The channels are the easy part
Most retailers already run the same offer in four places — the email, the app, the store screens and the in-store audio — with each system deciding on its own who sees what. Adding another channel does not fix that. One shared definition of the audience does.
One platform, two ways to deliver
Most of a retail media platform is channel-neutral: campaigns, creative, audiences, users and rights, network management and measurement. Only the last step differs — a player drives a screen, an ad server fills a placement in an app — so In-Store IMPACT keeps one core and puts only delivery at the edge.
