Business Insider's CMO Insider coverage this week names the thing directly, "The $200 billion retail media boom is causing headaches for CMOs," which tells me the growth in your line item is being driven by measurement availability, not by proven incremental demand.

Strategic direction
You are not competing for conversion; conversion is already decided before the shopper gets there. You are competing for the memory and the preference that makes the shelf moment a formality, and retail media is very good at taking credit for that work while quietly defunding it. Start the holdout test on Monday, because without it every conversation you have about this channel for the next two years is faith. The question I would open a two day session with: if you turned off every retail media network tomorrow, what share of those sales do you honestly believe would disappear, and what would you have to build to be sure?
