The G in PNG and JPG


I had a series of shower thoughts this morning, in the shower no less. Or would it be no fewer, given I have a known quantity of showers?

  • PNG and JPG are both graphics formats with abbreviations ending with G, but for entirely different reasons.

  • GIF begins with G, but for the same reason PNG ends with G. And not the same reason GNU begins with G, which is a recursive acronym for something else, which it itself isn’t the same as the G in PNG.

  • Some people pronounce PNG as a vaguely network-sounding acronym, others just spell out the letters. I do the latter.

  • And then you have BMP, which refers to graphics as Picture instead; and TIFF, which now that I think about it I can’t remember what it stands for.
