One of these centers existed in a city in which I lived, Duluth, Minnesota, from 1995-2005. It was a fairly big deal for a city the size of Duluth, employing 1,000 people to start and ranging up to 1,400 at the peak. A former employee started a FB group that has a good photo of what these centers looked like in the 90s: https://m.facebook.com/photo.php?fbid=10155932292850485
