LG Ad Solutions has partnered with Best Buy Ads to make inventory across the LG Electronics TV ecosystem available to U.S. retail media advertisers, including LG’s Home Screen and CTV video inventory. The deal marks the first time LG says its Home Screen inventory has been offered through a retail media network.
The partnership reflects the convergence of retail media and connected TV, as advertisers look to extend retailer first-party audiences into premium video environments while retaining measurement tied to commercial outcomes.
Under the arrangement, consumer electronics brands using Best Buy Ads can activate Best Buy’s first-party shopper audiences across LG’s TV ecosystem. The inventory is transacted programmatically through Magnite, while Best Buy’s closed-loop measurement connects campaign exposure with sales outcomes.
Retail Media Moves Onto the TV Home Screen
LG’s Home Screen represents a distinct advertising environment because it sits before consumers begin watching content. Making that inventory available through Best Buy Ads effectively introduces retail media demand into a CTV environment beyond the retailer’s owned properties.
For consumer electronics advertisers, the arrangement creates an opportunity to use retailer audience data while reaching consumers during the discovery stage of the purchase journey.
The broader significance is the separation of audience ownership from media ownership. Best Buy contributes its first-party shopper audiences and measurement capabilities, while LG provides the television inventory. Magnite supplies the programmatic transaction layer connecting the two sides.
Programmatic CTV and Measurement
Programmatic buying is central to the partnership. The companies say inventory will transact through Magnite, enabling Best Buy Ads demand to access LG’s premium TV inventory through established programmatic infrastructure.
Measurement is another key component. Best Buy’s closed-loop measurement is designed to connect advertising exposure with sales outcomes, giving advertisers a mechanism to evaluate campaigns against downstream commerce activity.
LG says the partnership also extends its Own the Outcome measurement framework, introduced at the 2026 IAB NewFronts, by strengthening attribution within a retail media environment.
The combination illustrates how CTV is increasingly being positioned as an addressable component of broader commerce-oriented media strategies rather than solely as a video branding channel.
Impact on Advertisers and Agencies
For advertisers, the arrangement potentially reduces the separation between retail media and television buying. Brands already investing in Best Buy’s shopper audiences can extend those audiences into LG’s TV environment without abandoning the retailer’s measurement framework.
Agencies can also gain another route for incorporating CTV into retail media strategies, particularly for consumer electronics campaigns where purchase behavior and product consideration are closely connected.
The model’s effectiveness will ultimately depend on audience scale, inventory availability, targeting capabilities, campaign economics and the quality of sales attribution. The announcement does not disclose pricing, audience size or performance benchmarks.
Competitive and Ecosystem Context
The partnership highlights a broader shift in the CTV market toward audience-enabled, outcome-oriented inventory. Retail media networks bring valuable first-party commerce data, while TV manufacturers control increasingly important connected-TV environments.
For LG, bringing retail media demand onto the Home Screen diversifies the sources of advertising investment available to its TV ecosystem. For Best Buy, extending its audiences beyond retailer-owned properties expands the media environments in which its shopper data can be activated.
Programmatic infrastructure is critical to that model because it allows retailer demand and CTV supply to interact without requiring a direct transaction for every campaign.
Strategic Outlook
The LG-Best Buy arrangement points toward a retail media model increasingly connected to premium CTV supply. Rather than keeping retailer audiences within retailer properties, the partnership allows those audiences to be activated against external media inventory while maintaining a connection to sales measurement.
The Home Screen component is particularly significant because it expands retail media into a high-visibility TV interface that exists outside conventional streamed video.
As more CTV and retail media businesses converge, the competitive advantage will likely depend not simply on inventory scale but on the combination of first-party audiences, programmatic access and credible outcome measurement.
