This document discusses the history and components of Google. It describes how Google started as a search engine created by Larry Page and Sergey Brin to help people sort through the growing amount of online content. Google introduced AdWords which allowed advertisers to bid on keywords and generated revenue to support the company's growth. Google then acquired and developed other digital products like YouTube, Google Maps, and Gmail to expand its business and deliver more advertising opportunities as its user base increased. Today Google remains dominant in search and digital advertising through its variety of products and services.
