Services like getchute.com use image recognition to make pictures with logos available to brands. They mostly use the pics for online advertising. In a sense, they broadcast the brand to a bigger audience than what you could make with one person in the street and offer a way to track how many people have seen / will see the ad. How would you compete with those kind of services? What would be the advantage(s) for a brand to offer free tshirts/stickers/caps to people so they can become "living ads"? This kind of sponsor/ad thing has been working with celebrities, do you think everyone can be visible enough to be interesting for big brands?
