Marconi : the man who networked the world
Mark Raboy's biography traces the origins and emergence of our present networked system of global communication through the stunning life and career of Guglielmo Marconi.
Handbook of Frequency Allocations and Spectrum Protection for Scientific Uses
The electromagnetic spectrum is a vital part of our environment.Information encoded in the spectrum of radiation arriving at earth from the universe is the means by which we learn about its workings and origin.
Crossing the Pacific
In mediating the human experience of space, communications technologies played an important role along with means of transportation. When wireless telegraphy was introduced to Japan around the turn of the twentieth century, it was not just the military that made successful use of the incipient technology. The adoption of shipboard wireless telegraphy in trans-Pacific navigation helped reshape the Japanese spatial experience of the world’s largest ocean, thanks to extensive coverage by Japanese newspapers. However, technology never marches forward in a straight line as many published histories of wireless telegraphy suggest. The lack of inter-continental wireless telegraphy contributed to communication congestion across the Pacific during World War I, forcing the Japanese government to relax its monopoly while the Japanese business community abandoned its endeavor to build new trans-Pacific submarine cables in favor of wireless telegraphy. By the early 1930s, this public-private partnership enabled Japan to become a major player in international wireless telegraphy which dominated trans-Pacific communication. This article demonstrates that space and technology became mutually constitutive so that the Pacific Ocean could best be described as a single spatial-technological construct.
\This Is Jerusalem Calling\
Modeled after the BBC, the Palestine Broadcasting Service was launched in 1936 to serve as the national radio station of Mandate Palestine, playing a pivotal role in shaping the culture of the emerging middle class in the region. Despite its significance, the PBS has become nearly forgotten by scholars of twentieth-century Middle Eastern studies. Drawn extensively from British and Israeli archival sources,\"This Is Jerusalem Calling\"traces the compelling history of the PBS's twelve years of operation, illuminating crucial aspects of a period when Jewish and Arab national movements simultaneously took form. Andrea L. Stanton describes the ways in which the mandate government used broadcasting to cater to varied audiences, including rural Arab listeners, in an attempt to promote a \"modern\" vision of Arab Palestine as an urbane, politically sophisticated region. In addition to programming designed for the education of the peasantry, religious broadcasting was created to appeal to all three main faith communities in Palestine, which ultimately may have had a disintegrating, separatist effect. Stanton's research brings to light the manifestation of Britain's attempts to prepare its mandate state for self-governance while supporting the aims of Zionists. While the PBS did not create the conflict between Arab Palestinians and Zionists, the service reflected, articulated, and magnified such tensions during an era when radio broadcasting was becoming a key communication tool for emerging national identities around the globe.
Signor Marconi's Magic Box
The extraordinary and often bizarre story of an amateur inventor and how his \"magic box\" changed the world.
Mass communication in Israel
Mass communication has long been recognized as an important contributor to national identity and nation building. This book examines the relationship between media and nationalism in Israel, arguing that, in comparison to other countries, the Israeli case is unique. It explores the roots and evolution of newspapers, journalism, radio, television, and the debut of the Internet on both the cultural and the institutional levels, and examines milestones in the socio-political development of Hebrew and Israeli mass communication. In evaluating the technological changes in the media, the book shows how such shifts contribute to segmentation and fragmentation in the age of globalization.
The ship, the media, and the world: conceptualizing connections in global history
The study of transregional connections is central to the field of global history. This article reflects on the idea of connections from a conceptual viewpoint and treats them as mediators. This will be exemplified by studying the spatial and temporal dimensions of transoceanic steamship passages. The lives of crew and passengers did not go on ‘stand-by’ during such a passage. The case of the flight and eventual capture of Hawley Harvey Crippen will serve as a case in point. Suspected of murder in London, Crippen tried to escape to North America by transatlantic steamer. The captain, however, recognized the fugitive and informed both authorities and media. The ship, whose movements across the Atlantic contributed to the establishment of global connections, thus became tightly entangled in a global media landscape, with newspapers and readers from all over the globe focusing their attention on the small shipboard community. Simultaneously, the steamer became a profoundly secluded place for its passengers, who were cut off from the media flurry surrounding them. The article shifts the principal perspective of the murder case from a terracentric notion of history to a more sea-based narrative. It offers a new historical interpretation of the events and at the same time reconsiders the analytical concept of connections in a broader historical context.
The Ecology of Wireless Newspapers
The phenomenon of “wireless newspapers” at the beginning of the twentieth century combined journalism and airwave transmissions. Years before radio became a mainstream medium, newspapers used and promoted wireless telegraphy to send stories for publication on sea-going vessels and on two islands off the coast of the United States. Drawing on archival research, this historical study uses the concept of media ecology to analyze the factors involved in the introduction and fate of a new technology designed to meet the demand for the latest information.
Tesla
Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the twentieth century. His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft. Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an \"idealist\" inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion. This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.
Empire of the Air
Empire of the Air tells the story of three American visionaries—Lee de Forest, Edwin Howard Armstrong, and David Sarnoff—whose imagination and dreams turned a hobbyist's toy into radio, launching the modern communications age. Tom Lewis weaves the story of these men and their achievements into a richly detailed and moving narrative that spans the first half of the twentieth century, a time when the American romance with science and technology was at its peak. Empire of the Air is a tale of pioneers on the frontier of a new technology, of American entrepreneurial spirit, and of the tragic collision between inventor and corporation.
