Product Life Cycle (PLC)
A new product passes through set of stages known as product life cycle. Product life cycle applies to both brand and category of products. Its time period vary from product to product. Modern product life cycles are becoming shorter and shorter as products in mature stages are being renewed by market segmentation and product differentiation.
Companies always attempt to maximize the profit and revenues over the entire life cycle of a product. In order to achieving the desired level of profit, the introduction of the new product at the proper time is crucial. If new product is appealing to consumer and no stiff competition is out there, company can charge high prices and earn high profits.
