Inscape and Locality Partner to Provide Unified Linear and Streaming Ad Measurement for National and Local Markets

The landscape of television advertising is undergoing a fundamental transformation as audience behavior shifts rapidly from traditional broadcast signals to fragmented streaming environments. In response to this industry-wide shift, data and measurement firm Inscape, a subsidiary of Vizio, and local video advertising provider Locality have announced a strategic partnership aimed at bridging the measurement gap between linear and connected TV (CTV) inventory. This collaboration seeks to provide marketers with a unified view of advertising performance, enabling them to calculate incremental reach, frequency, and audience engagement across both local and national footprints.

The partnership comes at a critical juncture for the $87 billion television advertising industry, which has struggled for years to reconcile the precise, digital-first metrics of streaming with the long-standing, panel-based methodologies of linear television. By integrating Inscape’s robust, census-level glass-level data with Locality’s premium local video inventory, the two companies aim to solve one of the most persistent challenges in modern media buying: the inability to track ad exposure accurately across different delivery systems.

The Fragmentation Problem in Modern Media

To understand the significance of this collaboration, one must first look at the current state of television viewership. According to recent data from Nielsen and various industry trackers, the share of time spent with streaming services has surpassed traditional broadcast and cable television among key demographics. However, while streaming platforms offer granular data regarding user behavior, linear TV measurement has historically relied on representative panels. This dichotomy often leaves advertisers with "blind spots" when trying to measure a campaign that runs simultaneously on a local news broadcast and a streaming application.

Advertisers frequently face the risk of "over-frequency," where the same consumer is bombarded with the same advertisement across multiple devices, leading to wasted spend and viewer fatigue. Alternatively, they struggle to capture "incremental reach"—the new households they might reach via CTV that were not exposed to the linear campaign. The partnership between Inscape and Locality is specifically designed to eliminate these inefficiencies by providing a single, coherent data set that maps viewership habits across devices.

Chronology of Industry Shifts

The move toward unified measurement has been a long time coming. The timeline of this transition can be traced back to the early 2010s, when the rise of SVOD (subscription video on demand) began to erode the dominance of traditional cable bundles. By 2018, the industry saw a surge in the acquisition of data firms by hardware manufacturers, most notably Vizio’s strategic push into the data business through Inscape.

In the subsequent years, the industry moved from "approximate" measurement to "identity-based" measurement. Locality, which was formed through the merger of CoxReps and Gamut, has spent the last few years positioning itself as the premier partner for local video, recognizing that local broadcast remains a potent, yet under-measured, medium for advertisers. The integration announced this week represents the culmination of this trend, as the market shifts from "TV vs. Streaming" to a holistic "Total Video" investment strategy.

Leveraging Inscape’s Glass-Level Data

The core value proposition of this partnership rests on the nature of Inscape’s data. Unlike panel-based models, Inscape utilizes "glass-level" data—automatic content recognition (ACR) technology embedded directly into millions of smart televisions. This allows for a census-style view of what is on the screen, regardless of whether the source is an over-the-air antenna, a cable box, or a streaming app.

By feeding this data into Locality’s planning tools, advertisers can now see a unified picture. For example, a brand running a campaign for a new automotive model in a specific local market can now identify which percentage of their target audience viewed the ad on a local news station and which percentage viewed it on a streaming platform, such as a FAST (free ad-supported streaming TV) channel. This allows for dynamic budget reallocation, where funds can be shifted in real-time toward the medium that is currently driving higher incremental reach.

Official Perspectives on the Integration

The collaboration has been framed by both parties as a necessary evolution for the advertising ecosystem. Keith Kazerman, President of Streaming at Locality, emphasized that the partnership provides the company with a distinct competitive advantage.

"Combining our access to premium local video at unduplicated scale with Inscape’s comprehensive local-level viewership data uniquely positions Locality to understand how ad campaigns perform across both linear and streaming distribution," Kazerman stated. He noted that the primary goal is to empower partners to demonstrate their unique reach, effectively proving the value of local broadcast inventory in a way that aligns with the digital-native expectations of modern marketing teams.

Ken Norcross, VP of Data Licensing and Strategy at Vizio/Inscape, echoed these sentiments, framing the solution as an essential tool for fiscal responsibility. "The solution this partnership brings to the $87 billion ad industry is access to unified data across locally targeted linear and streaming, driving operational and budgetary efficiencies," Norcross said. He highlighted the importance of a single-source approach, noting that by focusing on content, commercials, and viewing behaviors cohesively, the partnership creates a more seamless experience for advertisers who have grown tired of stitching together disparate reports from different media vendors.

Market Implications and Future Outlook

The implications of this partnership extend beyond simple reporting. In the long term, this data integration will likely facilitate more advanced programmatic buying for local linear TV. As the barrier between "linear" and "digital" continues to blur, the ability to apply digital-style attribution to traditional broadcast slots will become the standard.

For the local media industry, which has seen its share of advertising dollars shift toward major tech platforms (such as Google and Meta), this is a critical defense mechanism. By providing advertisers with the same level of transparency and data sophistication that they receive from digital giants, local broadcasters and streaming services can better justify their premium rates and demonstrate the efficacy of their inventory in driving actual business outcomes, such as store visits or website conversions.

Furthermore, this move may pressure other players in the measurement space to accelerate their own integrations. As advertisers demand more transparency and consolidation, the "walled garden" approach to measurement is becoming increasingly untenable. Companies that fail to provide cross-platform, unified views of the consumer journey may find themselves sidelined as brands prioritize partners who can prove the ROI of their omni-channel campaigns.

Conclusion: A Data-Driven Future

As the television industry moves further into the streaming-first era, the technical ability to measure viewership is becoming as important as the content itself. The partnership between Inscape and Locality is a clear signal that the era of siloed measurement is coming to an end. By integrating local linear broadcast data with streaming insights, the companies are not just providing a service; they are helping to define the new infrastructure of the television advertising economy.

For the average marketer, the result will be more precise targeting, reduced waste, and a clearer understanding of how their dollars are performing across the increasingly complex mosaic of modern television. As these tools become more widely adopted, the industry will likely see a shift toward more automated, data-driven buying cycles that reflect the true value of video content, regardless of the screen on which it is delivered. The success of this initiative will hinge on the continued accuracy of the data and the ease with which agencies can incorporate these new insights into their existing workflow, but the foundation laid by this partnership marks a significant milestone in the ongoing digital transformation of television.
