Abstract: Apparatus for presenting information to a group in attention in a manner whereby the rate of information presentation is variable with respect to the group as a whole; the apparatus consists of a reproducing device for generating both an information signal and a control tone for distribution to a plurality of informationreceiving stations. The distribution system provides for the reproduction of a series of predetermined amounts of information, each amount or serially occurring portion being terminated by a control tone which ceases reproduction and enables a listener response tally. Thereafter, each listener signifies readiness to continue by means of a switch closure, and after a predetermined number of such switch closures the reproducing device is restarted to generate the next segment of its information.
