Google LLC is an American multinational technology company that specializes in Internet-related services and products, which include online advertising technologies, a search engine, cloud computing, software, and hardware. Founded in September 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, Google started as a search engine that used a proprietary algorithm called PageRank to rank web pages based on their relevance and importance. Over the years, Google has expanded its services to include a wide range of products such as Google Ads, Google Cloud, YouTube, and the Android operating system, becoming one of the most influential companies in the tech industry and a key player in the global economy.
Google's mission is to organize the world's information and make it universally accessible and useful. The company has continuously evolved, acquiring various companies and technologies to enhance its offerings and maintain its competitive edge. In 2015, Google underwent a corporate restructuring and became a wholly-owned subsidiary of Alphabet Inc., which serves as the parent holding company for Google and several former Google subsidiaries. This restructuring allowed Google to focus on its core business while Alphabet could manage its other ventures, including those in health, self-driving cars, and other innovative technologies.
