For those happy to pop on their headphones and listen to a series of fascinating podcasts, I can fully recommend '50 Things That Made the Modern Economy' from the BBC World Service. Each podcast focuses on one of 50 inventions, ideas and innovations which have helped shape the economic world.
Learn about a huge range of innovations from baby formula to Ikea's Billy bookcase to M-Pesa and beyond. A great series and some insightful learnings. Happy listening!
