Here's a tourist's guide to nerd nirvana for those more interested in seeing the suburban home where The Woz built the first Apple computer alongside Steve Jobs than the spooky prison in the Bay where the Birdman of Alcatraz once served time alongside Machine Gun Kelly.
Jobs was one of many entrepreneurs influenced by the HP legacy as a teenager, eventually inspiring him and his engineering friend, Steve "The Woz" Wozniak, to begin working on Apple's first computer in the home of Jobs' parents.
After they started Google in 1998, co-founders Larry Page and Sergey Brin built what would become the world's dominant search engine in a garage and room they rented from Susan Wojcicki, whom they later hired (she now runs YouTube for them).
The hub of its Mountain View, California, campus is at 1600 Amphitheatre Parkway, with other Google offices sprawling almost all the way down to the nearby NASA Ames Research Center, where Page and Brin keep personal jets in a hangar.
Walk down Charleston Road and you are bound to see one of the company's employees (also known as "Googlers") cruising on yellow, green, blue and red bikes placed outside all the offices to get to meetings more quickly.
The menu includes Cupcake, ''Donut, ''Eclair, ''Froyo, ''Gingerbread, Honeycomb, ''Ice Cream Sandwich, ''Jelly Bean, ''KitKat, ''Lollipop and Marshmallow.
[...] in the Google store on the main campus, you can buy company-branded merchandise, including shirts, hats, mugs, pens and even notebooks (the kind with paper).
The giant thumbs-up sign replicating Facebook's symbol for liking a post has become one of the most photographed spots in Silicon Valley since the social networking company moved its headquarters from Palo Alto to 1 Hacker Way in nearby Menlo Park five years ago.
