A few months ago I featured Zenith’s Wincharger wind generator systems, part of the farm electrification movement of the New Deal.
Noticed this ad in a 1947 broadcast trade journal:
The Wincharger factory was already making short towers for the generators. After most farms were hooked up to the grid, Zenith switched to tall towers for its core radio business. Smart move. Amortize, amortize, amortize.
