by Experian Marketing Services 3 min read August 5, 2026

See shopper activity across retailers

Retail media gives one view of the customer. However, to scale, commerce media knows they need to have a holistic view of the customer. At Cannes Lions 2026, leaders from Above Data, Adobe DSP, Fetch, FreeWheel, Genius Sports, Grupo Bimbo, Navigator, PayPal, and PMG explored what this shift means for measurement, access to data and inventory, shoppable media, and long-term brand building. Watch the conversation below to hear how they define commerce media, what brands still get wrong, and where the space is headed.

From proxies to incremental purchases

Why deterministic transaction signals can provide a stronger anchor for measuring real-world outcomes.

Walled gardens or open doors

How concentrated access can limit participation—and how federated models may expand access for smaller brands.

The say-do gap

Why more media is becoming shoppable, and why immediate incrementality still needs to be balanced with long-term brand building.
