Retail media networks are booming—but they’re also hitting real constraints around scale, signal loss, and measurement.
In this episode of Retail Media Unboxed, we sit down with Colin Grieves, Managing Director at Experian Marketing Services UK and Ireland, to unpack what’s actually changing beneath the surface of retail media in 2026.
We explore why first-party data alone is no longer enough, how privacy-safe third-party insight helps resolve the precision-vs-scale trade-off, and why interoperability and collaboration are becoming essential for retailers, agencies, and brands alike. The conversation also dives into shifting consumer behavior, value-seeking mindsets, and the critical role high-quality data will play as AI becomes embedded across media buying, creative, and measurement.
