Planned obsolescence

Definition
Planned obsolescence (also called built-in obsolescence) is a policy of planning or designing a product with a limited useful life, so it will become obsolete, that is, unfashionable or no longer functional after a certain period of time. Planned obsolescence has potential benefits for a producer because the consumer is under pressure to purchase again, whether from the same manufacturer (a replacement part or a newer model), or from a competitor which might also rely on planned obsolescence.

For an industry, planned obsolescence stimulates demand by encouraging purchasers to buy again sooner if they want the latest product. There is, however, the potential backlash of consumers who learn that the manufacturer invested money to make the product obsolete faster; such consumers might turn to a producer (if any exists) that offers a more durable alternative.
