A central scheduling program transmits and runs messages, such as advertisements and public announcements, at particular billboards located in an airport (104), for example, based on flexible audience targeting schedule rules or algorithms, which may include flight departure and arrival times (120), billboard location (130), location attributes and characteristics, audience demographics for certain airports and flights (140), and other relevant information (150). This program may also apply to bus stations, train stations, and other transportation stations, as well. A network of digital billboards provides the ability to target messages, such as advertisements and public announcements, to a targeted audience. The digital format further enables advertisements to change and be updated periodically (170). |
