Abstract
One or more messages, such as an ad, is selected and played to potential passengers at a shuttle landing, such as an elevator corridor, waiting for a car to respond to a call, the ad being selected to play completely within the time estimated for the car to respond to the call. In an elevator or other shuttle car, one or more ads are selected having a playing time less than the time it takes to reach the next scheduled landing stop. Ads are arranged in groups of ranges of playing times or are selected in series until the time is exhausted, or both. The car load and the identification of the ads (if they are completed) are recorded for billing purposes. Ads are prevented from playing while passengers enter and exit the cars (except for passengers traveling in the opposite direction from those whose call started the playing of an ad). Other criteria such as time of day, day of week, load in the car, and landing (floor) of the system can be used to limit ad selection. A background program may be played when ads are not playing, if desired.
