It was initially published by Scion Press, with control passing to a successor company, Scion Distributors, after Scion went bankrupt in early 1954.  At the end of 1954, as part payment for a debt, Scion Distributors handed control of the magazine to Dragon Press, who continued it for another twelve issues.  E.C. Tubb and John Russell Fearn were regular contributors, and Kenneth Bulmer also published several stories in the magazine.  Barrington Bayley's first published story, "Combat's End", appeared in May 1954.  The editor was initially Alistair Paterson, but after seven issues Fearn took the helm: "Vargo Statten" was one of Fearn's aliases, and the magazine's title had been chosen because of his popularity.  Neither Paterson nor Fearn had enough of a budget to attract good quality submissions, and a printing strike in 1956 brought an end to the magazine's life.
