On May 6, 1991, the Walt Disney Company joined the Dow Jones Industrial Average (known as the Dow), a stock market index that tracks the value of 30 publicly owned companies from the United States. This inclusion was part of a revamp of the Dow, and was the first time an entertainment company had been added to the Dow since 1932; Paramount-Publix was briefly in the Dow from 1928 to 1932. Disney was added alongside J.P. Morgan and Caterpillar Inc., replacing Navistar International Corporation, USX Corporation, and Primerica Corporation.
