Ubiquitous mobile communication satisfies fundamental human needs. At the same time mobile telephony is an answer to challenges represented by the complexities of a decentralized global mass society – our postmodern society. With the mobile phone dissolving the boundaries between private and public, work and leisure, and increasingly even between rich and poor, some basic patterns of life, labour, love, war, travel, business, and politics are changing. This volume contains papers by, among others, Kenneth Gergen, Richard Harper, Joachim Höflich, James Katz, Joshua Meyrowitz, and Mark Poster.

Kristóf Nyíri has published widely on Wittgenstein, Austrian intellectual history, and the philosophy of communication. He directs the interdisciplinary research program "Communications in the 21st Century", conducted jointly by the Hungarian Academy of Sciences and T-Mobile Hungary.
