A simple invoice from 1995 revealing Amazon's first-ever purchase, a book on artificial intelligence, has recently gone viral. The post, shared by Jon Erlichman on X, garnered attention from Amazon founder Jeff Bezos, who reshared it, and billionaire Elon Musk, who remarked on its significance. The internet reacted with humor and nostalgia, reflecting on how a niche curiosity transformed into a global supply chain. Founded by Bezos on July 5, 1994, Amazon began as an online bookstore operating from a garage in Bellevue, Washington. It quickly expanded beyond books, evolving into an 'everything store' with various subsidiaries, including Amazon Web Services and Zoox. Bezos has noted the explosive growth of web usage in the mid-90s, which allowed Amazon to offer a wider selection of books than traditional stores could manage. This seemingly modest first sale symbolizes the beginning of Amazon's journey to becoming a multifaceted e-commerce powerhouse.
