Starting in 1969, writer Dennis O’Neil and artist Neal Adams made a deliberate effort to distance Batman from the campy portrayal of the 1960s TV series and to return the character to his roots as a “grim avenger of the night”. O’Neil said his idea was “simply to take it back to where it started. I went to the DC library and read some of the early stories. I tried to get a sense of what Kane and Finger were after.”
O’Neil and Adams first collaborated on the story “The Secret of the Waiting Graves” (Detective Comics #395, January 1970). Few stories were true collaborations between O’Neil, Adams, Schwartz, and inker Dick Giordano, and in actuality these men were mixed and matched with various other creators during the 1970s; nevertheless the influence of their work was “tremendous”. Giordano said: “We went back to a grimmer, darker Batman, and I think that’s why these stories did so well…” While the work of O’Neil and Adams was popular with fans, the acclaim did little to improve declining sales; the same held true with a similarly acclaimed run by writer Steve Englehart and penciler Marshall Rogers in Detective Comics #471–476 (August 1977 – April 1978), which went on to influence the 1989 movie Batman and be adapted for Batman: The Animated Series, which debuted in 1992. Regardless, circulation continued to drop through the 1970s and 1980s, hitting an all-time low in 1985.
