Book excerpt: The spread of mobile communication, most obtrusively as cell phones but increasingly in other wireless devices, is affecting people s lives and relationships to a previously unthought-of extent. Mobile phones, which are fast becoming ubiquitous, affect either directly or indirectly every aspect of our personal and professional lives. They have transformed social practices and changed the way we do business, yet surprisingly little serious academic work has been done on them. This book, with contributions from the foremost researchers in the field, will be the first study of the impact of the mobile phone on contemporary society from a social scientific perspective. Providing a comprehensive overview of mobile phones and social interaction, it comprises an introduction covering the key issues, a series of unique national studies and a final section examining specific issues.
