Retail media networks: turning your screens into ad inventory

Key Takeaways

• Retail media, advertising placed at or near the point of purchase, made up roughly 21% of global digital advertising spend as of 2024, and has grown from a niche category into a mainstream media line item that brands budget for directly.
• A meaningful share of retail media revenue now runs "off-site" too, retailers licensing their first-party shopper data to reach the same audience on other channels, not just on their own screens, which broadens what a retail media business can sell beyond the physical screen itself.
• The value retailers are actually selling is measurable audience data and purchase-intent proximity, not just screen space, which is why third-party cookie deprecation has made retailer-owned, first-party audience data increasingly valuable to advertisers.
• Many successful retail media operations run through specialist media companies rather than being managed directly by the retailer, partly to keep the audience-measurement and sales function credible and separate from the retailer's own merchandising interests.

A business that already has screens installed in-store, for menus, wayfinding, or promotions, is sitting on a media asset whether it's monetised or not. Retail media has moved from an experimental add-on to a mainstream ad category with real budget behind it, but turning existing screens into genuine ad inventory requires more than just accepting a sponsor's file to play.

Why this category grew from niche to roughly a fifth of digital ad spend

Retail media, marketing to consumers at or near their point of purchase or point of choice between competing products, represented approximately 21% of global digital advertising spending as of 2024 (Wikipedia, retail media, retrieved 2026-09-10). That's not a rounding-error category, it's a meaningful share of where digital ad budgets actually go, and it reflects a structural shift: brands are paying to reach shoppers at the moment of decision, with a retailer's first-party data backing up who actually saw and responded to the ad, rather than paying for broad-reach impressions with weaker attribution.

Why third-party cookie deprecation made this more valuable, not less

As third-party tracking cookies have been phased out across the web, first-party data collected directly by retailers, who a shopper actually is, what they buy, when they're in-store, has become a more valuable targeting asset rather than a less valuable one (Wikipedia, retail media, retrieved 2026-09-10). A retailer or venue operator with screens and a genuine, measurable audience is now selling something advertisers increasingly can't replicate through other channels, real proximity to a purchase decision, backed by data the retailer itself controls.

On-site vs off-site: the inventory is bigger than just the screens

Retail media splits into on-site (ad placements on the retailer's own property, including physical screens and website placements near purchase points) and off-site (licensing the retailer's audience data to reach the same shoppers on other channels across the web) (Wikipedia, retail media, retrieved 2026-09-10). A business building a retail media offering around its physical screens shouldn't treat the screens as the entire product, the audience data behind those screens has value that extends beyond the physical inventory itself, and is worth structuring as a separate, sellable asset.

Why credible measurement matters more than screen count

The advantage retail media networks offer over generic outdoor advertising is accountability: audience measurement techniques comparable to traditional broadcast or print media, not just "we have screens in busy locations" (Wikipedia, retail media, retrieved 2026-09-10). This is also why many retail media operations run through specialist media companies rather than being sold directly by store or venue staff, keeping the measurement and sales function credible and at arm's length from the retailer's own merchandising interests is part of what makes a brand willing to pay a premium rather than treating the screens as an afterthought ad placement. Before pricing ad inventory, model the actual audience reach and expected advertiser lifetime value through the CAC/LTV calculator, since credible measurement is what determines whether a brand renews the placement or treats it as a one-off test.

What this means for a business with existing screens

The screens themselves are necessary but not sufficient. What actually sells to a brand is a measurable, credible audience with genuine purchase-intent proximity, evidenced by real data, not a sales pitch. A business converting existing digital signage into ad inventory needs to invest in the measurement and reporting layer at least as much as in selling the ad slots themselves, since that's what determines whether the first sale becomes a renewed, growing relationship.

For a business weighing whether to expand its screen footprint specifically to build this kind of ad inventory, working through the numbers with an LED business planning tool helps separate the signage investment case from the media-sales case before committing capital to more screens.

Frequently asked questions

Is retail media just outdoor advertising with extra steps?

No, the key differentiator is measurable, first-party audience data tied to actual purchase behaviour, which traditional outdoor advertising generally can't offer. That data-backed accountability is what lets retail media command premium pricing versus generic ad space.

Does retail media only work for large retailers with heavy foot traffic?

Scale helps, but the core requirement is a genuine, measurable audience with purchase-intent proximity, not necessarily massive volume. A smaller, well-measured, clearly-defined audience can still be commercially attractive to the right advertiser if the data behind it is credible.

Why do retailers often use a separate media company rather than selling ad space themselves?

Partly for credibility (arm's-length measurement looks more trustworthy to advertisers than self-reported numbers from the retailer), and partly because building and operating an ad sales function is a different skill set from retail operations, one that a specialist company is often better positioned to run well.

The bottom line

Existing in-store or venue screens are a real, sellable media asset, and retail media has grown into a category brands genuinely budget for, not a novelty. But the product a brand is actually paying for is measurable, credible audience data, not screen space by itself, which means the investment worth making first is in measurement and reporting, not just in filling airtime with a sponsor's content.
