Over the last few years, vending machine promotions have become an extremely popular way to get the public excited about just about anything from salad to drinking water. But rather than making the experience of getting something from a vending machine more complicated than it needs to be, Canadian advertising agency TAXI set up 'Project Vend.'
Instead of trading tweets or using facial recognition to detect smiling faces worthy of getting a treat, these ordinary vending machines placed outside only accepted loose change. At first, people were confused, but soon people were lining up to get snacks. As TAXI notes, Project Vend didn't spark huge conversations on social media, but what it did do was make sure that all of the inventory sold.
