It is a description of the context in which we are writing, and thus also the context that frames this investigation, namely that of postmodernity. Through the thought of postmodernity this chapter will give a characterisation of the world as we see it today and the individuals that inhabit it. It will explain how we as individuals see ourselves and understand the world, and how we make sense of our lives. It is a characterisation that is necessary to make, as the thoughts of postmodernity not only permeate the background for the street art movement but just as much communication theory of today. It is thus both the precondition for our investigation as well as it is the frame in which we have to envision our results. This investigation will ultimately lead to a definition of the street art media and the motives behind it. Moreover, we will look at the city as an active part of the street art expression, explaining its significance to the media.
