I was looking at some trivia about the 60's TV show and found these trivia points. My question- are they true? (please forgive my ignorance)
-The character of Batgirl was created for the television series and was written into the Batman comic books.
-The Riddler was just a minor and forgettable villain in the comics. This series is responsible for turning him into one of the most popular villains in Batman's rogues gallery.
-Batman creator Bob Kane noted that this series saved the Batman comic series from cancellation when the show revived the character's popularity.
-After the show was canceled, the character's comic series took on a dark and deadly serious tone that was reminiscent of the original comics in the late 1930s as a reaction to the TV show's light touch.
-Mr. Zero was renamed Mr. Freeze for this series. The named change eventually made its way into the comics as well.
-Before the series began the comic book Batman had a black bat emblem on his gray chest which was had to see on the screen. To make it easier to see a yellow oval was added around the bat emblem. The oval was added to the comic book costume also. After the series ended the comic book costume eventually went back to no oval around the bat symbol.
