This episode follows the fortunes of the ultimate online retail success story - a business that was born in a garage 20 years ago and grew into a 100 billion pound global giant. Along the way, the Amazon phenomenon has inspired, shaped - and sometimes squeezed - the rest of the retail sector, while revolutionising attitudes to online business and transforming the way people shop. The story of the growing use of Amazon is the story of the internet age.

Time and again, founder Jeff Bezos has moved the goalposts for many industries. Publishers, retailers and even the French minister of culture criticise Amazon's practices and bemoan its sheer size, but Amazon defends its record for providing customers with choice and competitive prices. Furthermore, Bezos' confidence in his mantra of 'start with the customer and work backwards' is already taking Amazon into new sectors - groceries, ebooks, film production, and cloud computing services.
