what did jerry yang and david filo develop
History of Yahoo! Yahoo! was started at Stanford University. 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!".[1][2] The yahoo.com domain was created on January 18, 1995.[3]
