Elon Musk: Money, memes and Mars

Elon Musk’s extraordinary rise, from a troubled childhood in apartheid-era South Africa to becoming the first person to amass half a trillion dollars.

BBC business editor Simon Jack and journalist Zing Tsjeng chart Elon Musk's journey to becoming a multi-billionaire entrepreneur: from tech giant PayPal, to revolutionising electric cars at Tesla, and launching rockets at SpaceX. But becoming the richest person in the world comes with plenty of boardroom drama and controversy.

Good Bad Billionaire is the podcast that explores the lives of the super-rich and famous, tracking their wealth, philanthropy, business ethics and success. There are leaders who made their money in Silicon Valley, on Wall Street and in high street fashion. From iconic celebrities and CEOs to titans of technology, the podcast unravels tales of fortune, power, economics, ambition and moral responsibility. Simon and Zing put their subjects to the test with a playful, totally unscientific scorecard — then hand the verdict over to you: are they good, bad, or simply billionaires?

We're taking a break over the next few weeks but we'll be back in the New Year with a host of new billionaires.
