I recall seeing this once, I believe its published every year. On just a few pages it lists every industry and who the main firms are in each one and how much revenue each had. Most inustries only have less than 5 firms that make up the overwhelming majority of the industries business.
I can’t think of what it is or where I can find it though. I recall it being in a big book with many other yearly statistics summarized. Anyone have any idea what I’m referring to? Its driving me nuts and I could really use it!
