In 1983, Simon Goodwin had a strange thought. Would it be possible to broadcast computer software over the radio? If so, could listeners record it off the air and onto a cassette tape? This experiment and dozens of others in the early 80s created a series of cassette fueled, analog internets. They copied and moved information like never before, upended power structures and created a poisonous social network that brought down a regime.

In tape four of Mixtape, we examine how these early internet came about, and how the societal and cultural impacts of these analog information networks can still be felt today.

Mixtape is reported, produced, scored and sound designed by Simon Adler with original music throughout by Simon. Top tier reporting and production assistance was provided by Eli Cohen.

Special thanks to: Alex Sayf Cummings, Martin Maly, Piotr Gawrysiak, Joe Tozer, James Gleick, Jason Rezaian, Gholam Khiabany and Mo Jazi. And to Arash Aziz for helping us every step of the way with our story about Khomeini. And Simon Goodwin for making us that secret code. And to Micah Loewinger to tipping me off to these software radio broadcasts.

As the Vietnam war dragged on, the US military began desperately searching for any vulnerability in their North Vietnamese enemy. In 1964, they found it. It was an old Vietnamese folktale involving a ghost, eternal damnation and fear - a tailor made weaponizable myth. And so, armed with tape recorders and microphones, the military set out to win the war by bringing this ghost story to life.

Today, the story of these efforts and their ghosts that still haunt us today.

Mixtape is reported, produced, scored and sound designed by Simon Adler with original music throughout by Simon. Indispensable reporting and production assistance was provided by Eli Cohen.

In 1946 Bing Crosby was the king of media. He was the movie star, the pop star and his radio show was reaching a third of American living rooms each week. But then, it all started to fall apart. His ratings were plummeting and his fans were fleeing. Bing however, was not going down without a fight.

Today, the story of how Bing Crosby and some stolen Nazi technology won his audience back, changed media forever and accidentally broke reality along the way.

Mixtape is reported, produced, scored and sound designed by Simon Adler with original music throughout by Simon Adler. Invaluable reporting and production assistance was provided by Eli Cohen.
