“Flip book” subway ads old news in Boston but a big deal in L.A.
The Los Angeles Times has a story on subway billboards that appear as videos to the passengers gliding by them:
On Tuesday, commercial messages on mass transit in the Southland reached a new frontier when subway riders began seeing a 15-second video floating outside the train’s window in a dark tunnel near Universal City.
The first ad was a short promo for the film "Speed Racer," featuring the main character’s car zipping and flipping about. An ad for Target began showing later in the morning, complete with dancing models.
