I spent Foursquare Day today checking in just about anywhere I legitimately could. I was caught up in the excitement of what had been declared an official holiday in NYC Starting in Rockefeller Plaza, and needing to get to Christopher St in the West Village, my friend Rachel indulged my need for Foursquare venues and walked with me to the Times Square.

Rachel’s patience continued when I noticed that there was something peculiar about the pictured ad. Suspicion became certainty as I called the phone number displayed on the advertisement, and my dial pad became a remote control for the giant screen across Broadway and 7th Ave.

Using my phone, I scrolled through different examples of what someone could do on their phone, using Sprint’s 4G network.

Sprint took ad space, and used it to crate something that benefited it’s audience. Really cool, super effective. Win.

What do you think of an interactive ad?
