Abstract
Abstract The period for which advertisements are displayed on display screens is monitored by coupling the displaying time with the time of a telephone call from a public telephone booth near the display panel. Preferably, the call made from this booth is paid with a pre-payment memory card. This memory card also has a memorizing zone in which it is possible to record an advertisement which is precisely the advertisement to be displayed.
