In an extensive interview with Smithsonian magazine, the Oregon-born creator of The Simpsons purportedly confirms with interviewer Claudia De La Roca what has long been rumored: That the Springfield Homer, Marge, Bart, Lisa, Maggie, and the rest of the 25-year-old hit cartoon series cast call home is, in fact, named in honor of Springfield, Oregon.

"Springfield was named after Springfield, Oregon. The only reason is that when I was a kid, 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 told interviewer Claudia De La Roca. "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."

Groening later elaborated, telling TV Guide, "I never said Springfield was in Oregon.”
