In 1951, the genesis of recreational diving, there was only one dive magazine; "SKIN DIVER MAGAZINE; a magazine for spearfishermen and skin divers." (The word SCUBA was not in common usage for a number of years) This magazine was classified in the publishing industry as a sports publication.
After about ten years it was sold and a new editor was installed who discovered and almost single handed established the infant industry of dive travel. As other magazines came into being they followed the same blue print. Now almost all dive magazines are considered as travel magazines.
However, there are a few dive magazine that are still considered and identified as sports or specialty publications, but they are few in number and that number is rapidly dwindling, alto soon all dive magazines will possibly need to morph into travel publications to attract readers and their very survival.
