Abstract
A delivery system for the selective dissemination of information to subscribers uses a non-telephone authorizing signal to authorize the subscriber stations for which information is to be delivered. The subscriber station, when authorized, dials up a predetermined number to form a telephone channel through which the information is delivered. The apparatus and method eliminate the need for a dedicated channel serving the station and preferably the subscriber station only seizes a telephone channel when available and therefore may share an existing telephone channel.
