Though "GIF" stands for "graphics interchange format," its correct pronunciation is "Jif," like the popular peanut butter brand. A GIF is a file type introduced in the late 1980s that uses data compression to reduce the file size. GIF images are much lower in quality than JPEG images and support far fewer color options. For the most part, GIFs are used for simple images and animated graphics that run on a loop. They are the perfect distraction on mobile devices because they load quickly and can be viewed easily on small screens. Now, many of these GIFs go viral on social media websites, replaying short clips of Hollywood comedies and adding to the onslaught of cute, funny cat media.
