As of June 15, 2017, the GIF is 30 years old.

On that same date in 1987, the most often-used image file extension was created by a team of CompuServe developers looking for a way to compress photos with minimal data loss.

Three decades later, the resulting flexible file format for lower-resolution pictures has given us babies that dance… reality stars that cry… and pretty much everything in between.

In honor of this anniversary, we present below the most memorable GIFs in World Wide Web history. Click around and enjoy!
