Defined by Wikipedia as:

Planned obsolescence or built-in obsolescence in industrial design 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.[1] Planned obsolescence has potential benefits for a producer because to obtain continuing use of the product 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 sooner if they still want a functioning product. Built-in obsolescence is used in many different products. 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

There is also a related phenomenon: built-in obsolescence is based upon creating (or at least seeming to create) “better” products every few years so that consumers see no merit in repairing ageing items. There’s also a general trend towards designing without repairability as a criterion, and as a consequence many items are not repairable. A good example is typcial household refigerators: their efficiency has not noticeably increased over recent times, but elements such as the interior door “shelves” are typically made of single-cast, model specific piece of plastic. In the even this breaks it is generally impossible to repair, leading to “consumption” of another refrigerator unit.
