The McRib made its debut at McDonald’s in 1981, and while it initially attracted some attention, it wasn’t enough to keep it as a permanent fixture on the menu. But when the sandwich was taken away, many customers expressed disappointment and a desire for its return. This prompted McDonald’s to periodically bring the McRib back, but always for a limited time, over the next few decades. The sandwich’s temporary nature sparked a devoted following, so much so that a McRib locator was created to help fans find it.
