Airport flight information display systems that show arrival and departure times have been around for decades. In recent years, some enterprising airports, rail stations, and bus depots have upgraded these screens to show real-time information on trip delays, weather, news and sports coverage, stock market updates, and other information that passengers might want. These next-generation displays can reduce the workload for staff members (since fewer travelers are asking them for schedule updates), and also cut down on the perceived waiting time for passengers. In some cases, advertising time is sold to marketers who want to reach travelers. For example, a restaurant in New York might advertise in airports nationwide, but only at the gates that have flights heading to New York.
