What Does Yahoo Stand For?

In the tech world, the word Yahoo, followed by an exclamation point, stands for "Yet Another Hierarchical Officious Oracle." The term was used by David FIlo and Jerry Yang in 1994 to name their Internet search engine. Both were electrical engineering PhD candidates at Stanford University at the time.

The dictionary term for Yahoo that led the two students to choose it as a name was, "rude, unsophisticated uncouth." The two incorporated Yahoo! into a business in 1995, and left their PhD programs to continue to shape the search engine. Eventually, the company made them both billionaires, and the search engine developed into one of the first context-driven databases for online Internet searches.
