POINT OF PURCHASE ADVERTISING SYSTEM Abstract of the Disclosure A point of purchase advertising system is provided which senses the presence of a person in the vicinity of an advertising display and thereupon renders an appropriate advertisement such as a recorded verbal message or a visual or aural demonstration. In preferred forms, the overall apparatus includes an ultrasonic sensing circuit for detecting the approach of a potential customer, an advertisement giving device, typi- cally an endless tape playback unit and a coupled speaker, and a controller for operation of the playback unit in response to detection of a cus- tomer. A voice operated relay circuit is advan- tageously coupled with the audio output of the playback unit and the playback controller, so that operation of the playback unit is maintained until the entire recorded advertisement has been given.
