Yes, it was huge, and made up of a lot of units independently. They used to joke that the company was a technology vendor's delight, since they weren't very strict with what technology a department can choose to use, leading to finding a bit of almost every vendor somewhere. When I was there they had a push towards centralising IT between the divisions, providing common services and support to get economies of scale. I suspect this is a cyclical trend over decades.
