PD Cycle

Please describe the different stages of the Product Life Cycle (PLC), with at least two examples.

One example is a product that follows a typical PLC stages, and appears to be in the declining stage or about to become obsolete.

The other example can be a product that seems to defy the PLC theory, something that appears to be lasting forever, or comes and goes very quickly. You are encouraged to use the products from your Marketing Plan.

Comment on the usefulness of the PLC theory in marketing a product.
