A terrific explanation of the history of Dow, and the significance of the changes, courtesy of Briefing.com:

Dow Jones announced today the first changes to the Dow Jones Industrial Average in five years. While the DJIA is still the most well known market index, these changes render the index less important and it puts the final nail in the coffin of traditional Dow Theory. Inclusion in the index will still be, as it always has been, a kind of "honorary" emblem of significance, but the index as a whole becomes less important because of this change.

History of the Dow

An extensive history of the Dow Jones averages is fascinating, but beyond the scope of this article.

Instead, we offer a brief summary of major events in the index in the following table.

Date Event Comment
1884 Charles Dow publishes first list of "Dow Stocks" 11 stocks (9 railroads) which he said should be the primary focus of investors.
1886 First Dow list published with a summation of prices 12 stocks – 10 were railroads
1896 Dow list split into two lists: Railroad Index and Industrial Index Railroad Index later became Transportation Index
1907 General Electric added Bumped Tennessee Coal & Iron
Longest lasting stock in the index
1916 American Telephone & Telegraph added Bumped today
October 1928 Industrial Average set to 30 stocks and a divisor introduced. Divisor attempts to compensate for stocks with larger prices unduly affect the overall average
October 1929 Utility Average Introduced Introduced same month as the great crash.
July 1930 Eastman Kodak Added Bumped today
July 1956 International Paper Added Bumped today

Changes In The Dow
