PPM at a glance
PPM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
FITS at a glance
FITS
FITS became a durable scientific standard because observatories, spacecraft, and analysis tools needed a stable interchange format that outlived individual instruments and software stacks.
