A blocked vacuum cleaner led to a billion-dollar idea for British inventor Sir James Dyson. After studying art, then reinventing the wheelbarrow, Dyson struck gold with his iconic bagless vacuum, but only after years of effort.

BBC business editor Simon Jack and journalist Zing Tsjeng take us back to the entrepreneur’s youth in post-War Norfolk and discover a childhood marked by tragedy. From his years as a jobless inventor, frustrated by existing technology, Dyson’s story is one of innovation, ambition and risk, with legal battles once leaving him on the verge of bankruptcy. But the engineer’s determination and obsession with perfection paid off, with his company now worth billions. The Dyson name has become synonymous not only with vacuum cleaners, but also fans, heaters, hand dryers and hairdryers. He’s even started his own engineering university. Simon and Zing look back at Dyson’s success story and find out how he made his fortune, before deciding if they think he’s good, bad, or just another billionaire.

What do Airbnb, Facebook, Spotify, and LinkedIn all have in common? Peter Thiel. They made his fortune, but he’s since rejected Silicon Valley for being too "woke".
