Other interesting things he did - Horizontal integration: buying up refineries in every state Vertical integration: acquiring pipelines, home delivery systems, etc Free: in some cases Rockefeller gave away things for free or below cost. In China they had never used kerosene lamps, so Rockefeller gave away the lamps for free in order to get the Chinese to start using them and eventually buy Standard Oil's kerosene -He also would undercut competitors in the refinery biz (sometimes below cost) in order to drive them out of business and force them to sell their refineries to him.
How is any of this useful?
Some people argue that Bill Gates is an iteration of Rockefeller's monopolist approach to business. By creating standards (Windows as the go to OS for PCs) he would be able to get consumers to use MSFT's related products - Office, Internet Explorer, etc.
There is a great book called Titan by Ron Chernow where you can read an excellent account of how Rockefeller rose from being a lowly accountant to founding and operating Standard Oil.
I'm confused by what you mean about "business models", here. I doubt that you could say that Henry Ford had a "business model" when he went into business; what he had was a mechanical knack, and the idea that cars should be manufactured the way that guns were at the time. That turned out to be a great idea -- and one that pretty much all automotive manufacturers today have completely forgotten -- but I would hesitate to call it a "business model".
Business strategies, however, are pretty damn useful, and Guy Kawasaki's book is about nothing but. It was the first book I read, years ago, that turned me on to the idea of having a business.
