Windows, Windows, Windows Everywhere

In the accompanying photo you can see one of the ubiquitous TV screens sprinkled all around the Spanish subway system. They display up-to-the-minute information about arrivals and departures, in real-time, also ads and other commercial announcements. Very useful!
