Why CMOs Are Redistricting Media Budgets by Zip Code

Episode notes

Episode 52 of The CMO Podcast digs into a surprising trend reshaping marketing budgets in 2026: hyperlocal zip-code targeting. Lucas breaks down how CMOs at national brands like Target and Home Depot are shifting away from broad DMA buys toward granular neighborhood-level allocation, using first-party purchase data and AI-driven geomapping. Luna challenges the approach on privacy grounds, and they examine the trade-off between relevance and scale. Specific example: how a midwestern grocery chain increased ROI by 22% after reallocating 15% of its TV budget to programmatic ads served only within a three-mile radius of its stores. The conversation touches on the rise of 'addressable geofencing,' the risk of creating marketing deserts in low-income areas, and why this might be the most significant media-buying shift since programmatic itself. By the end, listeners will understand the mechanics, the ethics, and the metrics behind the new zip-code playbook.
