Retail media consolidation and incrementality scrutiny predicted
At the Advertising Club of New York's Commerce Media Exchange, Jason Colon of Horizon Commerce argued that the retail media landscape is facing a period of consolidation due to fragmentation and increased scrutiny from advertisers. He stated that the 'golden era of attribution' is over and that advertisers now demand proof of incrementality. Colon believes that not every retailer needs its own media network, and that many smaller networks lack differentiation. He predicts a 'forced consolidation' in the sector and emphasizes that commerce media should be integrated into holistic media strategies rather than being siloed. He also suggests that the distinction between retail media and general media will eventually disappear as data-driven commerce capabilities become standard practice.
