Microsoft is 40 years old.  IBM is 100.  Some other old companies might not be considered &quot;tech&quot; anymore, but only because their market&#x2F;product are better defined (e.g. Ford is an auto maker, but the assembly line and the concept of an automobile itself place Ford as the &quot;tech&quot; darling of 110 years ago, IMHO).  I think if you don&#x27;t see old tech companies today, it&#x27;s because over time their public appearance has quietly lost the &quot;how&quot; (new technology, automation) and only left the &quot;what&quot; (search, ipods, advertising, rockets).  But that doesn&#x27;t mean old tech companies die.
