Larry Page and Sergey Brin founded Google while PhD students at Stanford University. Their research focused on creating a search engine that could find interconnections between pages on the internet. They built PageRank technology to rate page quality and relevance. As Google grew popular for its free search service, it introduced paid listings like AdSense to generate revenue. Google maintained its intellectual capital through human resources improving software, acquisitions expanding offerings, and a 5-step ICM model to identify, map, measure, manage and report on intellectual capital. This allowed Google to become a leading company beyond just search across various products and markets.
