130 free Silicon Valley trivia questions with answers — technology quiz, new questions added Aug 2026.
This Silicon Valley trivia quiz covers both things people mean by the name. Most of it is the real place: the Santa Clara Valley that was once the Valley of Heart's Delight, Frederick Terman and Stanford, the garage on Addison Avenue where Hewlett-Packard began, William Shockley's lab and the traitorous eight who left to found Fairchild, Intel's first microprocessor, the venture firms of Sand Hill Road, Xerox PARC, the Homebrew Computer Club and the dot-com bubble. The rest is Mike Judge's HBO comedy: Richard Hendricks, Pied Piper, Hooli, Erlich Bachman and the finale that made the team crash their own launch. About a third of the questions are easy for anyone who follows tech, a third need a working knowledge of the region's history and the show's plot, and the rest reward the people who know which journalist popularised the name, who the first tenant of Stanford Industrial Park was and which cast member's early death shaped season one. Every answer was checked against Wikipedia's articles on the region, the HP Garage, the traitorous eight and the series before publishing, and each question carries the sentence that establishes it. If you think one is wrong, use the report button and we will look again.
