Concept of Product Life Cycle. First referenced in the 1920s, the product life cycle applies biological knowledge to products. In nature, a seed is planted, begins to sprout, becomes an adult then eventually withers away and dies. The product life cycle focuses on introduction (seed), growth (sprout), maturity (tree) and decline (death) phases. Each phase has its own marketing mix strategy and implications regarding product, price, distribution and promotion.
