I hear about it all the time: planned obsolescence. People can't believe that their computer parts are already breaking and their iPhone started to slow down just days before the next generation of the phone was released. Your TV seems to be programmed to have bugs whenever the manufacturing company wants to push a new product. Companies break their own products to get you to buy more of the same product: light bulbs, phones, batteries, cars, microwaves, computer screens, and even your car key transponder will all stop operating eventually. Either the marketing team or the designers wanted it that way, right?
