Henry Ford may not have invented the car, or even the assembly line, but he perfected them. His Model T – nicknamed “Tin Lizzie” – made cars affordable for the average worker, not just the rich. He was a master tinkerer, inventor and even introduced the five-day 40-hour work week – better than the six-day grind that was the norm at the time.

But his legacy is a complicated one. He increased wages but crushed unions. Plus he used his popularity to spread antisemitic conspiracy theories. In 1938, Germany’s Nazi regime even gave him a medal for it. BBC business editor Simon Jack and journalist Zing Tsjeng tell the story of the man whose influence helped push America from farm to factory, shaping roads, suburbs, motels, and malls.

John D Rockefeller built his fortune refining oil and founding Standard Oil. A pioneer of the U.S. business trust, he helped shape the structure of the modern corporation. His influence lives on in companies like Chevron, ExxonMobil, and ConocoPhillips, and in institutions like the Rockefeller Foundation. But not everyone saw him as a visionary. President Theodore Roosevelt branded the Rockefeller family a “malefactor of great wealth,” and Rockefeller’s monopoly helped spark America’s first antitrust laws. To some, he was a ruthless robber baron; to others, a generous philanthropist who gave away over $500 million. BBC business editor Simon Jack and journalist Zing Tsjeng unpack the contradictions of Rockefeller’s empire. Can great giving make up for great power?

LeBron James was selling out basketball arenas while still in high school. At just 18, he said he was offered a $10 million cheque from Reebok - on the spot - if he agreed not to meet any other brands. It was a life-changing sum for a teenager living with his mum in the projects.
