It's Pronounced GIF

The Facts

GIF stands for Graphics Interchange Format. The format was created by Steve Wilhite at CompuServe in 1987. In 2013, Wilhite accepted a Webby Award and used the platform to definitively state that it is pronounced "JIF," like the peanut butter, and that it always has been. The internet responded by explaining to the man who invented the format that he was pronouncing his own invention incorrectly.

This is a nearly perfect encapsulation of how technical debates work.
