"Let's turn customers' shopping carts into improvised videos." It's an idea so brilliantly quirky as to border on insane - but Jet.com's one-day branding spectacular is one of the best examples of integrated marketing communications in action I've seen recently. The premise of the campaign, called #JetSpree, was simple but groundbreaking. One day only, during predefined hours, Jet.com asked shoppers for permission to turn their shopping carts into what they called "on-the-spot video." In essence, their purchases would be used as the inspiration for videos involving double dutch jump roping, a barbershop quartet, pantomime, yodeling, improv comedy, dancing toys and even a turtle. The videos were then shared on YouTube and social media during the event.
