Why I bother, I don’t know, but I must rebut, once and for all, the claim that the creator of the format determines the pronunciation of the acronym. In this case, the creator was neither a linguist nor a logician, nor remotely acquainted with English language conventions. More than likely, he was one of the Internet’s earliest trolls and cannot be relied upon for any useful information other than that which relates to his chosen field of endeavor, namely, engineering/programming. Q.E.D., he should be ignored regarding this issue. Upshot: GIF should logically be pronounced according to the words comprising its expanded meaning: Graphic Interchange Format. In other words, use a hard G, not a soft one. Let us now move on to important things.
