The full form of Yahoo is Yet Another Hierarchical Officious Oracle. It is an American web service provider that provides a variety of services such as the search engines Yahoo Search, Yahoo Mail, Yahoo News, Yahoo Sports, Yahoo Finance and Yahoo Native. It is headquartered in Sunnyvale, California. Yahoo was founded by David Robert Philo and Jerry Yang almost 28 years ago in January 1994. At first, it was named “Jerry and David’s Guide to the World Wide Web” which was a human edited web directory. Later in March 1994, it was renamed to its current name Yahoo.

During the 1990s, Yahoo experienced rapid growth, and in 1996 its share price increased by 600% in just two years. By 1998 Yahoo was the most popular portal for web users and their human edited Yahoo directory had become the most popular search engine. As Google and Facebook became more popular, its use declined sharply in the 2000s. As of now, Yahoo, is operated by Yahoo Inc. , which is 90% owned by Apollo Global Management Inc. and 10% by Verizon Communications Inc.
