Google is Alphabet’s search-engine subsidiary and a major driver of Alphabet’s market value.
Google Search handles billions of queries and supports a large advertising business. Advertising connected to search and other Google products has historically supplied most of Alphabet’s revenue, making Google central to how investors assess the parent company.
Google was founded by Larry Page and Sergey Brin while they were doctoral students at Stanford University. The company was incorporated in 1998, and its search technology became influential partly because its early ranking system evaluated links between web pages.
Alphabet became Google’s parent company in 2015 through a corporate restructuring. This arrangement separated Google’s core internet products from businesses such as Waymo and other ventures, while Google remained the dominant operating company within Alphabet.
