For the first time in history, Amazon has cracked the top 10 of the Fortune 500 list, alongside such behemoths as Apple, Berkshire Hathaway, Exxon Mobil and, of course, Walmart. With revenue of $177.87 billion, Amazon placed eighth on this year's list of America's largest companies, which was released on Monday. That's up four spots from its rank last year as No. 12. The online retailer bumped Fortune 500 veteran General Motors down to 10th place and Ford Motor out of the top tier altogether.

The online retailer made its debut at No. 492 on the Fortune 500 back in 2002, the same year its biggest competitor Walmart first landed in the No. 1 spot. Amazon has since quickly gained on, and nearly caught up with, Walmart.
