Founded by Jeff Bezos in 1994 as an online bookseller operating out of a garage in Bellevue, Washington, Amazon was built on the premise that the internet could support a retail catalogue far broader than any physical store. The original thesis was about selection and convenience; the infrastructure required to deliver that thesis became, over time, a business in its own right.

The launch of Amazon Web Services in 2006 is the clearest inflection point in the company's history. What began as an internal effort to standardise Amazon's own engineering infrastructure was commercialised into a public cloud platform. AWS now operates as a distinct reporting segment and has consistently generated the majority of Amazon's operating profit, even as the retail division commands the greater share of revenue. The Prime membership programme, introduced in 2005, is the other structural move worth noting: it reframed retail competition around loyalty and logistics speed rather than price alone.

Today Amazon operates across consumer e-commerce, third-party marketplace services, fulfilment and logistics, cloud infrastructure, digital advertising, and devices. AWS competes directly with Microsoft Azure and Google Cloud for enterprise and scale-up infrastructure spend. The advertising business has grown into a significant revenue line, monetising the purchase-intent data generated by the retail platform.

For operators, Amazon is worth watching on two fronts. First, AWS sets the baseline expectations for cloud pricing, reliability, and service breadth that every infrastructure decision gets benchmarked against. Second, Amazon's marketplace model, in which the company simultaneously acts as retailer, platform, and logistics provider to third-party sellers, remains one of the most studied and contested structures in platform economics. How regulators in the UK and EU respond to that model will shape the rules of engagement for any business building on or competing with large platform operators.
