Around the year 2000, a new research topic emerged in the social sciences and the humanities: mobile telephony. Drawing on earlier scholarship on the classic phone, the internet, and the information society, and applying the conceptual tools of communication theory, sociology, psychology, political science, etc., mobile telephone research began as, and continues to be, an interdisciplinary enterprise. Nonetheless, over the years an impressive array of paradigmatic research results has crystallized into what can be termed as the new discipline of Mobile Studies. Summarizing these results, the volume also opens up new perspectives on mobile telephony in the age of telecommunications convergence.
