Pulp era of science fiction

In the history of science fiction, the pulp era (occasionally pulp age^: 91) is a period subject to various definitions. It is commonly held to have begun in 1926, the year the first science fiction magazine—Hugo Gernsback's Amazing Stories—was launched. The end point is usually placed in the 1950s, when the pulp magazines ceased publication. Various largely similar definitions exist that differ by a few years in either direction at the beginning or end of the period, though there are some outliers—by the broadest definition the era began in 1896 with the first (albeit genre-nonspecific) pulp magazine Argosy, and by the narrowest it ended in 1937 with the onset of the Golden Age of Science Fiction.
