It’s so advanced, you don’t even have to be close to the billboard to interact with it!  As a part of their “Bank Human” campaign, TD Bank in New Jersey invited consumers to “say ‘hi’ and we will say ‘hi’ back.” They ran a billboard campaign in New York, Boston and Philadelphia that would “talk back” to anyone who tweeted to #humanhello.  The billboard nearest to the person’s location would then flash a personal message and a photo of the message would be tweeted back to the sender.  The bank’s ad agency, Tierney, says interaction of any type is a great way to engage consumers.  They say this campaign “broadened the potential audience of what could have been a limited out of home campaign.”  Response to the campaign has been positive, with one person even tweeting that the billboards made his commute easier…the tweet said, “Driving 2 hours each way is a little better with the funny #humanhello billboards.”
