Aqumena Review

For decades, media measurement was largely something marketers bought from established currencies, platforms and research suppliers. Halo, Aquila and Origin signal a change. Advertisers are increasingly defining the measurement problem themselves, setting standards and governance, and creating the research, technology and media ecosystem needed to solve it. @World Federation of Advertisers

The immediate frustration is surprisingly basic. Marketers still struggle to answer, consistently across television and digital platforms, how many different people a campaign reached, how often each was exposed, where audiences overlapped and which channel added incremental reach. WFA says fragmentation has made credible reach-and-frequency calculation extremely difficult. @Origin Media Measurement adds that platform and publisher reporting is siloed and built on different identifiers and methods, making “apples-to-apples” comparisons difficult and creating duplication and excessive frequency.

The first use case is cross-media campaign accounting: deduplicated reach and frequency across channels and platforms. The second is campaign optimisation—identifying which partners add unique reach, which duplicate existing audiences, and where frequency becomes wasteful. Third comes planning: using comparable evidence to decide channel mix and investment. A fourth, still emerging, is effectiveness and outcomes. WFA says that the 2026 work by @Halo includes research into outcome studies and broader analytics, showing that the ambition is moving beyond exposure measurement, but that capability is not yet the mature core.

Advertisers are not building all this alone. WFA identifies Kantar Media and Accenture as common partners supporting the UK and US implementations. In Britain, Kantar built and operates Origin’s single-source panel, while Accenture built the technology platform. Origin also uses direct data from media platforms: its methodology explicitly references Meta and Google, while its wider stakeholder roster includes Amazon Ads, TikTok, Sky, Samsung Ads and Pinterest alongside agencies and advertisers.

The methodological centrepiece is WFA’s open-source Halo framework. It combines privacy-safe event-level data from media owners with a “Virtual Persons” approach. Origin uses a Kantar panel of 2,500 UK homes to measure linear TV, digital video and display exposure. Those observations train a model representing roughly 55 million UK adults. Platform impressions are assigned anonymously to virtual person IDs, enabling cross-platform deduplication and correcting for co-viewing, shared devices, logged-out use and inaccurate demographic data. Origin also measures TV second by second and subjects the system to independent audit.

The programmes are at different stages. Origin is the most advanced: WFA described it in December 2025 as being in “Expanded Availability”, covering more than 60% of UK advertising spend, and its current site presents a functioning reporting service. @Aquila entered advertiser trials in Q4 2025, with WFA expecting progress towards product-market fit during 2026; however, Aquila’s current homepage still says “Coming soon”, so these sources do not establish full commercial availability. Halo is therefore proven as a reach-and-frequency architecture, but its broader promise—more media, richer analytics and outcomes—remains work in progress.

That explains why marketers are taking charge: to create a neutral, comparable and privacy-safe evidence base that serves buyers’ decisions rather than the reporting conventions of individual sellers.

Marketers are first taking control of the measurement currency, rules and infrastructure for cross-media exposure. The next frontier is linking that exposure consistently to effectiveness and outcomes.

Traditional systems tend to ask: “How many viewers/users did this medium or platform deliver?”

The advertiser-led framework instead asks: “What did my campaign deliver to people across the entire combination of media I bought?”
