Algorithms and software are starting to catch the interest of social scientists and humanities scholars, having become somewhat of a buzzword in media and communication studies during the past years. Yet we are only at the beginning of understanding how algorithms and computation more broadly are aecting social life and the production and dissemination of knowledge as we know it. The introductory chapter sketches the contours of an algorithmic media landscape as it is currently unfolding by focusing on the ways in which Facebook friendships are programmatically organized and shaped through algorithmic systems. The chapter introduces the concept of “programmed sociality” to draw attention to software and computational infrastructure as conditions of possibility for sociality in digital media.
