A sweep of radio history from its birth as Marconi's "wireless telegraph" through its status under deregulation, this book analyzes the changing medium's social, political, and cultural impact. It casts light on many topics, including the roles of women and African Americans, programming sources outside the Hollywood-Broadway nexus, and more.

What became of radio after its Golden Age ended about 1960? Not long ago Arbitron found that almost 93 percent of Americans age 12 and older are regular radio listeners, a higher percentage than those turning to television, magazines, newspapers, or the Internet. But the sounds they hear now barely resemble those of radio's heyday when it had little competition as a mass entertainment and information source. Much has transpired in the past fifty-plus years: a proliferation of disc jockeys, narrowcasting, the FM band, satellites, automation, talk, ethnicity, media empires, Internet streaming and gadgets galore... Deregulation, payola, HD radio, pirate radio, the fall of transcontinental networks, the rise of local stations, conglomerate ownership, and radio's future landscape are examined in detail. Radio has lost a bit of influence yet it continues to inspire stunning innovations.

In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.

Long before the Arab Spring and its use of social media demonstrated the potent intersection between technology and revolution, the Mexican Revolution employed wireless technology in the form of radiotelegraphy and radio broadcasting to alter the course of the revolution and influence how political leaders reconstituted the government. Radio in Revolution, an innovative study of early radio technologies and the Mexican Revolution, examines the foundational relationship between electronic wireless technologies, single-party rule, and authoritarian practices in Mexican media. J. Justin Castro bridges the Porfiriato and the Mexican Revolution, discussing the technological continuities and change that set the stage for Lázaro Cárdenas’s famous radio decree calling for the expropriation of foreign oil companies. Not only did the nascent development of radio technology represent a major component in government plans for nation and state building, its interplay with state power in Mexico also transformed it into a crucial component of public communication services, national cohesion, military operations, and intelligence gathering. Castro argues that the revolution had far-reaching ramifications for the development of radio and politics in Mexico and reveals how continued security concerns prompted the revolutionary victors to view radio as a threat even while they embraced it as an essential component of maintaining control.

Uses four factors--energy capture per capita, organization, information technology and war-making capacity--to attempt to show which world regions were the most powerful throughout all of human history.

This history of radio news reporting recounts and assesses the contributions of radio toward keeping America informed since the 1920s. It identifies distinct periods and milestones in broadcast journalism and includes a biographical dictionary of important figures who brought news to the airwaves. Americans were dependent on radio for cheap entertainment during the Great Depression and for critical information during the Second World War, when no other medium could approach its speed and accessibility. Radio's diminished influence in the age of television beginning in the 1950s is studied, as the aural medium shifted from being at the core of many families' activities to more specialized applications, reaching narrowly defined listener bases. Many people turned elsewhere for the news. (And now even TV is challenged by yet newer media.) The introduction of technological marvels throughout the past hundred years has significantly altered what Americans hear and how, when, and where they hear it.

With a current world population that exceeds seven billion, resource consumption awareness is more important than ever. Investing in sustainable technologies and renewable resources is a necessary step to ensure the future quality of life of all human beings. The Handbook of Research on Sustainable Development and Economics explores topics such as poverty, gender equality, health, security, and the environment through global empirical studies and fundamental frameworks. With the goal of promoting sustainable techniques for the global future, this handbook is a critical reference for business leaders, educators, policymakers, environmental specialists, and the public at large.
