Looking through a historical lens, this new casebook examines the evolution of telecommunication law, policy, and technology from the telegraph to the Internet. It examines six key industries: broadcast, cable TV, telephone, satellite, wireless, and the Internet. The book’s novel format begins with introductory chapters analyzing the nature of spectrum and regulation of spectrum-based services and the history and technology that link the regulation of telegraph-to-telephone-to-the-Internet. This casebook analyzes conceptions of the public interest as defined by statute, case law, and FCC and state decision-making. It contrasts the legal and economic standards used by antitrust law as compared to communications law. It examines telecommunication regulation through the lens of five key concepts: functionality, ownership or licensing, access, speech, and the public interest. The casebook offers projects and hypotheticals that support analysis of issues from the perspective of constitutional, administrative and communications law, as well as statutory issues raised by communications and information technology regulation.
