Grocery TV today announced a partnership with ABCS Insights that brings independent, third-party sales lift measurement to in-store retail media. The New York City announcement marks one of the more technically specific additions to in-store measurement infrastructure in the current cycle - giving brands advertising on Grocery TV's network a way to connect ad exposure inside a store directly to verified purchases at the product level, whether those purchases happen in-store or at other retailers entirely.

The move comes as the broader retail media industry confronts a persistent measurement credibility gap. Brands have long been able to measure online retail media with reasonable confidence, but physical stores have resisted the same level of accountability. That gap is now narrowing, and the Grocery TV and ABCS announcement is one data point in a wider industry movement toward causal, purchase-based verification of in-store advertising.

What ABCS Insights brings to the partnership

The core of the deal is access to ABCS Insights' panel, which covers 41 million households across the United States. The panel combines two data types: receipt data and card transaction data. Together, those streams allow ABCS to construct a picture of purchase behavior that spans multiple retailers, not just the one where the ad appeared.

According to the announcement, the receipt-based measurement methodology captures what ABCS calls the full halo effect of a campaign - meaning it tracks sales lift at every retailer where panellists shop, not only at the store where the in-store screen was located. This matters for CPG brands, whose products are typically sold across dozens of retail chains simultaneously. A candy campaign running in one grocery chain may influence purchases at a competing chain later that week; receipt-based measurement can detect that signal, whereas a closed-loop system tied to a single retailer's point-of-sale data cannot.

All campaign measurements are conducted at the product level. According to the companies, the environment is privacy-safe and applies the same measurement capabilities that brands expect from digital channels, now extended to a physical retail setting.

Early campaign results

Two early campaigns from CPG brands illustrate the claimed performance. A national candy brand ran a two-month campaign on Grocery TV's network supporting a seasonal product launch. According to the announcement, that campaign delivered an incremental return on ad spend (iROAS) of 11.7x and drove $2.7 million in incremental sales.

A leading beverage brand produced a different profile: 5x iROAS, $1.4 million in incremental sales, a 5% increase in purchase frequency, and a 16% sales lift driven by on-platform ad exposure. The two results differ considerably in their iROAS figures, reflecting both category differences and distinct measurement conditions across each campaign.

The use of iROAS rather than total ROAS is a deliberate technical choice. iROAS measures only the sales that would not have occurred without the advertising - additional demand created by the campaign rather than purchases that would have happened regardless. As PPC Land reported in April 2026, the iROAS framework distinguishes additional sales caused by advertising from baseline sales, a distinction that carries commercial weight when every media dollar requires justification.

Where this fits in Grocery TV's existing measurement stack

The ABCS partnership does not replace Grocery TV's existing measurement capabilities. According to the announcement, it extends them. Grocery TV had already assembled what it describes as a full-funnel measurement suite, which includes foot traffic measurement, brand lift, and consideration intent tracking.

In 2025, the company introduced a closed-loop solution using retailer point-of-sale data, beginning with Hy-Vee, to directly tie media exposure to sales. That system is first-party and retailer-specific: it uses POS data from the store where the ad ran. The ABCS partnership adds a third-party, panel-based layer that operates independently of any single retailer's data and extends coverage across the entire shopper journey, regardless of where a final purchase occurs.

The distinction between these two systems is technically meaningful. A closed-loop POS solution gives precise in-store conversion data but only within a specific retailer's footprint. A panel-based approach sacrifices some granularity but gains cross-retailer visibility and independent verification. Brands can now use both approaches in combination.

Voices from the announcement

Marlow Nickell, Co-founder and CEO of Grocery TV, addressed the strategic rationale directly. According to the press release, Nickell said: "In-store media delivers measurable results across the full shopper journey, and our measurement approach reflects that. ABCS adds an important layer of rigor for sales lift, so brands can see the incremental impact of their campaigns with independent verification."

Jerome Shimizu, CEO of ABCS Insights, pointed to the historical underdevelopment of in-store measurement. According to the announcement, Shimizu said: "In-store is at a critical moment in the path to purchase, yet it's historically been under-measured. This partnership with Grocery TV brings true purchase-based measurement to the channel, grounded in observed transaction data, so brands can understand exactly what outcomes their media investments are driving."

Grocery TV's network scale

Grocery TV describes itself as the leading in-store retail media platform. According to the company, more than 120 retailers partner with the platform to deploy digital screens inside stores. The network reaches over 6,500 locations, which the company says amounts to 1 in 4 Americans. Grocery TV frames its value proposition around the fact that, according to its own figures, 90% of purchases still occur in physical stores.

The industry context: measurement alignment has become a pressure point

The Grocery TV and ABCS announcement arrives during a period of unusual activity around in-store measurement standards. On April 7, 2026 - nine days before this announcement - In-Store Marketplace and Catalyst Media Consulting released a report arguing that the biggest obstacle to scaling digital in-store advertising is not a lack of technical measurement capability, but a fundamental misalignment between the scorecards used by brands, agencies, merchants, and retail media networks. That report identified four distinct scoring systems operating simultaneously across the ecosystem, creating gridlock when stakeholders attempted to agree on whether a campaign had succeeded.

The Grocery TV and ABCS partnership is one practical response to that diagnostic. By anchoring results in observed transaction data from an independent panel, it removes the retailer's POS system from the role of sole arbiter of performance. Independent third-party data occupies a different standing in advertiser budget conversations than self-reported network metrics.

Also on April 7, 2026, the IAB published a white paper arguing that Marketing Mix Modeling is structurally ill-suited for retail media and causes CPG brands to systematically undervalue the channel. That paper, co-authored by Collin Colburn of the IAB and Priyash Shahane of Instacart, urged brands to adopt closed-loop and incremental measurement instead. The Grocery TV and ABCS methodology is broadly aligned with that recommendation.

Further upstream, the IAB and IAB Europe published their Guidelines for Incremental Measurement in Commerce Media on November 3, 2025. That framework, which PPC Land covered at release, defined incrementality as the causal impact of marketing by identifying the additional business outcomes directly driven by a campaign, compared to what would have occurred without the activity. ABCS's iROAS figures for Grocery TV's early campaigns are expressed in exactly those terms.

The LiveRamp and Meta measurement integration announced in October 2025 extended similar logic to retail media networks wanting to verify Meta campaign performance against first-party sales data. The pattern across these announcements is consistent: the industry is moving from proxy metrics toward verified, transaction-level, independent measurement.

What ABCS Insights is

ABCS Insights describes itself as a measurement and analytics platform providing a unified view of how marketing and advertising drive real-world business outcomes. According to the company, its capabilities span independent, outcome-based measurement across channels, categories, and stages of the purchase journey. The platform draws on thousands of studies and large-scale, real-world purchase data. The 41 million household panel combining receipt and card transaction data is the core technical asset behind its sales lift measurement product.

Why this matters for the marketing community

In-store retail media has grown rapidly as a budget category, but the measurement infrastructure has consistently lagged behind digital channels. The pattern of brands working with multiple retail media networks simultaneously - documented by PPC Land across 2025 - has compounded the complexity, as each network has historically operated its own metrics framework. The Grocery TV and ABCS partnership is notable because it applies a single, independent panel-based methodology across the physical retail environment, offering a level of comparability that individual retailer POS systems cannot produce.

For CPG advertisers in particular, the product-level granularity matters. In-store campaigns often support specific SKUs or seasonal lines, and brand-level attribution obscures whether the right products actually moved. The ability to tie an in-store screen exposure to a specific product purchase - across any retailer where that product is sold - is a technically meaningful advance over category-level or brand-level reporting.

The question of what "incremental" means in practice is not fully settled across the industry. Different panel providers, different control group methodologies, and different measurement window definitions can produce substantially different iROAS figures from the same campaign. The Grocery TV announcement does not specify the exact methodology used to construct control groups for the candy and beverage campaigns, which will matter to sophisticated buyers evaluating those headline numbers against results from other platforms.

Still, the direction is clear. Third-party, panel-based, product-level, cross-retailer sales lift measurement is becoming an expected capability for serious in-store retail media networks. Grocery TV and ABCS Insights have made it available today.

Timeline

Summary

Who: Grocery TV, the in-store retail media platform operating across more than 6,500 US stores with 120-plus retail partners, and ABCS Insights, a measurement and analytics company with a 41-million-household panel combining receipt and card transaction data.

What: A partnership that makes independent, third-party sales lift measurement available to brands advertising on Grocery TV's in-store network. The capability connects in-store ad exposure to verified, product-level purchase outcomes across all retailers where a shopper buys - not just the store where the ad appeared. Early campaign results include 11.7x iROAS and $2.7 million in incremental sales for a candy brand over two months, and 5x iROAS, $1.4 million in incremental sales, and 16% sales lift for a beverage brand.

When: Announced April 16, 2026. The closed-loop POS integration with Hy-Vee, which this partnership extends, was introduced in 2025.

Where: The partnership applies to brands advertising on Grocery TV's US network. ABCS Insights' panel covers US households. The announcement was made from New York City.

Why: In-store retail media has historically lacked independent, purchase-verified measurement infrastructure comparable to digital channels. As brands work with multiple retail media networks and demand transparent, third-party evidence for budget allocation decisions, the absence of credible in-store measurement has constrained investment. The ABCS partnership introduces an independent panel-based layer that operates across retailers and provides product-level attribution, addressing a structural limitation the industry has been working to resolve throughout 2025 and into 2026.
