Steve Jobs is a great example when it comes to marketing and entrepreneurship. The way he has build his company(s) and always remained true to himself and his values is extraordinary.
There are not many companies in the world as big as Apple therefor you can call it exceptional how their values remained the same from a small company in a garage to one of the biggest brand in the tech-industry.
Steven Jobs belongs in my opinion to a select group of people who repeatedly has proven that if you build quality products or services with passion and the right presentation, you can turn every product you make in a success.
In this article I describe what I learned form watching Steven Jobs talk about marketing en how he used it to build up Apple by promoting its products.
