Google is officially incorporated by Larry Page and Sergey Brin, though the technology their new website would be based on had been in development for several years. Google follows a wave of portal-based search engines and returns to a focus on simple, text-based search. Their algorithm’s key differentiator is PageRank, which uses the back-links a webpage receives to determine its relative strength in the rankings. Started in a garage, over time, Google would grow to become one of the biggest web-based companies in the world.
