Al Ries and JTrout Books
A product's position is how potential buyers see the product. Positioning is expressed relative to the position of competitors. The term was coined in 1969 by Al Ries and Jack Trout in the paper "Positioning" is a game people play in today’s me-too market place" in the publication Industrial Marketing. It was then expanded into their ground-breaking first book, "Positioning: The Battle for Your Mind".
