Business history

Learning about the history of businesses and industries can help you become a better investor, spotting red flags and green flags in the companies around you. Here are some great podcasts that like to look back:

NPR's How I Built This: This podcast features talks with those who have built various businesses. As an example, an episode I recently listened to and found fascinating and suspenseful covered the birth of Airbnb: "A chance encounter with a stranger gave Joe Gebbia an idea to help pay his rent. That idea grew into a company that now has more rooms than the biggest hotel chain in the world."

Business Wars: This podcast typically devotes several episodes to taking a close look at a big business rivalry, such as FedEx vs. United Parcel Service, Uber Technologies vs. Lyft, and Amazon.com vs. Walmart. Other wars covered include those involving diamonds and dating apps, to name a few.

Brought to You By...: This podcast delves into the surprising stories behind many familiar companies. One episode, for example, looked at how a dried vegetable and fish shop in South Korea became the juggernaut Samsung, while another examined the essential oils industry and its questionable origins.

Desperate Acts of Capitalism: Describing itself as "a podcast about rich idiots with bad ideas," this series delves into different businesses each week, often focusing on amusingly problematic ones. Consider this description of a recent episode: "A website designed to help you have an illicit marital affair that requires your personal information and a substantial fee to delete your account. What could possibly go wrong?"

Big and small ideas

Here are some great podcasts about ideas and issues concerning businesses:

HBR Idea Cast: This Harvard Business Review podcast describes itself as a "weekly podcast featuring the leading thinkers in business and management," such as Harvard professors, CEOs, and others with insights into aspects of business, including supply chains, marketing, diversity, competition, and more.

Outside In: This podcast focuses on customer-centric companies and looks at how the world is changing and how companies are changing to adapt to it. Recent episodes looked at the cultural reinvention of Microsoft and Impossible Foods' mission to replace meat by 2035.

The Marketing Companion: This podcast tackles marketing, with an aim to entertain while informing. It features interviews with leaders from many companies, and episodes go beyond just marketing. A recent one, for example, addressed how adidas is redefining sports, retail, and marketing during the pandemic.

This is, of course, just the tip of the iceberg when it comes to podcasts about business. Spend a little time searching in your favorite podcast app for business topics that interest you, such as marketing or management, and you'll find a treasure trove of content.
