An area of the Midwestern United States is often referred to as the Silicon Prairie. This region can loosely be defined as the states bordering along Interstate 29 in the Upper Midwest; specifically Nebraska, Iowa, South Dakota, Kansas, Minnesota, North Dakota, and Missouri.
The moniker was first claimed by the Gateway 2000 computer company in advertisements in the mid-1990s as its location in advertisements and promotional materials. The firm was originally founded in Sioux City, Iowa but later relocated across the border to North Sioux City, South Dakota.
