Francis Scott Street and Francis Shubael Smith began their publishing partnership when they bought an old fiction magazine. In 1858 they bought the New York Weekly Dispatch, in 1933 they bought some tittles from Clayton Magazine which included "Astonishing Stories". In 1937 Street & Smith discontinued many of their pulp tittles such as "Complete Stories" and "Top-Notch".
Street & Smith stopped publishing pulps and comics in 1949 when sales declined due to the advent of television. They sold many of their tittles to Popular Publications.
