Picky, picky, picky.
All right, so almost nobody addressed the problem. The point was that
people were aware as early as the mid 1970's that the two digit years
that had been widely used to save space on 80 column punched cards and
never changed to four digit years were going to be a problem. It wasn't
so much the old data as the programs that were written to handle two
digit years and just assumed that the years involved were all 19xx.
New software generally used four digit years but there was an awful lot
of legacy stuff that had been around since the 1960's and 70's that
needed to be fixed. Nobody wanted to spend money fixing something that
wouldn't break for twenty-five years, or twenty years, or ten or five.
The effort to test and clean up all the application software didn't
really get under way until around 1998 or, in many cases, 1999.
