New York City Transit is stepping up efforts to sell advertising in the subway, and on subway cars themselves. For just the second time ever, a full-length ten-car subway train is completely covered in advertising. Another train is integrating video ads, something that has been used just once before. In addition, this week is a high point for “station dominations,” where one advertiser fills all the ad space in a single subway station, according to MTA spokesman, Aaron Donovan. The holiday season is always the absolute high point for most ad activity.
