Yea, I think the DJIA originated in 1895. The only company that was on
the original DJIA, and still is, is GE. All the others have went away.

Interestingly, the duration that a company is listed on one of the US
exchanges seems to follow an entropic paradigm. Of the many 10's of
thousands of companies listed on the US exchanges in the 20'th
century, half were listed less than 22 years, half more. And the
distribution seems to fit a 1 / sqrt (t) scenario.
