Retail media networks expand beyond their own owned properties
Major retailers are extending their retail media networks beyond their own websites and apps into off-platform placements across social media, connected TV, and third-party publisher sites, using their proprietary purchase data to target audiences wherever they actually spend time online. This off-platform expansion meaningfully increases addressable inventory for retail media networks that were previously constrained to whatever traffic the retailer's own digital properties generated organically. Major retailers have announced partnerships with connected TV platforms and social networks specifically to extend first-party targeting capability into these off-platform environments. Analysts expect off-platform inventory to keep growing faster than owned-property placements this decade.
