O’Grady has more on the latest push to find non-tax sources for dollars:

The tunnel ads would show a string of varied images that, when viewed from a passing train, would move like a flip book. A similar effect is visible in a subway artwork called Masstransiscope between the Manhattan Bridge and the DeKalb Avenue station in Brooklyn. As the D train glides by an unused station at Myrtle Avenue, painted images flash behind vertical slits and appear to be animated.

Donovan said most ideas for non-traditional ad placement come from advertisers themselves. In recent years, the MTA has permitted video on the outside of buses and ads that wrap entire train cars, like the 6 train that became a long rolling ad for Target last fall, when the company opened a store on 116th Street in Harlem.

Then there is a program called “station domination,” in which a single company plasters ads on multiple surfaces — columns, stairwells, turnstiles — throughout a subway station. Ads at Union Square Station have even been projected onto floors and walls. And now the MTA website displays ads for free credit checks and the Crate & Barrel wedding registry.

Over the past few years, the MTA has seen a marked increase in advertising revenue. Despite a recession that has hit the advertising industry particularly hard, the authority drew in $109 million annually in 2009 and 2010 and has seen that total annual take increase from $27 million just 20 years ago. The authority is hoping to realize $120 million in sales this year.

These days, ads are everywhere underground. From branded stations to fully wrapped train cars, we see commercial space throughout the system, and the in-tunnel ads will be just another source of revenue upon which transit agencies throughout the world have long relied. For a few dollars more, I’ll take it.
