My Mark: 6/10
A lot - A LOT - of examples. The issue is that most of them are now outdated, we still talk about Cola, CD, and cars. It is also a very US market-oriented book. I do not agree about quite a few aspects of the positioning except the very interesting reference to "créneau" also known as a niche.
I normally don't post a book that did not inspire me but since this is "a marketing classic" I just wanted to recommend you invest your time somewhere else.
