(Kate Hinds, Transportation Nation) Beginning today, one of the three shuttle trains running between Grand Central Station and Times Square has what the MTA says is a subway first: an advertiser-sponsored video campaign. The ten-inch screens will be running highlights of the previous night's baseball games. Although the screens are just repeating a 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 dollars a year from advertising -- but isn't saying how much it will earn from the video commercials. The baseball campaign will run on the Times Square Shuttle for a month.
