 In late 1948 , as a second boom in science fiction publishing was beginning , Popular decided to revive the magazine . Jakobsson later recalled hearing about the revival while on vacation , swimming in a lake , five miles from a phone : " A boy on a bicycle showed on shore and shouted , ' Call your office . ' " When he reached a phone , Norton told him that the magazine was being relaunched and would be given to Jakobsson to edit . Damon Knight , who was working for Popular at the time , also worked on the magazine as assistant editor , although he was not credited . The relaunched magazine survived for almost three years , but the market for <unk> was weak , and when Knight left in 1950 to edit Worlds Beyond Jakobsson was unable to sustain support for it within Popular . It ceased publication with the August 1951 issue .
