The narrative of digital transformation in retail has been remarkably consistent. First, get online. Then build an app. Then optimize checkout. Add loyalty points, push notifications, maybe a chatbot.
For years, this was the right strategy. It moved retail from physical-only to omnichannel, giving customers access, convenience, and choice.
But something fundamental shifted at Google I/O 2026.
The conversation is no longer about getting customers to your storefront—digital or physical. The question retailers must now answer is: When your customer's agent comes shopping, will your business be ready?
This is the move from HTTP/HTTPS (where humans browse sites) to the Universal Commerce Protocol (UCP) (where agents act across platforms). It redefines not just the technology of retail, but the entire relationship between businesses, customers, and shopping itself.
