Amazon was incorporated in 1994, in the state of Washington. In July 1995, the company began service and sold its first book on Amazon.com — Douglas Hofstadter's Fluid Concepts and Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought. In 1996, it was reincorporated in Delaware. Amazon issued its initial public offering of stock on May 15, 1997, trading under the NASDAQ stock exchange symbol AMZN, at a price of US$18.00 per share ($1.50 after three stock splits in the late 1990s). Amazon's initial business plan was unusual. The company did not expect a profit for four to five years. Its "slow" growth provoked stockholder complaints that the company was not reaching profitability fast enough. When the dot-com bubble burst, and many e-companies went out of business, Amazon persevered, and finally turned its first profit in the fourth quarter of 2001: $5 million or 1¢ per share, on revenues of more than $1 billion. The profit, although it was modest, served to demonstrate that the business model could be profitable. In 1999, Time magazine named Bezos the Person of the Year, recognizing the company's success in popularizing online shopping. Barnes and Noble filed a lawsuit on 12 May 1997, alleging that Amazon's claim to be "the world's largest bookstore" was false. Barnes and Noble asserted, "[It] isn't a bookstore at all. It's a book broker." The suit was later settled out of court. Amazon continued to call itself "the world's largest bookstore."[12] Walmart subsequently filed suit on 16 October 1998, alleging that Amazon had stolen trade secrets by hiring former Walmart
