Jerry and David's Guide to the World Wide Web

Yahoo started out in 1994 as "Jerry and David's Guide to the World Wide Web," a list of websites organized by category put together by Stanford graduate school students Jerry Yang and David Filo.

Yang and Filo quickly changed the site's name to "Yahoo" (in nerd fashion, they joked that Yahoo stood for "Yet Another Hierarchical Officious Oracle"). Yahoo (YHOO, Tech30) officially incorporated on March 2, 1995.

The site rapidly grew in popularity, becoming one of the Web's go-to search engines and Web portals. In the 1990s, Yahoo was in many ways like Google (GOOGL, Tech30) is today: the starting point for many people when they browse the Web.
