One of the first items with planned disintegration was the light bulb.
About 100 years ago some business man decided more money by making products that fail over time . . .
Consider this light bulb . . .

now-a-days washing machines, fridges etc are all designed to fail after so many preplanned hours of use.
This auto destruction is seven years based upon the average number of hours of normal useage.
That is why buying extra product protection is wasting money, the product has such a low chance of failing you are simply giving your money away . . .
With the light bulb, there was a industry cartel.
In a perfect market situation, the "planned disintegration" doesn't quite make sense. If you buy an item from brand A and it breaks after X years (and the customer would have expected it to last for longer), then the customer is likely to chose brand B when buying the replacement.
Of course, the "perfect market" doesn't exist. I've been having massive problems with leaky water tanks in my boat, it really doesn't make sense but I keep on buying exactly the same brand, in the short term it seems easier for me to just replace the faulty parts with replacements that fits in with the least amount of work.
