From Wikipedia: Planned obsolescence
Planned obsolescence (also built-in obsolescence in the United Kingdom) is the process of a product becoming obsolete and/or non-functional after a certain period or amount of use, approximately, as planned or designed by the manufacturer. Planned obsolescence has potential benefits for a producer because the product fails and the consumer is under pressure to purchase again, whether from the same manufacturer (the same or newer model), or from a competitor.
For an industry, planned obsolescence stimulates demand by encouraging purchasers to buy again sooner if they still want a functioning product. Built-in obsolescence is in many different products, from vehicles to light bulbs, from buildings to software. 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, which offers a more durable alternative.
Planned obsolescence was first developed in the 1920s and 1930s when mass production had opened every minute aspect of the production process to exacting analysis.
