Lately New York’s subway cars have gotten a little ad-crazy, plastered from one end to the other in promotional campaigns for the island of Aruba, ABC’s Pan Am, or those two-year “business institutes†that train you to work for the TSA. Some trains are even being sheathed in ads on the outside. Now HBO is taking the concept one step further, by paying the MTA $150,000 to run a Prohibition-era train between Times Square and 96th Street on the 2 and 3 lines every Saturday and Sunday in September. Whatever it takes to keep subway fares from jumping again, we say. [Metropolis/WSJ]
