Book excerpt: Mobile communication has dramatically changed over the past decade with the diffusion of smartphones. Unlike the basic 2G mobile phones, which "merely" facilitated communication between individuals on the move, smartphones allow individuals to communicate, to entertain and inform themselves, to transact, to navigate, to take photos, and countless other things. Mobile communication has thus transformed society by allowing new forms of coordination, communication, consumption, social interaction, and access to news/entertainment. All of this is regardless of the space in which users are immersed. Set in the context of the developed and the developing world, The Oxford Handbook of Mobile Communication and Society updates current scholarship surrounding mobile media and communication. The 43 chapters in this handbook examine mobile communication and its evolving impact on individuals, institutions, groups, societies, and businesses. Contributors examine the communal benefits, social consequences, theoretical perspectives, organizational potential, and future consequences of mobile communication. Topics covered include, among many other things, trends in the Global South, location-based services, and the "appification" of mobile communication and society.
