You want to move on from traditional marketing tactics, and embrace the inbound marketing philosophy. You like what you are learning about interactive advertising as a way to achieve this. But you have an existing ad inventory and letting it go seems wasteful. You do want to get better ROI from your advertisements but if you have to build everything from scratch, that purpose seems to have been defeated.
In September 2015, JetBlue airlines invited regular New Yorkers to steal their advertisement. They had put up close to 150 interactive ads – which actually were poster-sized vouchers at bus stops across New York. The ad encouraged the viewer to peel off the ad, and win a prize in return – roundtrip flights, free ice cream, entry to a sporting event, etc. Walking away with a poster-sized coupon under your arm is not discreet at all – but the participants did not care, and this also provided additional exposure to JetBlue. Needless to say, #NYCTakeOff was a hugely successful interactive advertising campaign.
