Apple's Organizational Structure
If you have ever seen the movie about Apple and Steve jobs, you can see how much Steve controlled Apple. The Board actually fired him at one point which you can imagine he didn't like. He eventually was brought back on and became CEO again. The structure of Apple with Steve Jobs at the helm looked a lot like the picture below:

This had Steve at the center of every decision. Of course the Board had some influence but Steve was in charge. He was the reason for the crazy success. Now with the leadership looking like this picture below, Apple is not controlled as much by CEO Tim Cook, but more like a traditional World Incorporation.
