Fascinating. So PD in PDF came from Postscript distiller? All these years... I did not know that.

  Sounds like an unanswerable question; it would be surprising if anyone reliably remembered earlier expansions for the initialism. Distiller remains an Adobe product.

    The official name when PDF was launched as "Portable Document Format". I have no idea if that was a "backronym" for some internal project name.

      Exactly.
