Abstract

A computer network connects information providers and end-users of network services, facilitates direct information to users, and gathers user responses. The computer network is designed to use otherwise idle bandwidth of the network transmission medium to transfer targeted commercial and non-commercial information to users while minimizing the delay of normal network traffic. User reports containing demographics and user responses are generated ensuring user privacy. Information providers can access user reports without violating user anonymity.
