Amazon.com(Amazon.com, Seattle, WA, www.amazon.com) The largest online shopping site in the U.S. Founded by Jeff Bezos in 1994, within four years, Amazon had more than four million customers. Today, more than 100 million visitors access the site each month.
From a Bookstore to Nearly Everything
Amazon started out as an online bookstore, constantly making news with its product volume. In the late 1990s, after adding CDs, videos, DVDs and games, Amazon offered more than four million titles. It continued to add new lines of business including toys, consumer electronics, software, power tools, home improvement products, online auctions and cloud computing services, the latter a significant profit center for the company (see Amazon Web Services). By opening up its e-commerce platform to non-Amazon vendors in 2000, nearly every legal product that can be shipped is available on Amazon's site. See Fulfillment by Amazon and one-click ordering.
Amazon Prime Membership
In 2005, Amazon Prime was introduced as an annual subscription. Prime offers free one-day and two-day shipping on most products Amazon stocks in its warehouses. Prime membership increasingly offers other benefits, including unlimited video and music streaming, photo storage and e-book lending (Prime Video, Amazon Music, Amazon Photos and Kindle eBooks). See AmazonFresh and Amazon Go.
Amazon's Own Products
In the late 2000s, the company began to offer Amazon-branded items, including e-book readers, tablets, smartphones, cables and other devices (see Kindle, Kindle Fire, Fire Phone, Amazon Echo and Amazon Dash).
prime numberAn integer greater than 1 that is not evenly divisible by any number other than itself, and, of course, 1. Prime numbers are considered a fundamental building block of numbers, especially number theory, a branch of mathematics.
The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Except for 2, all primes are odd numbers. As the numbers get higher, prime numbers tend to be found in pairs that are close together; for example, 29,669 and 29,671 are primes. The largest prime number thus far, which contains more than 65,000 digits, was discovered in 1986.
