First time accepted submitter TheSeventh writes "Simpsons creator Matt Groening has revealed the location of the real Springfield: It's in Oregon. In an interview with Smithsonian magazine, Groening credits the name to the hit TV show Father Knows Best. The show 'took place in the town of Springfield, and I was thrilled because I imagined that it was the town next to Portland, my hometown,' he says. 'When I grew up, I realized it was just a fictitious name. I also figured out that Springfield was one of the most common names for a city in the U.S. In anticipation of the success of the show, I thought, 'This will be cool; everyone will think it's their Springfield.' And they do.'"
