Comscore's Local TV Deals Signal Major Shift in Ad Measurement

RESTON, VA – April 21, 2026 – Measurement firm Comscore has announced a wave of new and renewed agreements with more than 15 local broadcast groups, a move that signals a deeper industry-wide shift in how television audiences are measured and valued. The deals, which include major players like Sinclair Broadcast Group, Cox Media Group, and The E.W. Scripps Company, underscore a growing demand for a more modern, cross-platform currency that can accurately capture viewership across linear TV, streaming, and digital channels.

The End of Siloed Measurement

The announcement arrives as the media landscape grapples with unprecedented audience fragmentation. For decades, advertising decisions were based on relatively straightforward linear television ratings. Today, viewers consume content across a dizzying array of platforms—from traditional broadcast and cable to Connected TV (CTV) apps, FAST channels, and mobile streams. This fragmentation has created significant challenges for advertisers and broadcasters alike.

Industry studies have highlighted critical gaps in legacy measurement systems, with some estimates suggesting that as much as 20% to 30% of local viewing goes uncredited. This "ghost viewership," primarily occurring on digital platforms, represents billions of lost impressions and a distorted picture of a broadcaster's true reach. National advertisers, who rely on local media to connect with communities at scale, are increasingly demanding a unified view of their campaign performance.

"Local is a must-have for national advertisers seeking both scale and impact," said Tara Gotch, EVP Commercial at Comscore, in the company's announcement. "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." Comscore's approach aims to bridge this gap by integrating data from set-top boxes, smart TVs, and digital panels to create a single, deduplicated picture of household viewership.

A Lifeline for Local Broadcasters

For local station groups, the stakes could not be higher. As digital advertising continues to capture a larger share of marketing budgets—with BIA Advisory Services projecting digital's share of local ad spend to surpass 50% for the first time—broadcasters face immense pressure to prove their value beyond the traditional 30-second spot. Adopting comprehensive, cross-platform measurement is becoming less of a choice and more of a strategic imperative for survival and growth.

These new measurement tools allow local stations to more accurately value their inventory. By demonstrating their full audience reach across all platforms, they can better compete with digital-native publishers for advertising dollars. The ability to provide granular insights, down to the zip code level, empowers their sales teams to offer advertisers more targeted and effective solutions.

This sentiment was echoed by Rob Weisbord, Chief Operating Officer 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," Weisbord stated. "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 increase in multi-year agreements with firms like Comscore suggests broadcasters are seeking long-term, stable partnerships to navigate this complex transition.

A Multi-Currency Marketplace Emerges

Comscore's momentum is also a reflection of a changing competitive dynamic in the measurement industry. For years, Nielsen has been the dominant currency for television advertising. However, the company has faced scrutiny and challenges in adapting to the multi-screen era, including questions from the Media Rating Council (MRC) about the validity of its panels. This has created an opening for alternative measurement providers.

The market is rapidly evolving from a single-currency monopoly to a multi-currency ecosystem. Large media companies are no longer beholden to a single provider. Instead, they are strategically leveraging multiple partners to gain the most comprehensive understanding of their audiences. For example, Allen Media Group, one of the clients named in Comscore's announcement, has also struck significant deals with competitors like VideoAmp, signaling a clear strategy to diversify its measurement portfolio.

This competitive pressure is forcing all players to innovate. Comscore has differentiated itself with its large-scale data footprint, which combines viewership intelligence from millions of households. While it faces competition from Nielsen's own cross-platform initiatives and other emerging players like iSpot.tv, its recent string of local agreements solidifies its position as a major contender in the race to define the future of media currency.

From Local Insights to National Strategy

Ultimately, the trend toward more sophisticated local measurement is driven by the needs of advertisers. National brands are learning that effective campaigns require more than just broad reach; they need local relevance. Understanding how consumer behavior and media consumption differ from market to market is key to connecting with audiences and driving business results.

By providing a more consistent and transparent reporting framework across different markets, solutions like Comscore's enable national media buyers to plan and evaluate local performance with greater clarity. This allows for more confident investment decisions and a better understanding of campaign return on investment (ROI). The data helps brands activate audiences where they live and shop, bridging the gap between national strategy and local execution.

The expansion of these measurement capabilities into more local markets and the increasing adoption of cross-platform reporting are not just technical upgrades; they represent a fundamental rethinking of how media is bought, sold, and evaluated. As the lines between digital and linear television continue to blur, the ability to follow the audience across every screen will be the defining factor for success in the next era of advertising.
