Argosy was an American magazine, founded in 1882 as The Golden Argosy, a children's weekly, edited by Frank Munsey and published by E. G. Rideout. Munsey took over as publisher when Rideout went bankrupt in 1883, and after many struggles made the magazine profitable. He shortened the title to The Argosy in 1888 and targeted an audience of men and boys with adventure stories. In 1894 he switched it to a monthly schedule and in 1896 he eliminated all non-fiction and started using cheap pulp paper, making it the first pulp magazine. Circulation had reached half a million by 1907, and remained strong until the 1930s. The name was changed to Argosy All-Story Weekly in 1920 after the magazine merged with All-Story Weekly, another Munsey pulp, and from 1929 it became just Argosy.
