How did the richest people on the planet make their billions? Find out with the Good Bad Billionaire podcast, and then have your say about whether you think they are good, bad or just another billionaire. Our brand new season starts with Beyoncé.

Latest episodes: Toto Wolff, Elizabeth Holmes and Elon Musk.

In each episode of Good Bad Billionaire, BBC Business Editor Simon Jack and journalist and author Zing Tsjeng analyse the lives of the super-rich, and try to understand what motivates billionaires like Kim Kardashian, Tyler Perry and Oprah Winfrey.

From singing superstar Beyoncé, to footballing legend Cristiano Ronaldo, Simon and Zing rate their wealth, power, legacy and associated controversies, putting them to the test with a playful, totally unscientific scorecard. Then they hand the verdict over to you: are they good, bad, or simply billionaires? Get in touch by email and let us know what you think! The contact details are at the end of these show notes.

Ever wondered how Taylor Swift went from country singer to money-spinner? How tennis ace Roger Federer turned sporting prowess into amazing business opportunities? Or how Mr Beast and Khaby Lame became some of the wealthiest people on the planet by posting on YouTube and TikTok? Trawl through the archives to find out how Selena Gomez went from a child Disney star to a mega-magnate of makeup, and how Martha Stewart, the “original lifestyle influencer”, became one of the most successful women in business.

We explore the life of British inventor Sir James Dyson, and learn about some of the big names behind Snapchat, Minecraft, Marvel, ChatGPT, Google and Amazon, which shape the world we live in today.

In a special season, we have also told the stories of the pioneers who helped build the United States of America: the world’s first billionaire John D Rockefeller, motor magnate Henry Ford, the aviator and filmmaker Howard Hughes, Walmart founder Sam Walton, and Hetty Green - once dubbed “The Witch of Wall Street”.

It's not just how billionaires made their money; it's what they did with it next.
