About this ebook

AM vs FM explores the captivating history of amplitude modulation (AM) and frequency modulation (FM) radio, detailing their technological development, regulatory environments, and programming shifts. Initially, AM radio dominated as it transmitted audio via amplitude variations, but was susceptible to interference. FM radio later emerged, varying frequency instead, which offered superior audio quality.

The book argues that FM's ascent wasn't just due to technology, but also regulatory decisions, consumer preferences, and programming innovation. The book examines how the Federal Communications Commission (FCC) impacted both AM and FM through regulations like licensing freezes and frequency shifts. It also clarifies how FM's superior audio fidelity and innovative programming formats, such as album-oriented rock, contributed to its eventual success.

The book approaches these topics with clear language and diagrams. Structured chronologically and thematically, AM vs FM begins with the principles of each broadcasting method. It then explores AM's early 20th-century dominance, followed by FM's emergence, struggles, and eventual triumph. The book concludes by analyzing the current state of both AM and FM radio in todayâs digital age.
