The Fortune 500 is an annual list compiled and published by Fortune magazine that ranks 500 of the largest United States corporations by total revenue for their respective fiscal years.[1] The list includes publicly held companies, along with privately held companies for which revenues are publicly available. The concept of the Fortune 500 was created by Edgar P. Smith, a Fortune editor, and the first list was published in 1955.[2][3] The Fortune 500 is more commonly used than its subset Fortune 100 or superset Fortune 1000.[4]
