Historically, the first American place named Springfield was Springfield, Massachusetts, founded in 1636 by William Pynchon.

During the 19th century, Springfield became one of the world's leading centers of the Industrial Revolution, pioneering advances in interchangeable parts.

The television show The Simpsons is set in a town generically named "Springfield", without indicating a state. Creator Matt Groening has suggested in interviews that he chose the name because of its ubiquity; the show's intentionally contradictory information about the location of the town prevents matching the fictional Springfield to a real one. Groening revealed in 2012 the town referred to Springfield, Oregon, which is close to his hometown of Portland.^[2]

A "Springfield" was also the setting of the early 1950s radio and television program, Father Knows Best, as well as the 1950s soap opera The Guiding Light, which continued as the CBS soap opera Guiding Light through 2009. "Springfield" was also the given locale for the 1957-1963 television series Leave it to Beaver.
