Yahoo! - Born in 1994
David Filo and Jerry Yang started Yahoo!
in 1994. Originally it was a highly regarded directory of sites that
were cataloged by human editors. This directory provided an extensive
listing of websites supported by a network of regional directories. In
2001, Yahoo! started charging a fee for inclusion in its directory
listing. Yahoo!’s action helped control the number of sites listed and
helped cover costs with additional revenue.
Initially, Yahoo! used secondary search engine services to support
its directory. Partnerships have included agreements with Inktomi and
Google. In October 2002, Yahoo shifted to crawler-based listing for its
search results. In 2004, Yahoo! purchased Overture’s pay-per-click
service, which had only months earlier purchased AltaVista and
AlltheWeb, and Inktomi’s search database. With these acquisitions,
Yahoo! combined these tools to create its own search index. Today,
Overture is renamed Yahoo! Search Marketing and provides paid search
advertising revenue. The Yahoo! Directory remains one of the top
indexes powering search listings.
