Meet the world’s most enduring product

Companies can survive for aeons, but their products are usually ephemeral. Apple may be the world’s most valuable business, yet the Apple II computer and the original Mac that provided the early foundation of its success live in museums, if at all. Apple’s smartphone rival, Samsung, began by selling noodles. Ford’s latest F-150 Lightning electric pickup truck shares little with the Model T except for four wheels. The dictum “If it ain’t broke, don’t fix it” carries little weight in a world of evolving technologies, business models and consumer tastes.
