A History of Communications advances a new theory of media that explains the origins and impact of different forms of communication on human history.

Spies, secret societies, religious cults as well as anyone who has used an ATM or the internet rely on the making and breaking of codes for security. Like a spy novel combined with the technology of a Tom Clancy thriller, Codes, Ciphers and Other Clandestine Communication successfully interweaves technical explanations of each important coding method with their place in the shadowy world of secret communications. Special chapters teach some easy and fun ciphers that readers can make and use at home. Hundreds of illustrated examples take the reader step-by-step through the foundations of cipher making from Caesar's cipher to World War I's ADFGX and beyond. Detailed diagrams and line drawings of each coding machine will delight technology buffs and war-machine aficionados. Packed with historical anecdotes about cryptography's most famous pioneers and practitioners, this book covers the development of codes through the ages from the druids, Marie Antoinette, Aaron Burr, Confederate spies in the Civil War to the Freemasons, German U-Boat Wolf Packs, the KGB, and much more.

A History of Communications advances a new theory of media that explains the origins and impact of different forms of communication on human history.

In the 1980s and 1990s, the internet became a major player in the global economy and a revolutionary component of everyday life for much of the United States and the world. It offered users new ways to relate to one another, to share their lives, and to spend their time—shopping, working, learning, and even taking political or social action. Policymakers and news media attempted—and often struggled—to make sense of the emergence and expansion of this new technology. They imagined the internet in conflicting terms: as a toy for teenagers, a national security threat, a new democratic frontier, an information superhighway, a virtual reality, and a framework for promoting globalization and revolution.Schulte maintains that contested concepts had material consequences and helped shape not just our sense of the internet, but the development of the technology itself. Cached focuses on how people imagine and relate to technology, delving into the political and cultural debates that produced the internet as a core technology able to revise economics, politics, and culture, as well as to alter lived experience. Schulte illustrates the conflicting and indirect ways in which culture and policy combined to produce this transformative technology.

The book explores the background and motivation of these pioneers and the social and economic environment in which they worked. The significance of each innovative step is shown in terms of the impact - in scale and relevance - on today's communications world. John Bray also looks to the future for innovations yet to come. This book will be interest to all those interested in the human thread running through the history of technological advances in telecommunications and broadcasting.

The magnificent, unrivaled history of codes and ciphers—how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage—updated with a new chapter on computer cryptography and the Ultra secret.Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

Invaluable guidance on the most important legal issues facing nonprofits today Internet communication is the lifeblood of countless nonprofit organizations, yet there exists no specific law to provide for its regulation. Without solid legal guidance, nonprofits risk not only missing out on the unlimited opportunities that the Internet has to offer, but also jeopardizing their tax-exempt status. The Nonprofits' Guide to Internet Communications Law analyzes and explains the laws applicable to Internet communications by nonprofit organizations. Nonprofit law expert Bruce Hopkins writes that with Congress and government agencies reluctant to create new law, it will ultimately be up to the courts to determine the future of Internet law affecting nonprofit organizations. Extrapolating from the underlying principles of existing law, Hopkins addresses the legal ramifications of Internet business activities, charitable-giving administration, fundraising programs, lobbying, political campaign activities, and more. The Nonprofits' Guide to Internet Communications Law proves an unparalleled resource for this emerging field.

Fifty years ago, the political whistle-stop tour was thus named because trains blew their whistles twice when making unscheduled stops in backwater towns. Like its distant cousin, the electronic whistle-stop brings the candidate's message directly to the people, but with one outstanding difference: the new whistle-stop offers politicians an accuracy, efficiency, and success at voter persuasian unimaginable to by earlier whistle-stoppers such as Harry Truman.As Selnow shows, American political campaigns have an extraordinary affinity for electronic devices. They have seized upon electronic bulletin boards, home pages, and electronic libraries. Since political campaigns are communication campaigns, Selnow concludes that candidates who successfully inform, persuade, enlighten, and even confuse voters will win votes. Selnow also examines the debate between those who argue that new technologies have improved efficiency and those who believe that the innovations have affected society in other ways. Scholars and students of American political communication must read this book; the lively style will also make it exciting reading for anyone interested in this new political tool.
