I cannot imagine anybody seriously using an 8 year old obsolete version of anything and not being in the tiniest of minorities.
FORTRAN 77. That's all I have to say.
Well, I'll say a tiny bit more: YES, people do still use FORTRAN. YES, there are newer versions than the (19)77 version. HOWEVER, FORTRAN 77 is still in a great deal of use. Probably the majority of FORTRAN code in use today is FORTRAN 77. Certainly not a small minority.
Oh, and just because I like to point it out: FORTRAN is the last major language, before Python, to incorporate significant leading whitespace as a "feature" of the language. :-P
