A television system for subway cars (10) includes a plurality of TV monitors (22) mounted at intervals along the cars (10), at the junction of the sidewall and the ceiling, and a central video signal source unit (23) such as a video tape player, video disk player, computer-based digital video recorder or television receiver, connected to the video monitors (22). Programs of short duration, e.g. 5-15 minutes, matching the average length of a subway ride, and comprising advertising messages, news bytes and the like are played and displayed in the monitors repeatedly during the subway ride. |
