Codebreaker, by Marketplace and Tech Insider

Produced by Marketplace in partnership with Tech Insider, Codebreaker is a podcast that dares to ask — and answer — the fundamental questions about technology that consume us every day. In season one, we’re starting with three deceptively simple words: Is it evil? In each episode, host Ben Johnson applies this question to a different technology. Codebreaker launches November 11, 2015.
