In 1994, soon after Jeff Bezos incorporated what would become Amazon, the entrepreneur briefly contemplated changing the company’s name. The nascent firm had been dubbed “Cadabra,” but Bezos wanted a less playful, more accurate alternative: “Relentless.” (Relentless.com redirects to Amazon.com to this day.) Twenty-four years later, perhaps no adjective better describes Bezos’ empire than the name he once wanted to give it.

The company is known as the “everything store,” but in its dogged pursuit of growth, Amazon has come to dominate more than just ecommerce. It’s now the largest provider of cloud computing services and a maker of home security systems. Amazon is a fashion designer, advertising business, television and movie producer, book publisher, and the owner of a sprawling platform for crowdsourced micro-labor tasks. The company now occupies roughly as much space worldwide as 38 Pentagons. It has grown so large that Amazon’s many subsidiaries are difficult to track—so we catalogued them all for you. This is our exhaustive map of the Kingdom of Amazon.

You might be wondering, why Amazon? After all, other tech firms, including Google and Facebook, have also expanded outside their core businesses in recent years. But few other companies can claim leadership in sectors as disparate as videogame streaming, online fabric sales, and facial recognition. Amazon also employs far more people than its competitors. Roughly 613,000 people work at Amazon, more than twice as many as work at Alphabet (94,000), Facebook (33,000), and Microsoft (135,000) combined. Most of those workers labor in one of Amazon’s more than 100 North American logistics centers, or at one of more than 450 Whole Foods stores.

Amazon employees are paid far less than other tech workers. In its annual filing with the Securities and Exchange Commission in February, Amazon reported its median worker earned $28,446 in 2017 (it says that number jumps to $34,123 for full-time US workers). Facebook’s median salary in 2017, by contrast, was more than $240,000.

A bit of context: It helps to know how Amazon makes money. While its retail business is the most visible to consumers, the cloud computing arm, Amazon Web Services, is the cash cow. AWS has significantly higher profit margins than other parts of the company. In the third quarter, Amazon generated $3.7 billion in operating income (before taxes). More than half of the total, $2.1 billon, came from AWS, on just 12 percent of Amazon’s total revenue. Amazon can use its cloud cash to subsidize the goods it ships to customers, helping to undercut retail competitors who don’t have similar adjunct revenue streams.

Books

Amazon began as an online bookseller in 1994, and although it quickly expanded into other ventures, it still owns and operates multiple publishers and online bookselling subsidiaries. Nowadays, most of these fall under the umbrella of Amazon Publishing, which is both a publisher and the owner of imprints for specific genres, languages and locales.

Amazon imprint Thomas & Mercer publishes mysteries, thrillers, and true crime novels; Little A handles literary fiction and nonfiction; AmazonCrossing is responsible for translated texts; 47North does science fiction and fantasy; Skyscape is for teen and young adult books; there’s Two Lions for children’s books; Jet City Comics for, well, comics; Montlake Romance handles—you guessed it—romance; Waterfall Press publishes Christian fiction; Grand Harbor Press is responsible for a category Amazon describes only as “inspirational;” Lake Union Publishing handles "book club fiction;" Amazon Original Stories publishes short stories and nonfiction 1; AmazonEncore is for "rediscovered works;" and TOPPLE Books spotlights works selected by Jill Soloway. Amazon also has acquired Avalon Books, The Book Depository, BookFinder, Westland Books, and AbeBooks.

In 2005, Amazon acquired BookSurge, an on-demand self-publishing service, and CustomFlix, an on-demand video publishing service, which was later renamed CreateSpace. Two years later it bought independent audiobook producer, Brilliance Audio, and launched its own e-book publisher, Kindle Direct Publishing, concurrently with the first Amazon Kindle e-reader. Soon after, the company paid $300 million to acquire audiobook seller Audible. It also owns ACX, an audiobook publishing company.
