CMN (Commerce Media Network)
An advertising network run by a company with first-party shopper or transaction data, such as a retailer or marketplace, that sells ad space to brands; the term extends the retail media idea beyond the largest retailers.
Explanation
CMN widens the retail media network model beyond players like Amazon and Walmart to other retailers and marketplaces that hold direct shopper data. The term circulated among ad tech vendors from around 2023 and became common in marketer trade press in 2025-2026. Marketers now evaluate a wider set of CMN partners as first-party-data ad inventory, and financial platforms run a related variant, FMN.
Usage context / examples
A Forbes Agency Council article (April 2026), "Commerce Media Networks: The Next Frontier In Brand Advertising," describes CMNs as retailer and e-commerce platforms such as Amazon, Walmart, Target and Instacart that sell ads based on direct shopper data.
