From an online bookstore to cloud and AI infrastructure: how Amazon kept expanding
Amazon began with a question that sounded strange in 1994: what could an online store do that a physical shop could not?
Jeff Bezos left a New York investment firm that year to build an internet business. His first idea was an online bookstore capable of offering a catalogue far larger than any physical bookstore could stock.
Amazon opened to customers in 1995. Within its first weeks, the company was already shipping books across the United States and internationally. What followed was a pattern that would define Amazon for decades: enter one business, build infrastructure to solve its own problems, then turn that infrastructure into another business.
As of 18 September 2026, Andy Jassy is Amazon’s president and chief executive, while Bezos serves as executive chair. Amazon now spans online and physical retail, logistics, cloud computing, streaming, advertising, devices, satellites, AI infrastructure and semiconductor design.
Jeff Bezos started with books because the internet removed shelf space
Bezos has described the original concept as an online bookstore capable of offering millions of titles — a range that would be economically impossible for one physical location.
He founded Amazon in 1994 and moved to the Seattle area. The website opened in July 1995.
An early Amazon press release described more than one million titles and orders arriving from 45 countries in the first four weeks.
Books were therefore less important as an end point than as a starting category suited to the web. A physical shop could only stock a limited number of titles, while an online catalogue could expose customers to a much wider selection.
The IPO gave Amazon capital to expand beyond books
Amazon listed on the Nasdaq in 1997.
The company quickly expanded into music, video and other retail categories. It also developed features that became normal parts of online commerce, including customer reviews, personalised recommendations and third-party selling.
Marketplace was especially important because Amazon no longer needed to own every item sold through its website. Independent merchants could list products while Amazon provided the customer traffic, payments and increasingly the logistics.
Prime changed the relationship from transaction to membership
Amazon launched Prime in 2005 around fast shipping for a recurring membership fee.
The model changed customer behaviour. Instead of reconsidering shipping costs with every order, members had an incentive to make Amazon a default shopping destination.
Prime later expanded into video, music and other services, making it a broader ecosystem rather than only a delivery programme.
The recurring membership also gave Amazon another way to deepen customer loyalty beyond individual product prices.
AWS turned Amazon’s internal infrastructure problem into a new industry
Amazon Web Services became one of the most consequential extensions of the company.
As Amazon’s retail site grew, its engineers needed scalable computing infrastructure. The company realised that other organisations faced similar problems and could consume computing resources as services instead of buying and operating all their own servers.
Amazon launched AWS services in the mid-2000s. S3 provided object storage and EC2 provided on-demand compute capacity.
Those services helped popularise infrastructure-as-a-service cloud computing. Start-ups could rent computing by the hour, while large organisations could move workloads into Amazon data centres rather than treating IT infrastructure as a fixed capital purchase.
Andy Jassy built AWS before becoming Amazon CEO
Andy Jassy joined Amazon in 1997 and played a central role in creating AWS.
He later became chief executive of AWS and led the business as it grew into one of Amazon’s most important operations.
When Bezos stepped down as Amazon CEO in 2021, Jassy became president and chief executive of the parent company. Bezos moved to executive chair.
The transition was notable because the new CEO came from the cloud business rather than retail, reflecting how important AWS had become to Amazon’s economics and strategy.
Kindle turned Amazon from bookseller into device maker
Amazon introduced Kindle in 2007.
The e-reader combined hardware with a digital bookstore and wireless delivery. Instead of shipping a physical book from a warehouse, Amazon could deliver an electronic title to a customer in seconds.
Kindle demonstrated another recurring company strategy: control more of the customer experience by building the device as well as the service.
Amazon later expanded its hardware portfolio with Fire devices, Echo speakers and Alexa.
Alexa pushed Amazon into the home
The Echo speaker and Alexa voice service moved Amazon into ambient computing.
Users could ask questions, control compatible smart-home devices, play music and access Amazon services without opening a browser or phone app.
Alexa also became another example of Amazon building a platform and encouraging third-party developers and device makers to extend it.
Logistics became a technology business in its own right
Fast delivery required Amazon to build fulfilment centres, sortation systems, delivery networks, robotics and increasingly sophisticated software.
That infrastructure gradually reduced the company’s dependence on traditional parcel carriers for many deliveries.
Warehouses became large-scale automation environments in which robots, computer vision, forecasting and routing software affect how products move from inventory to a customer’s door.
Amazon’s retail story is therefore also a story about physical infrastructure and industrial technology.
Advertising grew out of Amazon’s shopping data
Amazon also built a large advertising business around product discovery and purchase intent.
Brands can advertise products to customers already searching or browsing inside Amazon’s stores, while the company also sells advertising across streaming and other services.
By 2026, advertising had become a major business alongside Stores and AWS.
AI and custom chips became another infrastructure layer
Amazon’s AI strategy is closely tied to AWS.
The company has developed custom processors including Graviton for general cloud workloads and specialised Trainium and Inferentia chips for machine learning.
Amazon Bedrock provides access to foundation models and generative-AI services through AWS.
In its 2026 results, Amazon said both its AI business and chips business had passed annual revenue run rates of US$25 billion. The company was also planning very large capital expenditure focused heavily on infrastructure.
This is consistent with Amazon’s history: infrastructure originally built to solve an internal or customer problem becomes a platform sold at enormous scale.
Amazon has become several companies sharing one infrastructure philosophy
It is difficult to describe modern Amazon with one industry label.
Retail brings customers and merchants. Prime connects membership, delivery and entertainment. AWS sells computing infrastructure. Advertising monetises customer attention. Devices extend Amazon into homes, while logistics and robotics support physical commerce.
The common thread is scale and reusable infrastructure.
How Amazon became what it is today
Amazon’s biggest expansions rarely abandoned the previous business. They accumulated on top of it.
Books led to general retail. Retail led to Marketplace and fulfilment infrastructure. Infrastructure expertise helped produce AWS. Digital content helped justify Kindle and Prime Video. Large data-centre investment created the foundation for AI services and custom chips.
Bezos established the company’s culture around experimentation and long-term investment. Jassy now leads a much broader organisation in which cloud and AI are as strategically important as the online store that created Amazon’s name.
