Planned obsolescence refers to manufacturing or marketing techniques generally designed to artificially shorten the life of a product, either by making it actually useless, or appear useless before it would naturally. There are several similar but subtly different types of planned obsolescence.
It should be noted that most of these types of obsolescence can and do occur naturally, without any intent to create the obsolescence. Obsolescence may be the result of true progress in developing industries such as the computer industry.
