Obsolescence of a product is important and plays a major role when product is no longer as popular or successful anymore. The company is wasting their resources and time creating more of these products, when they are not selling at the rate they were initially at release, or sometimes not even selling at all. As others have mentioned as well, when products are suddenly removed from the market, this may cause a stir among the customers. The disappearance of the product may not be expected by the customers, and the demand may come back. If this occurs, after the product is removed, the company can work to improve it and relaunch it in the market. With the technological advancements being done, it is very common now for many products being obsolete because they cannot keep up with the market.
