This.
During my seven years at the Windsor, CO Kodak plant (see my other comment below for more) it was crazy to hear of the heyday (I was there 2002-2009, not the heyday). It was the 2nd largest Kodak manufacturing center (bested only by Rochester) and built in the 60s. It was a sprawling campus of huge concrete buildings with almost no windows (great for film!). The campus had it's own fire department and power plant.
It was a ghost of it's former self when I started but by the time I left entire buildings were vacant. At it's peak the plant had 3,200 employees. A lot of people there had worked in Rochester and from their stories I could hardly fathom the manufacturing operation there being so much larger than ours.
Maybe that's part of the reason Kodak moved so slow - all those buildings and people and essentially small factory cities are not something you can change overnight.
