Yahoo Inc. invested billions of dollars in its Internet search engine during the past six years before realizing it made more sense to entrust the job to an outsider _ something the company's co-founders concluded shortly after they started a Web directory in the mid-1990s.

Yahoo! celebrates 20th anniversary

It's been 20 years since two Stanford University electrical engineering students created a small website that would become the tech giant Yahoo! Company founders Jerry Yang and David Filo debuted "Jerry and David's Guide to the World Wide Web" in January 1994. In its first iteration, the site was a directory other pages on the web, organized in a hierarchy.

It was not the massive searchable index of online destinations that the Yahoo! search engine is today. The site grew faster than the pair expected. They renamed it Yahoo!,
an acronym for, "Yet Another Hierarchical Officious Oracle," and on March 2, 1995 it was incorporated. As we celebrate 20 years of purple and yodeling (the company's iconic audio trademark), here's a look back at key moments in Yahoo!'s history. (Yahoo News)
