The telephone has played a central role in shaping the way we communicate. From the telegraph in the 19th century through the mobile phone of today, the technology of the telephone has drastically altered how people work, how they keep in touch with friends and loved ones, and how they organize their daily lives. It has also been crucial in enabling governments and large organizations to extend their influence, both within and across nations, and has required wide-ranging changes in the law and in business practices. This volume in the Greenwood Technographies series examines the life story of the telephone and shows how this ubiquitous technology so completely impacts our lives.
