In Canada, telecommunications company Telus sponsored a vending machine that dispenses stuffed animals. But it’s not any ordinary stuffed animal dispensing machine: passers by who tweet with the hashtag #HomeTweetHome would get a free panda bear from the vending machine. It’s not the first time real world machines have been triggered by social media, nor is the technology behind the system truly groundbreaking; it’s a reminder that campaigns utilizing social media to unlock real-world rewards, when used in the right contexts, can be very effective.
