Abstract
The presence of persons is detected, for example, by detecting short-range communication devices carried by the detected persons. The interests of the detected persons are then determined by reference to specific interests transmitted by the user devices and/or by reference to customer profile data. The discovered interests of the current detected persons are then used to select content for display on an electronic display during a next display slot. The display is spaced from the zone in which the persons are detected, being located at a downstream location through which most of the detected persons will pass.
