The subway tunnel as video billboard
If you've been in a subway car in San Francisco, London, Boston, Rio de Janeiro or one of several other cities recently and thought you saw a short film playing along the dark walls of the tunnels, you're not going crazy.
In fact, what you saw was one of the latest forms of advertising technology, which is slowly taking over one of transit riders' last refuges from commercial messages.
The technology, which comes from companies such as Canada's SideTrack and New York-based Submedia, is just what it sounds like: ads displayed on subway tunnel walls in nearly 10 cities worldwide promoting products from companies including Microsoft, Target, Coca-Cola, Reebok and Honda.
