How does the subject of a leaked sex tape become a billionaire business mogul? Journalist Zing Tsjeng and BBC business editor Simon Jack find out how Kim Kardashian leveraged her fame and sold her privacy to earn billions, breaking the internet along the way.

They follow her money making schemes, from selling celebrities' clothes online and styling Paris Hilton, to multi-million dollar weddings and public family feuds. But they discover that Kim actually made her billions in a much more traditional way.

She's one of the most famous faces in the world, loved and loathed by millions. In the podcast that uncovers how the world's wealthiest people made their money and asks if they are good or bad for the planet, Simon and Zing judge Kim Kardashian.
