported commentary that CTV sits at the intersection of linear, digital and programmatic teams, creating inventory ambiguity and unclear internal ownership. Team-level analysis is operational judgement.

The consequence is predictable. When a channel has no clear owner, nobody builds the cross-platform frequency management or the unified measurement that would reduce the fragmentation tax — because doing so is not any single team’s job. For European performance marketing organisations, assigning ownership is cheaper and more effective than any inventory decision.

3. The industry cannot agree what CTV means

IAB Europe’s own programmatic CTV guide is unusually candid on this point: definitions remain fragmented, terminology is inconsistent, and interpretations of what CTV and digital video actually mean differ across buyers, sellers and technology providers.

That is not a semantic complaint. If two proposals both say CTV and mean different inventory, the comparison you are making is not the comparison you think you are making.

Based on IAB Europe’s programmatic CTV guide acknowledging fragmented definitions and inconsistent terminology across buyers, sellers and technology providers. Category descriptions are general industry usage and vary by vendor — ask for the specific inventory definition in writing.

4. Forecasts disagree by more than two times

Published European growth projections for overlapping markets differ so widely that no single figure should be planned against.

Sources: European AVOD and CTV market forecasts from market research providers; IAB Europe AdEx Benchmark 2025 recording video growth of 19.6% to €34.0 billion with video exceeding half of display investment for the first time; European Audiovisual Observatory Key Trends 2026 for the total audiovisual market value. These measure different things. The 9.49% and 23.4% figures come from different providers using different category boundaries, and the gap between them is larger than most planning assumptions can absorb.

For European performance marketing planning, the defensible position is to plan against the audited single-year figure — video grew 19.6% in 2025 and now exceeds half of European display investment — and to treat six-year projections as directional at best.

5. Broadcaster VOD is the European difference

This is where European CTV genuinely diverges from the American market, and it changes what the channel is good for.

Europe has strong national broadcasters with their own on-demand services, and reported figures show broadcaster VOD growing nearly 30% in 2024 alongside SVOD consumption growth of more than 200%. Broadcasters are extending their own video-on-demand and free ad-supported streaming services, which puts premium, locally produced, brand-safe inventory in the market at national scale.

Based on reported European CTV structure including broadcaster VOD growth of nearly 30%, SVOD consumption growth exceeding 200% in 2024, and broadcasters extending their own VOD and FAST services. Usage recommendations are operational judgement.

For European digital marketing teams accustomed to the American picture of a handful of global streamers, this matters: in most European markets the strongest CTV inventory is national, not global, and it is sold by organisations with decades of television advertising practice behind them.

6. Country variation is extreme

Treating Europe as one CTV market is the fastest way for European ecommerce marketing teams to misallocate the budget. Reported 2025 data shows the spread clearly.

Sources: 2026 European AVOD market analysis reporting that in 2025, 75% of Spanish viewers consumed FAST or AVOD content weekly and 60% reported no longer watching linear television, Italian smart TV penetration of 93%, Spain’s projected 9.84% CAGR through 2031 as the fastest among countries assessed, and Russia’s isolation from pan-European programmatic infrastructure.

Six in ten Spanish viewers report no longer watching linear television. A pan-European plan that allocates Spain a traditional TV-plus-digital split is describing a country that no longer exists.

7. How to buy it without wasting the budget

If fragmentation is the tax, the response is to reduce the number of places you pay it rather than to chase every pocket of inventory. This is one of the few areas of European performance marketing where doing less is measurably better.

Operational recommendations informed by industry commentary that growth will come from better integration and orchestration rather than more inventory, and that fragmented markets argue for aggregated platforms providing access to multiple services.

8. Measuring CTV when attribution is weak

CTV shares the measurement problem described in the US analysis — household rather than person-level delivery, no click, and self-reported platform numbers — with an additional European layer, because consent constraints limit what can be joined and the definitional inconsistency limits what can be compared.

Comparative assessment. The geographic holdout is the recommendation throughout this cluster because it does not depend on consent, cookies or platform cooperation — all three of which are constrained in European ecommerce marketing.

Industry bodies including egta are reported to be promoting shared measurement standards and cross-player collaboration, and the standardisation efforts underway should gradually improve comparability. Until they do, the holdout remains the only reading that does not depend on the seller.

9. What this page does not cover

Scope statement. National landscape maps for the UK, France, Germany, Spain and Italy are published by industry press and are the right starting point for market-level supply detail.

10. The 90-day plan

Indicative sequencing. Naming an owner is first because every subsequent step requires someone whose job it is to do it, and the documented problem is that no team currently holds that remit.

11. Mistakes to avoid

Recurring errors in European CTV buying; illustrative.

12. What changes next

Standardisation is being pushed hard. IAB Europe’s programmatic CTV guidance and egta’s work on shared measurement standards are both aimed at the definitional and measurement gaps described above. Progress there reduces the fragmentation tax more than any inventory expansion will.

Format portfolios keep expanding. More European media businesses are expected to widen their CTV format offerings to sustain video ad revenue while managing viewer experience, which increases choice and, in the short term, fragmentation.

Gatekeeper regulation is an open question. Industry analysis identifies regulation of gatekeepers in the CTV sphere as a live issue for market expansion — the same DMA machinery covered in the search analysis could eventually reach device and platform layers.

Key Takeaways

• CTV is around half of all European video ad views and has been the primary source since 2024.
• European budgets are projected down about 4% in 2026. CTV growth is reallocation, not expansion.
• Fragmentation is a hidden tax paid in duplicated reach and irreconcilable reporting.
• Nobody owns CTV internally — it sits between linear, digital and programmatic. Assigning ownership is the cheapest fix available.
• IAB Europe admits the industry cannot agree what CTV means. Get inventory definitions in writing.
• Published European CAGRs range from 9.5% to 23%. Plan against audited single-year figures instead.
• Broadcaster VOD is Europe’s structural advantage, growing nearly 30% and offering premium national reach.

Frequently Asked Questions

Conclusion

Within European digital marketing, CTV has already won the argument about attention. Half of video ad views, a €142 billion audiovisual market behind it, and in some markets a majority of viewers who have simply stopped watching linear television. What it has not won is the argument about efficiency, and that is where budgets are actually lost.

The response is unglamorous. Give the channel an owner, because at present it belongs to three teams and therefore to none. Get definitions in writing, because the industry body responsible for the standards says openly that they do not yet exist. Reduce your supply routes rather than expanding them, because in a market whose budgets are contracting, every additional platform costs you more in duplicated reach and reconciliation than it returns in incremental audience. Then prove it with a holdout, and scale only what survived.
