Reading A Goolge Anyone who has ever used the Internet has seen Google, and many people would just “google it” when they try to find information about something on the Internet. As the world’s most popular Internet search engine, Google is one of the greatest examples of online success. It all began in January 1996 as a research project at Stanford University by Ph.D. student Larry Page. Trying to find a better way for web users to search for relevant pages, Page had an idea that this could be achieved by examining the relationships between web pages. He thought that web pages which had the most links to them from other web pages must be the most popular. The technique appeared to be successful. Page and his partner Sergey Brin set up their company on September 7, 1998 and registered the google.com the following week. The search engine quickly grew in popularity and in 2000 Google began to sell advertising on their website. After a few years of growth fueled by eager investors, Google went public. Many Google employees became instant millionaires. Google has acquired YouTube.com which is the Internet’s largest video-sharing website and continues to add new features every day including tool bars, email, and advertising. Of course, with growth and success there also comes competition. Microsoft has tried to acquire Yahoo in order to compete with Google in the Internet search engine area. In addition to its growth and popularity, Google has also been named the number one company to work for in the United States. It tends to stay away from typical office designs and tries to make the office a place where employees are comfortable and free to excel at their work. Today, Google has become a multinational corporation in Internet-related services and products. These include search, cloud computing, software, and online advertising technologies. And it is the leader in terms of ad-based revenue on the web. The brain child of two students has become a billion-dollar company and one of the best-known trademarks in the world. Google’s history serves as a perfect model and inspiration for Internet entrepreneurs today
