Few programmers ever work on something that'll still be in use 15 years later. Just have a look at http://en.wikipedia.org/wiki/Category:1995_software http://en.wikipedia.org/wiki/Category:1995_software (which isn't complete, obviously) - I don't think that even MS Office still contains much of what was in it in the '95 edition.
