Amazon is ramping up in sectors with strong growth prospects that tie to its e-commerce roots.
Retail
The company's core. Its online business amounts to 62 percent of revenue. Its cut from third-party sellers is another 18 percent.
Media
An add-on to its Prime suite of services for consumers. Only Netflix will spend more on movie and TV production this year.
Web services
The data warehouse and cloud services unit is Amazon's fastest-growing business and now accounts for 11 percent of revenue.
Logistics
It loses money on shipping and is trying to fix that with its own trucks, planes and ships. This is where the drones are, too.
