Electronic audience polling system
 An audience polling system includes a plurality of wireless transmitters, each transmitter capable of transmitting a pulse of electromagnetic energy on a selected one of a group of predetermined frequencies. Each frequency selected on which to transmit corresponds to one of a group of suggested responses to a given stimulus. The polling system includes a receiver for receiving the transmitted pulses and electronic counters for tallying the number of pulses received on each of the selected frequencies. An electronic display presents the results of the tallying for observation by the audience or others.
