Amazing Stories [SEP] Introduction
Palmer as editor. Palmer made the magazine successful though it was not regarded as a quality magazine within the science fiction community. In the late 1940s "Amazing" presented as fact stories about the Shaver Mystery, a lurid mythos that explained accidents and disaster as the work of robots named deros, which led to dramatically increased circulation but widespread ridicule. "Amazing" switched to a digest size format in 1953, shortly before the end of the pulp-magazine era. It was sold to Sol Cohen's Universal Publishing Company in 1965, which filled it with reprinted stories but did not pay a reprint fee to the authors, creating a conflict with the newly formed Science Fiction Writers of America.
