Definition: The word 'California Concept' has been a buzzword in recent years due to its association with innovative California-based companies, such as Google's Silicon Valley headquarters and Facebook's data center. The term was popularized by Bill Gates, who famously said, "I have two grandchildren [Google's CEO] and I am going to build a state of the art data center at my office." This phrase has since become an acronym for California-based companies that are working on innovative projects in the Bay Area.
