Riding the Red Line T inbound from Harvard Square, I was glancing out the windows of the train, looking at the nothingness of the black walls of the subway tunnel. Then all of a sudden I saw an ad. It lasted long enough for me to understand the ad (but not long enough for me to remember, more than a week later, what product the ad was promoting.)
I thought to myself, this is cool, but enough is enough. Do we have to have advertising EVERYWHERE?
Nonetheless, it was still pretty cool.
Thinking about this on Sunday (the day I am actually writing this post), I Googled "advertising in subway tunnels." I found a blog on advertising technology, that had a post about this very spot on the T. It included this quote Forbes about the technology used.
Submedia, cofounded
by Spodek and Matthew Gross in 1999, produces 15- to 20-second animated
ads that appear on subway tunnel walls. This is accomplished through a
series of backlit pictures which Spodek compares to "the frames in a
film reel." The pictures, printed by the U.K.'s Photobition Group on
Kodak transparencies, spring to life as the train speeds by, creating a
fluid film and giving passengers the effect of being inside a giant
flip book."
