H. Igor Ansoff first published the now well-known growth vector matrix or product-market matrix in the Harvard Business Review in the Sept/Oct edition of 1957. The matrix also appeared in the book written later by Ansoff and published in 1965 – Corporate Strategy. Although this matrix was published a long time ago, it still remains one of the most popular matrices and is used to identify the basic alternatives strategies, which are options for a firm wanting to grow.
