Starting Tuesday, one of the three shuttle trains running between Grand Central Station and Times Square has what the MTA calls a subway first: an advertiser-sponsored video campaign. The ten-inch screens are promoting TBS's coverage of the baseball post-season.

Although the screens are just repeating a TBS commercial right now, subway rider Janet Vasquez appreciates it.

“I think it's great,” she says. “I mean, I enjoy baseball, so it's a little different than looking at the regular, everyday mundane.” 

The MTA says it earns more than $100 million a year from advertising.

The TBS campaign will run on the Times Square Shuttle for a month.
