The first U.S. science fiction (sf) magazine, Amazing Stories, was imported into the U.K. from its launch in 1926, and other magazines from the U.S. market were also available in the U.K. from an early date. However, no British sf magazine was launched until 1934, when Pearson's launched Scoops, a weekly in tabloid format aimed at the juvenile market. Soon Haydn Dimmock, Scoops' editor, began to receive more sophisticated stories, targeted at an adult audience; he tried to change the magazine's focus to include more mature fiction but within twenty issues falling sales led Pearson's to kill the magazine. The failure of Scoops gave British publishers the impression that Britain could not support a science fiction publication.
