Commerce Media's Day Two: The Agentic Shelf and the Measurement Reckoning
About this episode
Retail media is now a $100 billion industry. Collin Colburn, VP of Commerce and Retail Media at the IAB, says we’ve entered commerce media's "day two" – the era where operational integration, interoperable measurement, and the arrival of the agentic shelf matter more than launching another network.
We unpack why brands started calling retail media a tax, why Collin says we should blow attribution up, and whether an ad-supported agent can stay trustworthy.
Welcome to Day Two
Key takeaways:
- Optimization and integration replace growth-at-all-costs expansion.
- Brands call retail media a “tax,” sensing the industry's referee is now incrementality.
- Agent-referred shoppers convert higher and return less.
- In-store media's ceiling is customer experience, not inventory: frequency caps beat non-endemic dollars.
- [14:05] "Agentic commerce isn't changing what consumers buy or want to buy today. It's changing their pathway to purchase." — Collin Colburn
- [19:35] “The coming reckoning is in the measurement space.” –– Collin Colburn
- [20:45] "Attribution was built for: an ad is served, it's clicked on or seen, the customer goes to the website, and they purchase. That model does not work well in this new era." — Collin Colburn
- [25:15] "AI feels objective to me for the most part… it's like your omnipotent friend that you never had. And when ads get introduced, it begs the question of, am I still gonna trust that agent?" — Collin Colburn
