Jeff Bezos filed the paperwork to create the e-commerce retailing giant Amazon 25 years ago. His genius was to recognise the potential of the internet long before others. Amazon is known for its disruption of well-established industries through technological innovation and mass scale. But its dominance is problematic. Its growth has displaced traditional retail jobs. And it's faced criticism over worker conditions at its warehouses. Today, 25 years on from when it started, Amazon is one of the most valuable public companies in the world, with Mr Bezos now the world's richest man, thanks to his invention.What started as an online book retailer has become a global giant, with membership subscriptions, physical stores, groceries for sale, its own smart devices and a delivery system which can get things to customers in just an hour.
