Fortune 500

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. 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. The Fortune 500 is more commonly used than its subset Fortune 100 or superset Fortune 1000.

History
The Fortune 500, created by Edgar P. Smith, was first published in 1955. The original top ten companies were General Motors, Jersey Standard, U.S. Steel, General Electric, Esmark, Chrysler, Armour, Gulf Oil, Mobil, and DuPont.

Methodology
The original Fortune 500 was limited to companies whose revenues were derived from manufacturing, mining, and energy exploration. At the same time, Fortune published companion "Fortune 50" lists of the 50 largest commercial banks (ranked by assets), utilities (ranked by assets), life insurance companies (ranked by assets), retailers (ranked by gross revenues) and transportation companies (ranked by revenues). Fortune magazine changed its methodology in 1994 to include service companies. With the change came 291 new entrants to the famous list including three in the Top 10.

Influence
As of 2020, the Fortune 500 companies represent approximately two-thirds of the United States' gross domestic product with approximately $14.2 trillion in revenue, $1.2 trillion in profits, and $20.4 trillion in total market value. These revenue figures also account for approximately 18% of the gross world product. The companies collectively employ a total of 29.2 million people worldwide, or nearly 0.4% of the world's total population.
