Communication scholarship has not enjoyed the same kind of theoretical cohesion or ontological security as some disciplines. The field¿s intellectual «roving eye» and resistance to establishing a single core body of knowledge has inspired serial rounds of soul-searching and existential doubt among communication scholars, on one hand, and celebration and intellectual adventurism, on the other. The theme of the 2013 ICA annual conference thus raised an interesting question: For a field that is perpetually in flux and «decentered», what exactly is, or should be, challenged? How, and by whom?
The chapters in this collection, chosen from among the top papers presented in London, suggest that the challenges themselves are constantly being reinvented, broken down and reorganized. The communication discipline undergoes continuous change rather than following an orderly, stepwise path toward the neat, complete accumulation of knowledge. The chapters challenge familiar approaches, notions or assumptions in communication research and scholarship and reflect on the field¿s multifaceted and increasingly open character in an era of shifting social relations, formations and technologies.
