In their 1981 book, Positioning: The Battle for your Mind, Al Ries and Jack Trout describe how positioning is used as a communication tool to reach target customers in a crowded marketplace. Jack Trout published an article on positioning in 1969, and regular use of the term dates back to 1972 when Ries and Trout published a series of articles in Advertising Age called "The Positioning Era." Not long thereafter, Madison Avenue advertising executives began to develop positioning slogans for their clients and positioning became a key aspect of marketing communications.
Positioning: The Battle for your Mind has become a classic in the field of marketing. The following is a summary of the key points made by Ries and Trout in their book.
