Jeff Bezos, an American entrepreneur, founded Amazon in 1994 as an online marketplace for books, which has since expanded to become the number one online retail seller in the United States. In 2021, Amazon surpassed Walmart as the world‘s largest retailer, largely due to its paid subscription plan, Amazon Prime, which has over 200 million subscribers worldwide. With an annual revenue of $469.822 billion and 1,608,000 employees, Amazon is the second largest private employer in the United States.
