About this episode
EPISODE 1: You know AM and FM radio. But did you know that there is a whole other world of radio surrounding us at all times? It’s called shortwave — and, thanks to a quirk of science that lets broadcasters bounce radio waves off of the ionosphere, it can reach thousands of miles, penetrating rough terrain and geopolitical boundaries. How did this instantaneous, global, mass communication tool — a sort of internet-before-the-internet — go from a utopian experiment in international connection to a hardened tool of information warfare and propaganda?
