An information distribution and processing system contains a sender and a plurality of processing units. The sender delivers a set of digital data, without receiving a request signal, to the plurality of processor units. The 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 a database. The database contains additional information. The associated linking reference is used by the database to search for the additional information, and returns the requested information to the user.
