Why just tell people what you do when you can actually show them?
Take this ad from Adidas' "Impossible is Nothing" campaign as an example. Sure, the bus is plastered with the campaign's regular ads -- but check out the guy who's actually dragging the bus.
Now that's what I call walking the talk.
Implications - Taking advertising to the streets is a reaction to increasing protests around the world. More and more, people are occupying public space and re-appropriating traditional environments for alternative purposes -- whether it be for revolutions or for products. This trend translates into the fusion of performance art, advertising and retail in order to catch the attention of a large segment of potential consumers.
