I read that Julius Schwartz took over the Batman comics in 1964, and made some changes to make it less "silly" and changed the look of the suit/batmobile/etc. But then the TV series came out in 1966 and I heard the show's popularity reflected in the comics and brought back the campy/silly aspects.
Did the Batman tv show do away with the changes that Schwartz wanted in the early 60s? When was the Batman comics brought into the more serious tone? When O'Neill came onboard?
