At the turn of the twenty-first century, a new form of advertising is born that operates in the street but relies on the digital to take the most unexpected and spectacular forms. All the street furniture goes from lamp post to cash dispenser, from the simple bench to the entire bus stop. The city is an infinite playground that only has the sky as its limit. The "guerrilla marketing" or "ambient marketing" creates the buzz, so that the dumbfounded or amused passerby shares it on social networks. Thanks to giant objects, trompe-l'oeil games and many more and more funny and audacious jokes, street advertising makes the spectator fall back into childhood. This book in the shape of a world tour stops on the most creative projects of the last ten years.
