Other products stay in one stage longer than others. For example, in 1992, PepsiCo introduced a product called Clear Pepsi, which went from introduction to decline very rapidly. By contrast, Diet Coke entered the growth market soon after its introduction in the early 1980s and then entered (and remains in) the mature stage of the product life cycle. New computer products and software and video games often have limited life cycles, whereas product categories such as diamonds and durable goods (kitchen appliances) generally have longer life cycles. How a product is promoted, priced, distributed, or modified can also vary throughout its life cycle. Let’s now look at the various product life cycle stages and what characterizes each.
