HAD 1 JOB YEARS AGO THAT REQUIRED  POLAROID SLIDES.

NEVER USED IT SINCE.

WHEN I WAS IN COLLEGE IN THE LATE 60s AND 70s I  REMEMBER BEING RECRUITED IN A MARKET SURVEY,  TURNED OUT IT WAS FOR  POLAROID INSTANT FILM.  WE WEREN'T TOLD OF COURSE THAT IT WAS POLAROID.   MOST OF THE GROUP HATED IT.  I DID ALSO BUT THEIR FILM FOR GRAPHICS WITH A  BLUE BASE WAS QUITE NICE.  THAT IS THE ONE I USED FOR THE JOB.
