Jerry Yang

A former Ph.D. student in electrical engineering at Stanford University, Yang and classmate David Filo founded Yahoo in 1994 as a way of keeping track of their personal interests on the Internet. Within months, they converted Yahoo to allow users to search the Internet and to create customized lists of sites. Yahoo developed into a major web portal and an $11 billion business within four years. Yahoo continues to be among the top Internet directories and search engines.
