I was thinking about companies approaching 200 years old since I knew my point would be more difficult to make if I said 100 years (and because they had a launch window that comes up roughly once every 200 years, though I checked that out and it is 175 years). That said, you're right about my basically overlooking companies that weren't based in technology.

Exxon is a cute example though. At one point, they owned Zilog.
