The first team of superheroes in comic book history, the Justice Society of America, or JSA, is a DC Comics superhero group conceived by editor Sheldon Mayer and writer Gardner Fox. The JSA first appeared in All Star Comics #3 (Winter 1940).
Unlike subsequent "all-star" teams, the JSA was limited to heroes appearing in comic strips in anthology titles, but not at the time featured as the stars of their own comic books, because the publisher wanted to bring attention to lesser known characters. Therefore, Superman and Batman were only honorary members and Flash and Green Lantern's early tenures were brief, ending when each character was awarded his own comic book series. However, a 1944 change in policy allowed them back into the group. Other popular members were Hawkman, the Spectre, Hourman, Doctor Fate and the Atom.
