Retail Media Breakfast Club

There’s a new beef in marketing, and this one hits close to home: can retail media actually build brands, or is it really just trade promotion with a fancy name and a dashboard? Mark Ritson kicked off the debate by arguing that retail media is fundamentally a bottom-of-funnel, defensive investment. Andrew Lipsman pushed back, making the case that retail media can do something brand marketers have wanted for decades: reach people who aren’t currently buying your brand.
In this episode, I dig into both sides of the argument, including the role of retailer data, off-site audiences, CTV, incrementality, ROAS and brand lift. I also look at some fresh Kantar data and ask a bigger question: are we actually debating what retail media is, or are we debating how marketers are choosing to spend their retail media budgets?

On August 27, Mark Ritson published a column in ADWEEK called "Don't Let Retail Media Tell You It's Brand Building."
Andrew Lipsman answered in his own ADWEEK op-ed five days later: "Retail Media Can Build Brands—Including Ways Other Media Can't."
Josh Clarkson, who runs global retail media at Mars, attacked Ritson's retail media definition on LinkedIn
Brian Spencer, marketing director at Kroger Precision Marketing, explained on LinkedIn that brands use retail media audiences across CTV, audio and social, not just onsite on a retailer's website.
Across 1,589 campaigns in their LIFT database, Kantar finds that retail media beats the average channel on unaided awareness (0.9 versus 0.6), online ad awareness (7.6 versus 6.5), brand favorability (3.9 versus 3.6) and purchase intent (3.8 versus 3.4)

Today, I’m digging into a question that has been coming up more and more as retail media expands into a broader commerce media ecosystem: does commerce media really need to be tied to the cart?
I’m narrating a guest contribution essay from Tom Limongello of The Middlemen Podcast that got me thinking differently about the distinction between retail media and commerce media. Specifically why SKUs and assortments are useful ways to understand retail media, but may not actually define it (and why the more important concept could be the shopper mission). Tom's essay also looks at travel media, where the network may own the audience and the moment of attention without owning the products ultimately purchased. And that raises some fascinating questions about measurement, attribution and who gets credit when multiple commerce media networks influence the same customer journey.

By now, you’ve probably read plenty of coverage about the FTC’s case against Amazon’s ad auction (last week I shared an article on The Drum). But the question I’m more interested in is the one that actually matters if you’re managing an advertising budget or running a retail media network: does any of this change where the money goes?

My prediction, sadly, is no. Though I’d be very happy to be proven wrong. 
In this episode, I break down why cheaper clicks probably wouldn’t mean less money for Amazon, why advertiser outrage may not translate into budget shifts, and why this case gives other retail media networks a short window to make transparency and auction mechanics a competitive advantage. I also dig into some fascinating arguments from the LinkedIn comments, including whether Amazon’s auction practices may have distorted industry benchmarks far beyond the individual advertisers involved.

[07:20] - How potentially inflated clearing prices could have contaminated retail media benchmarks and bidding tools
[09:35] - Why Amazon can disappoint advertisers morally and still be the best place to spend a performance dollar

Retail media has a fragmentation problem. We have better dashboards, better reporting, and better measurement than we did a few years ago. But media buyers are still being asked to navigate an ever-growing number of retail media networks and walled gardens.
In this episode, I look at what’s happening in the UK, where two major retail media aggregation plays launched over the summer: RMX by Plan-Apps from SMG and the dunnhumby network alliance, involving Tesco, B&Q, John Lewis and Waitrose. I also share snippets of a conversation from the Retail Media Therapy podcast with Co-op Media Network’s Dean Harris about why these platforms are emerging now, and why the real driver may have less to do with retailers wanting to collaborate and more to do with what advertisers and agencies increasingly expect.
But there’s a bigger question underneath all of this: what is retail media aggregation actually for? Is the value simply having one place to buy across multiple networks, or is it about being able to reach a particular audience in one place? And if competing retailers put their audiences into the same marketplace, do we risk turning retail media audiences into commodities and pushing CPMs down, just as programmatic advertising did to publisher audiences? That tension could determine whether retail media aggregation becomes a genuine solution to fragmentation or creates an entirely new set of problems for retailers.

After living outside Australia for around 15 years, I’m experiencing retail and shopping here with fresh eyes. And one thing that has really caught my attention is just how much retail media is showing up in the physical world.
In this first Trip Report, I’m taking you on a quick tour of six retail and commerce media activations I spotted around Perth. From Commonwealth Bank and Coles, to JB Hi-Fi, David Jones, Australia Post and digital out-of-home media in shopping centres. This isn’t about declaring one market “better” than another. Instead, I’m looking at what’s happening on the ground and using it as a source of inspiration for what’s possible in retail media around the world.

[06:15] - JB Hi-Fi’s transition from screens used for product demos to a more sophisticated, programmatic retail media network
[09:06] - David Jones’ Amplify network and the use of AI cameras to track views and dwell time
[10:00] - Australia Post turns parcel pickup infrastructure into an advertising opportunity, including a clever Vinted integration
[12:00] - The scale of digital out-of-home media inside Australian shopping centres and how local screens connect to a national network
