Interesting book, if you are into some industrial historics.
Nice to see how this industry has evolved from small individual companies to large global players. All cross links between different companies and the important people involved, gives a nice insight in how few people have put a stamp on this complex global industry.
I gave it three stars as I found it a little hard to read, because the way of writing is not that triggering. A lot of facts and figures and a pretty flat way of telling, but historical/chronological correct.
So all-in-all, for the interested readers a nice-to-read.
