I highly recommend this episode of Econtalk with Matt Ridley talking about how innovation makes inventions useful by making them available, affordable and reliable.
The Academy of Ideas podcast is a good overview of the book’s key points about how innovation works and made me feel that I probably didn’t need to read it. This excellent interview with Russ Roberts is a richer discussion of a few themes with wonderful and entertaining examples which made me really keen to get into the book.
