There was an interesting article in the
Minneapolis StarTribune about what they called the "Target Effect" on downtown Minneapolis.
Basically, the thrust of the article was focussed on the ancillary effects that a major headquarters has on a downtown area. In this particular case the article noted how the Disney Company might not have had an office in downtown Minneapolis if it weren't for the fact that Target is headquartered downtown.
What businesses in your city have a similar "Target Effect?"
