This is a 3D rendition of Silicon Valley and the network between the various cities and Stanford that allowed Silicon Valley to take shape. Castells’ talks about this network on pages 62 and 63. He spends time discussing the distance between various places such as San Francisco and San Jose, and Palo Alto. Castells writes, “It was this technology transfer from Shockley to Fairchild, then to a network of spin-off companies, that constituted the initial source of innovation on which Silicon Valley and the micro-electronics revolution were built” (63). For this network, the cities act as nodes for companies and development taking place within a specific area, in between all of them, that becomes known as Silicon Valley.
