Telecommunications policy profoundly affects the economy and our everyday lives. Yet accounts of important telecommunications issues tend to be either superficial (and inaccurate) or mired in jargon and technical esoterica. In Digital Crossroads, Jonathan Nuechterlein and Philip Weiser offer a clear, balanced, and accessible analysis of competition policy issues in the telecommunications industry. After giving a big picture overview of the field, they present sharply reasoned analyses of the major technological, economic, and legal developments confronting communications policymakers in the twenty-first century.

Donald Keyhoe was there first. He didn't invent the UFO phenomenon, but he became its first authoritative private spokesman. In 1949, TRUE magazine asked aviation writer and retired Marine Corps Major Donald Keyhoe to look into the flying saucer enigma, which had burst onto the scene just two years previously. With information from his friends in the military, Keyhoe concluded that the objects came from outer space and that the Air Force was covering up the story to prevent panic.
"The article caused a sensation and a year later Keyhoe expanded it into this landmark book, THE FLYING SAUCERS ARE REAL. In a personal, no-nonsense style, Keyhoe provides the details of his investigation: he talks with the witnesses, reviews the history of the phenomenon, and attempts to pry open the secrecy lid the Air Force had clamped down on the subject. Keyhoe would go on to write four more books on the subject and in 1957 he became director of the National Investigations Committee on Aerial Phenomena, without a doubt the most influential private UFO organization of all time. But it is this book, which sold a half-million copies, that inspired hundreds of people to take up the UFO cause and established the core elements of UFO mythology, which the government has attempted to counter–unsuccessfully, I might add–to this very day.

This book constitutes the refereed proceedings of the Second International Conference on Technologies for Interactive Digital Storytelling and Entertainment, TIDSE 2004, held in Darmstadt, Germany in June 2004. The 30 revised full papers presented were carefully reviewed and selected for inclusion in the book; also included are the abstract of a keynote talk and 10 descriptions of demonstrations and interactive exhibitions of computer art. The papers are organized in topical sections on interactive storytelling, virtual humans, authoring, mobility, learning, theory, applications, gaming, and demonstrations and exhibitions.
Interactive Digital Storytelling has evolved as a prospering research topic banding together formerly disjointed disciplines stemming from the arts and humanities as well as computer science. It’s tied up with the notion of storytelling as an effective means for the communication of knowledge and social values since the existence of humankind. It also builds a bridge between current academic trends investigating and formalizing computer games, and developments towards the experience-based design of human-media interaction in general.
