It took tens of thousands of years for writing to emerge after humans spoke their first words. It took thousands more before the printing press and a few hundred again before the telegraph. Today a new medium of communication emerges every time somebody creates a new web application. A Flickr here, a Twitter there, and a new way of relating to others emerges. New types of conversation, argumentation, and collaboration are realized. Using examples from anthropological fieldwork in Papua New Guinea, YouTube, university classrooms, and “the future,” this presentation will demonstrate the profound yet often unnoticed ways in which media “mediate” our culture.
