An information distribution and processing system contains a remote site, a sender and a plurality of processing units. The remote site contains a first set of digital data and one or more communication channel for receiving a request from the processing units. The sender delivers a second set of digital data to the processing units. In one embodiment of the present invention, some of the processing units contain a timing device for automatically receiving the second set of digital data at predetermined times. In another embodiment, the communication channel is wireless. The second set of digital data contains a first set of displayable data, a second set of displayable data, at least one non-displayable symbol, and at least one linking reference associated with the second set of displayable data. If desired, a user can select the second set of displayable data. The associated linking reference is sent to the remote site. The associated linking reference is used by the remote site to search for the additional information, and returns the requested information to the user.
