old vs new water heater tanks

How come the older tanks lasted longer than the new tanks? What changed in their manufacture also when did the shorter life taking effect?

As with all manufacturing, the makers of almost any product tend to try and save on material cost. Thinning metal, changing the composition of products all lend to a cheaper product over the years. There is no definite time frame. It just happens.
