WINTER: Originally implied to be set in New York City, Batman’s “hometown” of Gotham was named for the first time in BATMAN #4. According to comic book historian and icon Jim Steranko, Bill Finger gave Gotham City its name…
“Originally I was going to call Gotham City 'Civic City.' Then I tried 'Capital City,' then 'Coast City.' Then I flipped through the New York City phone book and spotted the name 'Gotham Jewelers' and said, 'That's it,' Gotham City. We didn't call it New York because we wanted anybody in any city to identify with it. - Bill Finger
