After nearly 25 years, the secret is finally out!
Matt Groening, the creator of The Simpsons, revealed to Smithsonian magazine which of the United States' Springfields inspired the location for Fox's iconic animated hit show.
"Springfield was named after Springfield, Oregon," Groening told Smithsonian that simply. The town is located in western Oregon near Eugene. Groening, 58, grew up in Portland, Oregon.
Groening had hoped that by keeping the true state a secret, fans would believe their own Springfield was the inspiration.
"I don’t want to ruin it for people, you know?" he explained. "Whenever people say it’s Springfield, Ohio, or Springfield, Massachusetts, or Springfield, wherever, I always go, 'Yup, that’s right.' "
So why Springfield, Oregon?
"The only reason is that when I was a kid, the TV show Father Knows Best took place in the town of Springfield, and I was thrilled because I imagined that it was the town next to Portland, my hometown," Groening revealed. "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."
However, residents of Springfield, Oregon already believed their town was the inspiration, according to ABC News. Groening signed a plaque in 2007 that read, "Yo to Springfield, Oregon — the real Springfield!"
