DJIA Remix - Component tenure

Dow Jones announced two new Dow components today, the first change to this major market index since 2004. Honeywell and Altria are out while Chevron and BofA are in.  The change will take effect next week. 

The Dow Jones Industrial Average originally was an index of 12 "smokestack" companies and made its debut in 1896. Since then it has expanded to have 30 companies. Of today's members, only General Electric was on the original list. It was replaced by US Rubber in 1898 and then added back in 1907 to replace Tennessee Coal and Iron.

Here are the current components sorted by seniority:
