Barnes & Noble sued Amazon on May 12, 1997, alleging that Amazon's claim to be "the world's largest bookstore" was false because it "...isn't a bookstore at all. It's a book broker." The suit was later settled out of court and Amazon continued to make the same claim.[36] Walmart sued Amazon on October 16, 1998, alleging that Amazon had stolen Walmart's trade secrets by hiring former Walmart executives. Although this suit was also settled out of court, it caused Amazon to implement internal restrictions and the reassignment of the former Walmart executives.[36]

Shortly after the first Kindle launched, Amazon premiered its Kindle Direct Publishing platform to let authors self-publish and sell books on Amazon. Two years later, the company launched its own suite of professional imprints called Amazon Publishing. Amazon now oversees tens of millions of self-published works on its platform and nearly two dozen imprints. In 2017, Amazon had more than 83 percent of all US ebook sales.

In 2015, Amazon surpassed Walmart as the most valuable retailer in the United States by market capitalization.[11] Amazon is the third most valuable public company in the United States (behind Apple and Microsoft),[12] the largest Internet company by revenue in the world, and after Walmart, the second largest employer in the United States.[13] In 2017, Amazon acquired Whole Foods Market for $13.4 billion, which vastly increased Amazon's presence as a brick-and-mortar retailer.[14] The acquisition was interpreted by some as a direct attempt to challenge Walmart's traditional retail stores.[15]
The domain attracted at least 615 million visitors annually by 2008.[119] Amazon attracts over 130 million customers to its US website per month by the start of 2016.[120] The company has also invested heavily on a massive amount of server capacity for its website, especially to handle the excessive traffic during the December Christmas holiday season.[121]
Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians,[178] and former employees,[179][180] as well as the media and politicians. In 2011, it was publicized that at the Breinigsville, Pennsylvania warehouse, workers had to carry out work in 100 °F (38 °C) heat, resulting in employees becoming extremely uncomfortable and suffering from dehydration and collapse. Loading-bay doors were not opened to allow in fresh air, due to the company's concerns over theft.[181] Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees.[181] The company eventually installed air conditioning at the warehouse.[182]
Aside from creating the logo, A.J Khubani actually played a huge role in the advent of the infomercial as we know it today, which started with his Amber Vision sunglasses in 1987. More recently, his company sold the PedEgg, another As Seen On TV product which has sold 50 million units (in addition to other successful products like the As Seen On TV mop and the As Seen On TV hose). Anyone looking for the same level of success with their own product can pitch their idea to both Telebrands and As Seen On TV, Inc. although they only accept a few submissions each year.
