All podcasts, regardless of their format, are a creative endeavor. But some podcasts are just more complex. Enter, Bellwether, the latest offering from award winning podcast and radio producer, Sam Greenspan.

Sam is the founding producer of 99 Percent Invisible and has a number of impressive credits to their name. The City from USA Today, the TED Radio Hour at NPR and Radiotopia’s Spacebridge to name a few. They’ve also lectured and taught radio and podcasting around the world. In November of 2021, Sam was hired as a Senior Producer at Vice Audio.

So when Bellwether was released, the podcasting world took notice. Bellwether was a five year effort from one of the most brilliant minds in podcasting. This five episode narrative weaves together both real world reporting (stories Sam personally covered) and a fictitious Sci-Fi story arc. Described by Sam as a “new podcast of speculative journalism” Bellwether examines what the world is through the lens of what it might become.
