Thanks. This looks more like a "how to manage a company" text book. I was looking more for a historical view of these companies. For example, all history books on HP I found focus on their rise and "the miracle" of building a company out of a garage, not exploring their later years, like selling/spinning off parts of their core business and the reasons for getting where they are now. Maybe 20-30 years ago is still too early to get a good perspective on those events though.
