Comscore this week announced agreements with more than 15 broadcast clients for its local measurement products, the latest sign that the Reston, Virginia-based measurement company is consolidating its position in a market where national advertisers increasingly require local data to plan campaigns across fragmented viewing environments.

The announcement, dated April 21, 2026, names a broad cross-section of station groups. According to the press release, clients who have renewed, extended, or initiated new relationships include Allen Media Group, Cowles Montana Media including KHQ-TV, Cox Media Group, Cunningham Broadcasting Corporation, Community Television Inc. (WATC), Dominion Broadcasting (WLMB), Hubbard Broadcasting, Rincon, Sinclair Broadcast Group, The E.W. Scripps Company, and Thomas Broadcasting. The combination of large-footprint operators like Sinclair and Cox alongside smaller independent stations such as WATC and WLMB points to demand that extends well beyond the top-tier station groups.

The strategic logic for broadcasters

Local television has been under sustained pressure from streaming. CTV's share of media budgets is on track to hit 43% of total U.S. TV ad spend in 2026, up from 23% in 2022, according to eMarketer projections tracked by PPC Land. Against that backdrop, broadcasters are searching for measurement that can demonstrate their value in cross-platform terms rather than defending the old linear-only model. The Comscore announcements reflect that strategic pressure.

Sinclair, which operates one of the largest local television networks in the United States, has been navigating this shift for several years. According to Rob Weisbord, Chief Operating Officer and President of Local Media at Sinclair, "Sinclair has evolved into a cross-platform media company, and we need measurement that fully reflects how and where we're delivering our audiences. Local is a critical component of national advertising strategies, and advertisers deserve measurement that is accurate, accountable, and keeps pace with today's cross-platform viewing behavior, which is essential to accurately valuing our inventory and delivering meaningful outcomes."

The statement from Weisbord captures a tension that runs through the entire local broadcasting sector. Inventory valuation depends directly on the quality and credibility of the measurement underpinning it. If a broadcaster cannot show how its audiences behave across linear, streaming, and digital simultaneously, it is at a structural disadvantage when negotiating with national advertisers who have access to granular attribution data from digital channels. That dynamic has intensified as CTV measurement infrastructure has advanced significantly, raising expectations across the board.

What Comscore is offering

According to Comscore, its local measurement capabilities include cross-platform measurement and digital syndicated solutions that allow brands and agencies to plan and evaluate local performance with greater consistency. The company describes the products as enabling "more consistent cross-market decisioning," a phrase that points to one of the structural challenges in local TV advertising: campaigns running across dozens of markets have historically faced fragmented data, making it difficult to draw unified conclusions.

Comscore has been building toward this position for several years. In February 2024, the company expanded its Comscore Campaign Ratings product to cover the top 100 local U.S. markets, introducing deduplicated audience measurement across programmatic environments, digital platforms, streaming, and social channels. That product, known as CCR Local, was the first time the company brought cross-platform measurement to the hyper-local level with full coverage of the top 100 Designated Market Areas. The Trade Desk was the first demand-side platform to integrate CCR Local, giving its clients access to market-specific insights.

In March 2024, Comscore achieved MRC accreditation for national and local TV measurement, becoming at that point the only accredited local TV measurement company using big data methodology. That accreditation was later expanded. In April 2025, Comscore secured MRC accreditation for demographic TV metrics - specifically the "households with" age and gender breaks - across all 210 measured local markets. The company then completed its Joint Industry Committee certification for national TV measurement in July 2025, becoming the only provider with full JIC certification across all measurement categories.

These accreditations matter for the commercial relationships being announced today. Multi-year broadcast contracts are not signed lightly. Stations committing to a measurement provider over several years need confidence that the underlying methodology will hold up to scrutiny from national advertisers and agency holding groups. Independent certification from both the MRC and the JIC provides that assurance in a way that self-attested measurement cannot.

According to the April 21 announcement, Comscore identifies four distinct trends shaping the local market: continued adoption by new broadcasters, expanded market coverage, growth in multi-year contracts, and increasing adoption of cross-platform reporting by local broadcasters as they grow audiences across digital, streaming, and social.

The multi-year contract trend is particularly significant. Longer commitments reduce churn risk for Comscore and indicate that clients see measurement as infrastructure rather than a discretionary cost. In a market where Nielsen controls 85% to 90% of national TV measurement revenue - estimated at $1.5 billion to $2 billion annually according to a January 2026 study commissioned by the Coalition for Innovative Media Measurement - Comscore and VideoAmp split the remainder. That competitive position gives Comscore an incentive to lock in broadcasters on extended agreements before the market restructures further.

Tara Gotch, EVP Commercial at Comscore, framed the momentum in terms of accelerating adoption. According to Gotch, "Local is a must-have for national advertisers seeking both scale and impact. As the industry evolves, we're seeing accelerating adoption from local broadcasters who want modern measurement that reflects how audiences actually consume content today, across screens and platforms. Our expansion into more markets and the increase in multi-year agreements signal that local measurement is becoming a strategic foundation for national investment."

The phrase "strategic foundation" is deliberate. For years, local measurement was treated as a supplementary layer on top of national campaign planning. The argument embedded in today's announcement is that this relationship is inverting - that local audience intelligence is becoming the starting point for national media investment decisions, not an afterthought.

The technical infrastructure behind the claim

Comscore's pitch to local broadcasters rests on a technical architecture that has evolved substantially. The core of the local measurement offering tracks viewing behavior across all 210 U.S. Designated Market Areas using big data methodology rather than traditional panel-only approaches. Unlike panel-based systems that project from a small sample, big data measurement ingests device-level signals from millions of households, applying statistical models to correct for known biases in the underlying data sources.

In January 2025, Comscore launched cross-platform content analysis tools for media companies through its unified Content Measurement system, integrating multiple data streams to analyze audience behavior across linear television, streaming services, personal computers, mobile devices, and social platforms. That system was enhanced in January 2026 with program-level reporting powered by Amazon Bedrock agentic AI technology, enabling daily updates on audience engagement down to the episode level - a capability relevant to local broadcasters that carry syndicated programming alongside local news.

The person-level measurement work has also progressed. In June 2025, Comscore integrated person-level viewing data into ShowSeeker's Pilot platform, introducing demographic insights that extend beyond traditional household-level metrics for local television campaigns. That granularity - age, gender, and viewing behavior at the individual level within local markets - provides the raw material for the kind of targeted planning that national advertisers require.

For connected television specifically, the July 2025 partnership with HyphaMetrics introduced CTV program-level reporting and person-level audience measurement through HyphaMetrics' proprietary Unified Individual Media Metric. That partnership was explicitly timed ahead of the 2026/2027 upfront season, the period when broadcasters and streaming services negotiate advertising commitments with agencies.

Why this matters for national advertisers

National advertisers have not retreated from local media. The press release notes that national brands continue to depend on local media alongside local advertisers to reach audiences with "scale, relevance, and community connection." That observation reflects a well-documented reality: a significant share of consumer goods purchasing occurs at the local level, meaning national brands need local data to understand whether their campaigns are working in specific geographies.

The Comscore and Yahoo DSP political advertising partnership announced in March 2026 illustrated one concrete application of this local-national measurement bridge. That deal fed Comscore's verified linear TV exposure data from all 210 Designated Market Areas into CTV targeting for political campaigns, allowing advertisers to identify voters not yet reached by their linear spend and extend reach incrementally through connected television. The same infrastructure is applicable to commercial advertising, where local market optimization can improve the efficiency of national buys.

The Proximic by Comscore division adds a targeting layer on top of the measurement infrastructure. In January 2026, Comscore announced audio targeting and measurement capabilities on The Trade Desk platform, combining AI-powered contextual targeting across 4.6 million podcasts with national and local reach and frequency measurement. That capability demonstrates how Comscore's local measurement methodology extends beyond television into adjacent channels that local broadcasters are increasingly operating across.

The competitive context

Today's announcement arrives at a moment of heightened tension in TV measurement. Nielsen remains the dominant provider but is facing pressure. Meta announced in March 2026 that it would replace Nielsen's Designated Market Area targeting with Comscore Markets for automotive model ads by June 2026. That decision - moving from Nielsen's geographic framework to Comscore's - represents a commercial signal that Comscore's local market infrastructure is gaining traction in places beyond traditional broadcast.

The measurement market itself is under scrutiny. A January 2026 study found that switching costs between measurement providers are enormous, involving trend breaks, operational disruption, and contractual complexity. That structural stickiness makes today's new client announcements more valuable than they might appear on the surface. Each new multi-year agreement represents not only immediate revenue but a long-term commitment that is difficult to reverse.

The Nielsen Gauge measurement dispute that emerged publicly in late March 2026, in which broadcasters accused Nielsen of suppressing viewership data favorable to linear television, has added urgency to the industry's search for credible third-party alternatives. Comscore, as the only measurement provider with both full JIC certification and MRC accreditation across all 210 local markets, occupies a distinctive position in that context.

The company has also expanded into areas beyond traditional television. Comscore's Scoreboard report from February 2026, cited by the Video Advertising Bureau's annual streaming report, tracked streaming's share of national ad time rising from 16% in September 2025 to 18% in December 2025, while broadcast held 47% and cable fell from 39% to 35% over the same period. That data gives Comscore credibility with both the broadcast clients signing today's agreements and the streaming buyers who are gaining share.

What the station names reveal

The specific station groups named in the announcement span different scales and ownership structures. Sinclair Broadcast Group is one of the largest television broadcasting companies in the United States by station count. The E.W. Scripps Company and Cox Media Group operate regional station portfolios with significant reach in major markets. Allen Media Group has expanded aggressively in recent years, acquiring stations across multiple markets. Hubbard Broadcasting operates a mix of network affiliates and independent stations.

At the other end of the spectrum, Community Television Inc. (WATC) and Dominion Broadcasting (WLMB) represent smaller, independent operations. Their inclusion alongside the major groups is notable because it indicates that the demand for cross-platform local measurement is not confined to well-resourced operators with sophisticated research departments. Smaller stations appear to be reaching the same conclusion about measurement as a competitive necessity.

Cowles Montana Media, which includes KHQ-TV based in Spokane, represents a regional operator serving markets that receive less attention in national measurement conversations. The inclusion of Montana-based operations points to Comscore's stated goal of expanding local coverage beyond the largest Designated Market Areas, enabling "broader, more consistent market-level reporting for national and regional buying" according to the announcement.
