Perceived obsolescence is a kind of perception of “staying up to date and maintaining social status” created by companies on people. This perception is usually created by advertisements. Although this perception is in many sectors such as fashion, nowadays, the target is especially technological products because we live in a technological age. Technological products are no longer for need as before; they are taken for color, popularity, etc. So it’s like following the fashion program, whatever’s in this year’s creation is taken. The best-known example of this is the iPhone. The iPhone 1, produced by Apple in 2007, is expected to be 12 in 2020. 12 updated top model in 13 years (excluding models such as pro vs). You buy the most popular phone in the year you bought it, not because you actually need it, but as popular. As if you pick up that phone, you will be up to date and you will not be left behind, here is the classic herd psychology. However, when you get that phone, it’s not too long before a top model comes out. New features have been added, existing features have been further improved; camera, battery, etc. This time, that phone you get because it’s actually popular suddenly seems outdated or garbage to you. Even though you don’t need it, now the new product becomes psychologically your need, and you find yourself buying a top model phone. In addition even the company has set a strategy, the old model that you have is slowing down after the new model comes out. So if you don’t want to follow this herd psychology, the company is forced to make you up and you have to. Then again the same vicious circle after buying a top model. Better, more beautiful, more popular, more up-to-date, better quality, better photographer etc. In short, there is no limit to this. In fact, the more we consume, the more we become depleted. We can call it a black hole for perceived or planned obsolescence.
