The point of these examples was that it is possible to produce dozens of high quality product with attention details. These companies did so many years, even spanning decades. Their failures had more individual flavors and I don&#x27;t think it&#x27;s generalizable to &quot;they had lots of products&quot;. In fact, companies like Microsoft is still able to survive precisely because they had built up long tail and failure in one or two products didn&#x27;t entirely collapsed the company.<p>Apple&#x27;s core business requirement is high margins. This is only possible if they keep spawning new big product lines as big as iPhone (i.e. Looking for lucky unicorn) OR building long tail of products where single loss of market share doesn&#x27;t impact entire company.
