Jeff “Podunk” Pelline says I’m wrong when I include Uber, a San Francisco company, in Silicon Valley. Here’s what Wikipedia has to say about that:
“As more high-tech companies were established across the Santa Clara Valley, and then north toward the Bay Area’s two other major cities, San Francisco and Oakland, the ‘Silicon Valley’ name eventually came to refer to all high-tech businesses in the region. The term is now generally used as a synecdoche for the American high-technology economic sector.”
The entry also includes a map that includes the entire Bay Area in the big valley. More can be found here: https://en.wikipedia.org/wiki/Silicon_Valley
I knew Don Hoefler, the reporter for Electronic News who first used the term in the media and helped popularize it. I even got him a cup of coffee once. LOL, as they say.
