CIMM and TVB set the bar for local TV currency measurement

The Coalition for Innovative Media Measurement (CIMM) and TVB today released a formal set of guidelines for local TV and video currency measurement, establishing what the two organizations describe as baseline expectations for any measurement solution seeking to serve the local advertising marketplace. The announcement, dated May 4, 2026, and issued from New York, arrives as local broadcasters navigate a fragmented environment in which streaming, over-the-air, cable, and virtual pay TV all compete for the same audience's attention - and the same advertiser budgets.

The documents released today include two complementary pieces: a guidelines report titled Guidelines for Local TV/Video Currency Measurement - Establishing Baseline Expectations and Principles for Local TV & Video Measurement, and a companion Buyer's Guide that converts the guidelines into a structured evaluation tool for broadcasters, agencies, and advertisers assessing measurement providers. Both are available on the CIMM and TVB websites.

The problem the guidelines address

Local TV measurement has historically operated under different constraints than national television or digital advertising. According to the guidelines document, local transactions require geographic precision at the market level, measurement across multiple access points including broadcast, pay TV, streaming, and mobile, and consistency across markets with very different population sizes. These three requirements create measurement challenges that national-level frameworks do not fully address.

The guidelines were developed through CIMM's Local TV and Video Working Group, a body that gathered input from buyers and sellers across the U.S. local broadcast industry. The framework is deliberately non-prescriptive. According to the guidelines, they "outline what the market requires from currency measurement solutions while allowing flexibility in how providers meet those expectations." No single methodology is mandated. What the framework does set is a floor - a shared set of expectations that any solution claiming currency-grade status should meet.

Jon Watts, Managing Director at CIMM, framed the release in terms of shared infrastructure. "Local TV and local video remain important parts of the advertising marketplace," Watts said. "As such, the industry will benefit from having a clear, practical framework for evaluating whether measurement solutions are truly ready for local use. These guidelines are intended to help create that shared reference point."

Hadassa Gerber, EVP Chief Research Officer at TVB, addressed the gap the guidelines aim to fill. "Local market transactions have specific requirements, and those requirements are not always addressed by broader measurement discussions," Gerber said. "This work is meant to give the market a more useful standard for assessing whether local TV and local video currency solutions are inclusive, usable, and transparent."

Three principles, with technical depth

The framework is built around three pillars: Inclusive Measurement, Transactable Measurement, and Transparent Measurement. Each carries specific technical requirements.

Inclusive Measurement addresses the fundamental question of whether a measurement system actually captures the audience it claims to represent. According to the guidelines, measurement must reflect the diversity of local audiences across demographic, socio-demographic, multicultural, and geographic dimensions. Providers are expected to disclose representation gaps and explain how those gaps are addressed.

On the platform side, inclusive measurement must capture audiences regardless of how they access local TV and video. The guidelines enumerate the full access chain: broadcast and over-the-air, cable, satellite, and telecom pay TV, virtual MVPDs and streaming apps, and mobile and desktop viewing. Providers must identify which platforms are included and which are excluded, provide audience breakouts by platform and device, and clearly explain how streaming and digital viewing are measured. Market coverage must span the full range of U.S. markets - both large and small - with defined market boundaries and disclosed coverage limitations.

The Buyer's Guide translates these principles into specific due diligence questions. Among the questions posed to providers under the inclusive section: how households are represented across OTA-only, cable, satellite, telecom pay TV, vMVPD, streaming app, OTT, and internet-only access paths; how many U.S. TV markets the service measures today; and how a local TV or video market is defined, especially for streaming consumption. The guide also asks whether all outlets are reported, or only those that subscribe to the measurement service - a distinction with direct implications for the completeness of local market coverage.

Transactable Measurement covers whether a measurement solution is operationally fit for use in actual buying and selling. According to the guidelines, measurement must be stable enough to support forecasting, guarantees, and post-analysis. Providers should monitor and report stability over time, disclose standard error, provide historical data where available, and apply controls to improve reliability. The framework specifically mentions Live+Same Day as one of the key groups for which stability should be monitored across a full year.

The Buyer's Guide pushes deeper on the mechanics. It asks whether providers report standard error and for which estimates, what thresholds trigger aggregation or other reliability controls, and how much historical data is available for telecast-level impressions across commonly used demographics. On audience methodology, the guide asks whether panel-based demographic identification is self-identified, modeled, or personified - a distinction that matters considerably when panel data is used to anchor big data estimates.

Systems integration is also part of this pillar. The Buyer's Guide asks which local buying and selling systems carry the provider's data today, what automation tools are available to reduce manual error, and which transactional metrics are reported. The list of transactional metrics mentioned in the guide includes AQH (Average Quarter Hour), impressions, reach, frequency, ACM (Average Commercial Minute), and ECM (Exact Commercial Minute). It also asks how the provider defines an ad impression across platforms, and whether the service supports equitable comparison between local TV and digital - a question that directly touches the structural tension between linear broadcasting and streaming in the current marketplace.

The glossary in the guidelines document defines several of these terms with precision. AQH is defined as "the average number of viewers watching during a 15-minute period." An impression is "a counted exposure to an advertisement, defined consistently when comparing across platforms." ACR data - collected from connected TVs using content recognition technology - is included as one recognized data type alongside set-top-box data and panel data.

The guide also asks about clean room access and identity partner integration, total ad supply and ad load reporting, and current reporting turnaround times - operational dimensions that matter for day-to-day campaign management and stewardship.

Transparent Measurement is the third pillar, and it carries the most procedural requirements. According to the guidelines, providers must clearly document methodology, disclose limitations and assumptions, provide advance notice of material changes, and support auditability and engagement with the Media Rating Council (MRC) accreditation process. The Buyer's Guide asks how far in advance providers disclose material methodology changes and what impact analysis they provide alongside those disclosures.

The transparency pillar also covers how modeled outputs relate to directly observed data. The guide asks providers what evidence shows that modeled outputs are grounded in directly observed data. This question matters because big data approaches to TV measurement - combining set-top-box data, smart TV ACR data, and panel calibration - involve modeling steps that can produce different results depending on the calibration choices made.

Privacy compliance is included under transparency. The Buyer's Guide asks which current privacy regulations a provider's service complies with, how the provider monitors pending regulatory changes, and what operational safeguards protect privacy and maintain compliance. This is not a minor consideration: as PPC Land has reported on IP address accuracy research from CIMM, the infrastructure underlying audience identification in local TV measurement involves data linkages that carry significant accuracy and compliance risks.

The scoring system

The Buyer's Guide includes a "Suggested Scoring Lens" with three ratings. A capability rated "Ready now" is operational, documented, and available in market today - meaning it can support current buying, selling, and stewardship needs. A "Partial" rating means the capability exists with limits by market, audience, or workflow, and needs careful qualification before being used for currency purposes. A "Roadmap" rating means the capability is planned but not yet market-ready - useful to note, but not to be treated as live functionality.

This three-tier framework matters because several measurement providers operating in the local TV space are at different stages of development across different capabilities. A provider that has strong national measurement credentials might be only partially capable at the local market level. A provider with strong OTA measurement might have incomplete coverage of vMVPD and OTT access paths. The scoring system is designed to make these gaps explicit rather than allow them to be obscured in broad capability claims.

Authors and process

The guidelines document was authored by Joan Fitzgerald, Patti Cohen, and Matt Ross. Fitzgerald is VP Data Excellence and Privacy at the ANA and previously served as CEO of Data ImpacX LLC. Cohen brings more than 30 years of experience across broadcast, syndication, streaming, and digital platforms, including her role as Senior Vice President of Research for CBS Television Stations and CBS Media Ventures. Ross has held leadership positions at NBCUniversal, Hearst Television, and Norman Hecht Research.

The involvement of practitioners with both network and digital backgrounds reflects the nature of the challenge: local TV measurement in 2026 is not a purely linear television problem. Streaming consumption is distributed across multiple services and devices, and a measurement solution that captures only the legacy access paths misses a growing share of the local audience.

Why this matters for the market

The guidelines arrive at a moment of active competition among measurement providers serving the local TV marketplace. As PPC Land reported in April 2026, Comscore signed agreements with more than 15 broadcast clients for its local measurement products, including Allen Media Group, Cox Media Group, and Cunningham Broadcasting Corporation. Comscore achieved MRC accreditation for demographic TV metrics across all 210 measured local markets in April 2025, and completed its Joint Industry Committee certification for national TV measurement in July 2025.

At the same time, the alternative currency ecosystem is in flux. Viant Technology announced on April 15, 2026, that it would acquire TVision Insights for $40 million, gaining panel-based TV attention data. TVision had existing data licensing relationships with iSpot, VideoAmp, and Oracle that contributed to alternative currency efforts in the TV measurement market. The implications of those relationships shifting are not yet settled.

CIMM itself has been active across multiple measurement initiatives in 2026. In March, CIMM and the 4As released The Paradox of Plenty, a study of 197 senior marketers showing that advertiser measurement confidence lags capability, with 43% citing cross-platform gaps as a primary concern. In January, CIMM released an economic study examining whether the U.S. TV measurement market carries enough revenue to support multiple competing providers, concluding that basic currency services require $135 to $140 million annually while comprehensive services need approximately $250 million. Also in January, CIMM and WFA launched a research study examining cross-media measurement standards fragmentation in Europe. And in February, CIMM selected six startups for its inaugural Startup Program, covering approaches ranging from AI-powered campaign automation to real-time co-viewing verification.

Against that backdrop, the local TV guidelines represent a more foundational piece of work. Rather than addressing a specific measurement technology or data source, they attempt to define what the local marketplace needs from any measurement solution, regardless of the approach used. For agencies and advertisers buying local TV across dozens of markets, a shared evaluation framework reduces the need to build custom assessment processes for each provider. For broadcasters negotiating multi-year measurement contracts, the framework provides a documented standard they can reference when evaluating capability claims.

The Buyer's Guide is specifically structured for use as an RFI checklist or vendor scorecard. For each question, the guide recommends asking providers to show methodology, current capability, any known limitation, and the roadmap for capabilities that are not yet fully mature. Documentation, examples, and sample outputs are to be requested rather than verbal assurances.

Local TV advertising remains a significant component of U.S. ad spending, even as digital and streaming channels draw an increasing share of budgets. The structure of the local marketplace - geographically defined markets, station-level negotiations, and transactions that depend on market-level audience data - creates requirements that national or digital measurement frameworks do not automatically satisfy. The CIMM and TVB guidelines, released today, represent the industry's attempt to make those requirements explicit and to give both buyers and sellers a common language for evaluating whether any given measurement solution actually meets them.
