From 1950 to 1980, the digest-sized Galaxy Science Fiction magazine became well-known for its focus on social issues rather than technology, which became its own sub-genre (New Wave) within the larger speculative fiction scene. Author Frederik Pohl helped the original editor, H.L. Gold, craft the production from the late 1950's, eventually taking over officially in 1961. There were a string of editors after the magazine was sold in 1969, and the quality never quite recovered barring a couple of solid stints by talented editors like James Baen, who went on to found sf imprint, Baen Books. The final issue came out in 1980; a semi-professional publication came out in 1994 under the same name but only lasted eight bimonthly issues.
