A new series on the history of shortwave is now available free online. It comes from WNYC in New York City and takes a look not only at how broadcasting on that band began, but what it's become.
"In this cinematic and archive-rich series, we show how shortwave radio went from a propaganda tool for governments, to a propaganda tool for right-wing extremists and cults. We ask why some listeners, pirates, and broadcasters are getting back on this “dying” medium. And we reveal how a little-known battle playing out on the shortwaves right now — a battle between radio fanatics and Wall Street — may serve as a parable for what happens when we cede control of our public airwaves."
Not for everyone but if you were ever a fan of that side of the dial, it might be of interest.
