There was a ton of government work over there. Many tech in the U.S. are also funded with DARPA, NSF, etc. By the time it hits press, the involvement of U.S. government or academia is usually minimized if we&#x27;re talking a product rather than research result.<p>Anyway, this great (and long...) book will give you an idea just how much the U.S. government (esp defense) funded our computing advances back in the day. A chunk of that probably went to Silicon Valley, too.<p><a href="http:&#x2F;&#x2F;monoskop.org&#x2F;images&#x2F;d&#x2F;d4&#x2F;Roland_Alex_Shiman_Philip_Strategic_Computing_DARPA_and_the_Quest_for_Machine_Intelligence_1983-1993.pdf" rel="nofollow">http:&#x2F;&#x2F;monoskop.org&#x2F;images&#x2F;d&#x2F;d4&#x2F;Roland_Alex_Shiman_Philip_St...</a>
