Episode Details

Retail media technology has already gone through several major reinventions. From retailers building their own ad tech stacks, to point solutions, cloud-based composable technology, and now AI-ready data infrastructure.

In this episode, I’m recapping my recent article for The Drum, and exploring the four eras of retail media tech. More importantly, why these eras aren’t necessarily sequential. Across retail media networks today, you can find very different technology architectures operating at the same time, and I dig into what led up to this moment. 

Tomorrow, in part two, I’ll look at another framework for thinking about retail media technology investment and what all of this means for the brands actually buying retail media.
