The introduction stage of the product life cycle is where a new product is launched into a market. In the growth stage of the product life cycle, the market has accepted the product and sales begin to increase. In the maturity stage of the product life cycle, sales will reach their peak. In the decline stage of the product life cycle, sales will begin to decline as the product reaches its saturation point.
The product life cycle can be divided into several stages characterized by the revenue generated by the product or range of products, such as a brand. The life cycle can be very short, as pertains to a product that is for an event, such as a Christmas toy, or very long such as a watch or a car. For most products, the beginning of the life cycle is the product development stage. Companies develop new products all the time and a small percentage of those reach the market.
