High Quality Content by WIKIPEDIA articles! Yahoo! was started in a Stanford University campus trailer. It was founded in January 1994 by Jerry Yang and David Filo, who were Electrical Engineering graduate students when they created a website named "Jerry and David`s Guide to the World Wide Web". The Guide was a directory of other websites, organized in a hierarchy, as opposed to a searchable index of pages. In April 1994, Jerry and David`s Guide to the World Wide Web was renamed "Yahoo!". The yahoo.com domain was created on January 18, 1995.
