A system gathers commerce information and distributes advertising using an integrated global computer system. The integrated system includes a local area network (LAN) in retail stores that interconnects cash registers in the stores. The LAN is also interconnected with electronic billboards that are mounted to the checkout aisles near the cash registers. Sales data is registered by each cash register, recorded as a customer record, and electronically transferred to a main server connected to the LAN. Periodically, this main server uploads this sales data to a central data server through using a global computer network. Based upon the customer purchase information stored in this central data server, it is possible to purchase advertising. The purchased advertisements are transmitted to the individual stores through the global computer network and shown on electronic billboards that are fixed to the checkout aisles in retail stores.
