Investors ultimately haven’t been happy to see the news that General Electric Co. is considering off-loading its century-old appliance unit, which is as much responsible for the company’s reputation as the ubiquitous light bulbs the conglomerate sells.

Perhaps investors believe GE isn’t doing quite enough to prune its holdings after a surprisingly poor first-quarter earnings release. On the other hand, maybe jettisoning this unit affects those who have a flair for nostalgia. Shares of late were down 0.9%.

After all, GE founded this unit in 1907, and counts the refrigerator and room air-conditioner among the innovations it introduced to the American public. Those things didn’t exist in 1907, but the Dow Jones Industrial Average did, and of the companies that were members of the average at the time, only GE remains.

In fact, GE, one of the original members of the average in 1896, was removed, but reinstated in 1907 — making its tenure in the Dow as long as the history of its appliance division. Most of the other components of the time have been absorbed or disbanded, although U.S. Steel is still operating, though it was excised from the Dow 30 in 1991.
