By 1964, sales of Batman titles had fallen drastically. Bob Kane noted that, as a result, DC was "planning to kill Batman off altogether". In response to this, editor Julius Schwartz was assigned to the Batman titles. He presided over drastic changes, beginning with 1964's Detective Comics #327 (May 1964), which was cover-billed as the "New Look". Schwartz introduced changes designed to make Batman more contemporary, and to return him to more detective-oriented stories. He brought in artist Carmine Infantino to help overhaul the character. The Batmobile was redesigned, and Batman's costume was modified to incorporate a yellow ellipse behind the bat-insignia. The space aliens, time travel, and characters of the 1950s such as Batwoman, Ace, and Bat-Mite were retired. Bruce Wayne's butler Alfred was killed off (though his death was quickly reversed) while a new female relative for the Wayne family, Aunt Harriet, came to live with Bruce Wayne and Dick Grayson.The debut of the Batman television series in 1966 had a profound influence on the character. The success of the series increased sales throughout the comic book industry, and Batman reached a circulation of close to 900,000 copies. Elements such as the character of Batgirl and the show's campy nature were introduced into the comics; the series also initiated the return of Alfred. Although both the comics and TV show were successful for a time, the camp approach eventually wore thin and the show was canceled in 1968. In the aftermath, the Batman comics themselves lost popularity once again. As Julius Schwartz noted, "When the television show was a success, I was asked to be campy, and of course when the show faded, so did the comic books."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" in Detective Comics #395 (Jan. 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 (Aug. 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.
