Here's a cute scuba diving scene from A Pup Named Scooby-Doo. SCUBA, an acronym for self-contained underwater breathing apparatus, was coined only 17 years before Scooby-Doo debuted. There's a lot of scuba diving in the old episodes because scuba diving was seen as a hip, new thing. When I was a kid, some people were still writing it, "SCUBA." From 1943 to 1952, it was called an aqua-lung. Before 1943, people used the standard diving dress. | Zac Hanscom
