The Wall Street Journal has created a data visualization illustrating how the makeup of the Dow Jones Industrial Average has changed since its debut in May 1896. The visualization highlights major changes in the stocks that make up the Dow, such as when a large number of the stocks were replaced during the Great Depression as companies folded and when “new economy” stocks, such as Microsoft and Intel, were added in 1999. The visualization color-codes each stock by industry to make it easy for users to compare the Dow’s makeup over time.
