The Internet is a big place. Nobody has the time to look at every web page to find something. Yahoo can help us to find what we need.
David Filo and Jerry Yang, two Stanford University students, started Yahoo in 1994. They started by making a list of their favorite web pages. When their list got bigger, they made a database(数据库) to keep their information. They let everybody use it for free. Soon, thousands of people began to use their service.
They then made a new kind of software. It would take some information and arrange it for someone to look at. If you search for, say, “Hangzhou”, the engine will give you a list of web pages with that word. Yahoo became a public company in 1996. Filo and Yang, still young students, became rich. As their company grew, they went on working hard. They improved their software. They also added more services, like shopping, free e-mail, many different countries and languages.
Yahoo. com is famous on the Internet. And unlike most other web companies, Yahoo makes much money in fact.
