Did you know?

Remember way back when cameras used film? Back then, such devices were simply called cameras; they weren't specifically called film cameras until they needed to be distinguished from the digital cameras that came later. Similarly, the term desktop computer wasn't often used until laptops became prevalent. A lot of our common retronyms have come about due to technological advances: acoustic guitar emerged to contrast with electric guitar, and brick-and-mortar store came into use to distinguish traditional stores from online retailers. Retronym was coined by Frank Mankiewicz, an American journalist and former president of National Public Radio, and was first seen in print in 1980. Retronyms themselves are of course much older; British English, for example, is a retronym called into service when American English developed.
