In 1949 Palmer left Ziff-Davis and was replaced by Howard Browne, who was knowledgeable and enthusiastic about fantasy fiction. Browne briefly managed to improve the quality of the fiction in "Fantastic Adventures", and the period around 1951 has been described as the magazine's heyday. Browne lost interest when his plan to take "Amazing Stories" upmarket collapsed, and the magazine fell back into predictability. In 1952, Ziff-Davis launched another fantasy magazine, titled "Fantastic", in a digest format; it was successful, and within a few months the decision was taken to end "Fantastic Adventures" in favor of "Fantastic". The March 1953 issue of "Fantastic Adventures" was the last.
