A new perspective on United States software development, seen through the patent battles that shaped our technological landscape This first comprehensive history of software patenting explores how patent law made software development the powerful industry that it is today. Historian Gerardo Con Díaz reveals how patent law has transformed the ways computing firms make, own, and profit from software. He shows that securing patent protection for computer programs has been a central concern among computer developers since the 1950s and traces how patents and copyrights became inseparable from software development in the Internet age. Software patents, he argues, facilitated the emergence of software as a product and a technology, enabled firms to challenge each other’s place in the computing industry, and expanded the range of creations for which American intellectual property law provides protection. Powerful market forces, aggressive litigation strategies, and new cultures of computing usage and development transformed software into one of the most controversial technologies ever to encounter the American patent system.

The Digital Hand, Volume 2, is a historical survey of how computers and telecommunications have been deployed in over a dozen industries in the financial, telecommunications, media and entertainment sectors over the past half century. It is past of a sweeping three-volume description of how management in some forty industries embraced the computer and changed the American economy. Computers have fundamentally changed the nature of work in America. However it is difficult to grasp the full extent of these changes and their implications for the future of business. To begin the long process of understanding the effects of computing in American business, we need to know the history of how computers were first used, by whom and why. In this, the second volume of The Digital Hand, James W. Cortada combines detailed analysis with narrative history to provide a broad overview of computing's and telecomunications' role in over a dozen industries, ranging from Old Economy sectors like finance and publishing to New Economy sectors like digital photography and video games. He also devotes considerable attention to the rapidly changing media and entertainment industries which are now some of the most technologically advanced in the American economy. Beginning in 1950, when commercial applications of digital technology began to appear, Cortada examines the ways different industries adopted new technologies, as well as the ways their innovative applications influenced other industries and the US economy as a whole. He builds on the surveys presented in the first volume of the series, which examined sixteen manufacturing, process, transportation, wholesale and retail industries. In addition to this account, of computers' impact on industries, Cortada also demonstrates how industries themselves influenced the nature of digital technology. Managers, historians and others interested in the history of modern business will appreciate this historical analysis of digital technology's many roles and future possibilities in an wide array of industries. The Digital Hand provides a detailed picture of what the infrastructure of the Information Age really looks like and how we got there.

A comprehensive and fascinating account of electrical and electronics history Much of the infrastructure of today's industrialized world arose in the period from the outbreak of World War I to the conclusion of World War II. It was during these years that the capabilities of traditional electrical engineering—generators, power transmission, motors, electric lighting and heating, home appliances, and so on—became ubiquitous. Even more importantly, it was during this time that a new type of electrical engineering—electronics—emerged. Because of its applications in communications (both wire-based and wireless), entertainment (notably radio, the phonograph, and sound movies), industry, science and medicine, and the military, the electronics industry became a major part of the economy. Dawn of the Electronic Age?explores how this engineering knowledge and its main applications developed in various scientific, economic, and social contexts, and explains how each was profoundly affected by electrical technologies. It takes an international perspective and a narrative approach, unfolding the story chronologically. Though a scholarly study (with sources of information given in endnotes for engineers and historians of science and technology), the book is intended for the general public.?Ultimately, it tells the story of the development of a new realm of engineering and its widespread applications during the remarkable and tragic period of two world wars and the decades in between.

Thanks to inexpensive computers and data communications, the speed and volume of human communication are exponentially greater than they were even a quarter-century ago. Not since the advent of the telephone and telegraph in the nineteenth century has information technology changed daily life so radically. We are in the midst of what Gerald Brock calls a second information revolution. Brock traces the complex history of this revolution, from its roots in World War II through the bursting bubble of the Internet economy. As he explains, the revolution sprang from an interdependent series of technological advances, entrepreneurial innovations, and changes to public policy. Innovations in radar, computers, and electronic components for defense projects translated into rapid expansion in the private sector, but some opportunities were blocked by regulatory policies. The contentious political effort to accommodate new technology while protecting beneficiaries of the earlier regulated monopoly eventually resulted in a regulatory structure that facilitated the explosive growth in data communications. Brock synthesizes these complex factors into a readable economic history of the wholesale transformation of the way we exchange and process information.

Grossman, Times Higher Education Supplement [UK] Reviews of this book: Brock traces a phenomenon he refers to as the 'second information revolution.' According to Brock, there have been two times in history when information technology has dramatically changed daily life. The first 'information revolution' occurred with the advent of the telephone and telegraph, which made communication less expensive and more readily available. The second information revolution is currently in progress...A concise, thorough, and well-written history of the transformation in exchanging and processing of information. --K. A. Coombs, Choice
