Geographical interest in the systematic study of communication can be traced to the writings of
Richard Hartshorne in the 1930s. Hartshorne considered language to be a key element forming culture regions, meaning that the dominant language is similar within a particular culture region and it changes when one leaves a culture region. A very different aspect of communication became the focus during the 1950s and 1960s as geographers began to measure and model the interactions between locations. In this case, geographers involved in the
quantitative revolution explained the accelerating flow of information between
locations in terms of "time-space convergence" and "human extensibility." It was not until the 1970s that geographers began to focus on communications in terms of content, considering questions of symbolism,
representation,
metaphor,
iconography and
discourse. This interest first took form in geographical research that drew on
humanism,
phenomenology and
hermeneutics. By the 1990s, this approach shifted towards a more critical sensibility unpacking the various meanings of
landscape. Geographers researching communication over the past two decades have extended these research areas while carrying forward early insights regarding the importance of communication to the formation of regions, the rate of information flow as a measure of spatial interaction, and the association between landscape and representation. New approaches to communication have been advanced under the frameworks of
non-representational theory,
actor-network theory, and assemblage theory. Equally important is the effort to think through digital code and its relationship with space. == Evolution of Geographic Communication ==
