Fortune 1000 is a reference to a list maintained by the American business magazine Fortune. The list is of the 1000 largest American companies, ranked on revenues alone. Eligible companies are any for which revenues are publicly available (which is a larger universe than "public companies," as the term is commonly understood, meaning "companies whose common stock trades on a stock market"). The list draws the attention of business readers seeking to learn the influential players in the American economy and prospective sales targets, as these companies tend to have large budgets and staff needs.
