Art as we know it is changing dramatically, but popular and critical responses are lagging behind. In this edgy illustrated essay, David Joselit describes how art and architecture are transforming in the age of Google. Under the double pressure of digital technology , which allows images to be reformatted and disseminated effortlessly, and the exponential acceleration of cultural exchange enabled by globalization, artists and architects are emphasizing networks as never before. Some of the most interesting contemporary work in both fields is now based on visualizing patterns of dissemination after objects and structures have been produced, and after they have entered different and even established networks. Acting like human search engines, artists and architects sort, acquire and reformat existing content.
