Decline Stage of the PLC
A product form has reached this stage when it becomes clear the market is no longer able to sustain itself. Like the Maturity stage, the Decline stage may last a long time especially for products that have been adopted by a large percentage of the market who are not inclined to change how they satisfy their needs (i.e., Laggards). Since the end of the product form is seen as inevitable, there are no sub-stages here.
