You know how dystopian films often feature public transit hubs with swipe-able, interactive screens? Well, the future is here.

Metro announced today that high-def digital ad displays are now at 14 of its stations, including interactive touch screen displays at eight of them. In total, workers have installed two of the 65-inch vertical screens at each station, along with a three-panel digital wall at Navy Yard. The agency is looking to mount 22 more vertical screens by the end of the year.

Metro’s advertising contractor, Outfront Media, funded the installation, which the agency says will increase ad revenue four-fold, helping with a potential budget shortfall as ridership declines. WMATA currently makes around $20 million annually in total revenue for ads in stations, and on buses and trains.

Because the high-def screens cycle through ads at a rate of five, 10, or 15 seconds, it can show more advertisements than the stationary ads and allow a greater degree of specificity.

Metro says that advertisers can remotely choose when to run ads so they can target certain audiences. What exactly does that mean? Well, a cafe can advertise its coffee selections and breakfast fare in the morning hours, and then switch to its lunch offerings midday, explains Metro spokesperson Richard Jordan.

Current advertisers include The Smithsonian National Museum of African Art, Smithsonian Freer Gallery of Art, Arthur M. Sackler Gallery, and Iceland Air, according to Metro.
