The Vacuum Tube Economy: Patents, Prices, and Amateur Radio
How Component Costs Shaped Early Broadcasting

About this book:

Discover how a single glass bulb wired with glowing filaments became the invisible gatekeeper of the 20th‑century media revolution. *The Vacuum Tube Economy* takes you inside the secret world where patents, price wars, and grassroots ingenuity turned a five‑dollar component into the engine that powered everything from Titanic‑era maritime radios to Depression‑era living‑room sets. Follow the daring battles of GE, Westinghouse, AT&T, and RCA as they forged a patent pool, the rebellious tinkerers who rebuilt tubes in their basements, and the global ripple effects that still echo in today’s chip wars and right‑to‑repair debates.

Through vivid chapters—from the Edison Effect and Fleming’s diode to wartime standardization, the rise of the All‑American Five, and the post‑war surplus boom—you’ll see how cost, not just curiosity, dictated who could broadcast, who could listen, and what technologies survived. Learn how amateurs turned scrap into signal, how bootleg tube markets challenged corporate monopolies, and how each technical leap was driven as much by economics as by physics.

Whether you’re a radio aficionado, a history buff, or anyone fascinated by the hidden economics that shape our devices, this book reveals the untold story of the component that made mass communication possible—and shows why the struggle over cheap, open hardware is as relevant now as it was a century ago.
