The product life cycle is normally shown generically. However, not all product life cycles are the same in time or form.

For example, we can look at a simple product such as baking soda, which has been a product in the marketplace for well over 200 years. On the other hand, when we look at technological products such as computers, printers, smartphones, and tablets, the life cycle is often measured in weeks, as new products are coming out rapidly.
