Batman debuted in ''Detective Comics'' #27 in 1939. Early stories were dark, featuring a Batman who did not shy away from killing. The character quickly became popular, leading to his own solo title in 1940. Robin, Batman's sidekick, was introduced in 1940, lightening the tone and boosting sales. Over the next few years, Batman's rogues' gallery expanded with iconic villains like the Joker and Catwoman.
The 1950s saw Batman in lighter, science fiction-influenced stories. However, declining sales led to a 1964 revamp by editor Julius Schwartz, who returned Batman to his detective roots and updated his appearance. The 1966 Batman TV series introduced a campy, humorous tone, which was reflected in the comics until its cancellation in 1968. In the 1970s, writers Dennis O'Neil and Neal Adams restored Batman's dark, gritty nature, a trend that continued despite fluctuating sales.
