Abstract

A system for distributing educational information in digital form to a plurality of schools simultaneously transmits the information via a satellite (15) to FM stations (18) which retransmit to schools having receivers for receiving the information and a main computer (101) for storing the information. Access to the information is subsequently provided to a plurality of students via classroom computers (111) and individual terminals (121). Usage and performance data is automatically stored in the main computer (101) and sent to the sender by dial-up modem (105) to keep track of usage and to permit billing usage and royalty charges.
