Howard Browne took over as editor of both "Amazing Stories" and "Fantastic Adventures" in 1950. Browne preferred fantasy to science fiction, and enjoyed editing "Fantastic Adventures", but when his plans for taking "Amazing" upmarket were derailed by the Korean War, he lost interest in both magazines for a while. He let William Hamling take responsibility for both titles, and the quality declined. At the end of 1950, Ziff-Davis moved its offices from Chicago to New York; Browne relocated to New York, but Hamling decided to stay in Chicago, so Browne became more involved once again, and sf historians such as Brian Stableford and Mike Ashley consider the result to have been a definite improvement in quality. Browne's interest in fantasy led him to start a new digest-sized magazine, "Fantastic", in the summer of 1952; it was an immediate success, and led Ziff-Davis to convert "Amazing Stories" to digest format as well. The move from the pulp format to digests was well under way in the early 1950s, and with "Fantastic"s success there was little reason to keep "Fantastic Adventures" going. It was merged with "Fantastic"; the last issue was dated March 1953, and the May–June issue of "Fantastic" added a mention of "Fantastic Adventures" to the masthead, though this disappeared with the following issue.
