The mobile phone has achieved a global presence faster than any other form of information and communication technology. A global multi-billion dollar industry, this small, mundane device is now an intrinsic part of our everyday life. This communications medium has had an immense social and cultural impact and continues to evolve. Talking, texting, photographing, videoing, connecting to a network of other media - the cellphone now seems essential. But, beyond the ways in which it has actively restructured our daily lives, the mobile has changed our sense of ourselves and the way we see the world. The relationship between public and private space, how we view time and space, how we rely on and negotiate social networks - all are increasingly centred on this small piece of technology. Mobile Communications presents a succinct, challenging, and accessible overview of the transformations and challenges presented by this most personal, yet most overlooked technology.
