For a lot of people in non-technical professions it might actually be Windows XP. That is, of course, if we're putting aside some of the basic UNIX tools that probably haven't changed since the 1970s—which I think is fair.

I believe that honour goes to dc (if you're in linux, you can still use dc).

  In Linux, "dc" will be GNU dc, which would have been written late 80s or early 90s, like most other GNU utilities. And it would have been maintained/modified over the years. (A better example would be the bsdgames collection. It's a lot older and has barely been touched over the years.)

  Nice find! Man page footer on current OS X says 1997-03-25. I looked at some other man pages from ls, cat, tar and the like and the oldest that I found was rm, from January 28, 1999. UPDATE! rmdir's man page is from May 31, 1993! Though I'm sure the actual code was updated since then.
