iii. Planned obsolescence

In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is a policy of planning or designing a product with an artificially limited useful life or a purposely frail design, so that it becomes obsolete after a certain pre-determined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as unfashionable. The rationale behind this strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle"). It is the deliberate shortening of a lifespan of a product to force people to purchase functional replacements.

In 1960, cultural critic Vance Packard published The Waste Makers, promoted as an exposition of "the systematic attempt of business to make us wasteful, debt-ridden, permanently discontented individuals". Packard divided planned obsolescence into two sub categories: obsolescence of desirability and obsolescence of function.
