                                     The product life cycle
       Products have a limited life, not only from the consumer’s viewpoint, but also when as far as the producer is concerned. For example, a particular model
41. of car might last 5 years before production is stopped and it is replaced
42. for  by  a  completely  new  model.  New  inventions  and  technology
43. have to made many products obsolete. Fashion can be another major
44. as influence on the life of a product. Some products survive because
45. they  now sell  after in  different areas.  Products,  since they have a
46. limited life, all have a life cycle. It is obvious that different products
47. are last for different lengths of time but their life cycles have certain
48. common in elements which can be described as the introduction, growth
49. and maturity stages. The length of the product’s life cycle can often be
50. extended by a modifying the product in some way and this is often done by
51. companies to keep their products on the market for a longer period.
52. Provided that the product remains so competitive, this can be much less expensive than developing a new model.
