BBC World Service: Why Do We Need Cash?

In his BBC World Service programme The Why Factor, Mike Williams searches for the extraordinary and hidden histories behind everyday objects and actions in always fascinating, twenty minute episodes.

In the July 5, 2015 episode, I am one of those with whom Mike explores the past, present, and future of one of the most basic, but underrated, cogs of our modern economic systems, as he asks Why Do We Need Cash?

Many more episodes of The Why Factor are available here.
