Fortune Global 500  The "Fortune" Global 500, also known as Global 500, is an annual ranking of the top 500 corporations worldwide as measured by revenue. The list is compiled and published annually by "Fortune" magazine. Until 1989, it listed only non-United States industrial corporations under the title "International 500" while the "Fortune" 500 contained and still contains exclusively United States corporations. In 1990, United States companies were added to compile a truly global list of top industrial corporations as ranked by sales. Since 1995, the list has had its current form, listing also top financial corporations and service providers by revenue. Several inconsistencies exist in "Fortune" ranking of cities with the most "Fortune" 500 headquarters. On June 3, 2011, the "Atlanta Business Chronicle" stated examples of "Fortune" including regional headquarters for some cities, excluding regional headquarters for other cities and in some cases excluding headquarters that are physically located inside a city limit. Since 2001, there has been a significant change in the geographical distribution of the companies in the Global 500 rankings. The number of North American-based companies decreased from 215 in 2001 to 143 in 2017 and the contribution of Asian-based companies increased rapidly from 116 in 2001 to 197 in 2017. Most of this growth is accounted for by the rapid increase in the number of Chinese Global 500 companies, of which there were 109 by 2017, increasing from only 10 in 2001. The share of European-based companies also declined, from 158 to 143, over the same period.
