Batman is a fictional superhero appearing in American comic books published by DC comics. The character was created by artist Bob Kane and writer Bill Finger, and first appeared in Detective Comics #27 (1939). Originally named the "Bat-Man", the character is also referred to by such epithets as the Caped Crusader, the Dark Knight, and the World's Greatest Detective.
The character became popular soon after his introduction in 1939 and gained his own comic book title, Batman, the following year. As the decades went on, differing interpretations of the character emerged. The late 1960s Batman television series used a camp aesthetic, which continued to be associated with the character for years after the show ended. Various creators worked to return the character to his dark roots, culminating in 1986 with The Dark Knight Returns by Frank Miller. The success of Warner Bros' live-action Batman feature films have helped maintain the character's prominence in mainstream culture.
