Yahoo

Yahoo was born in April 1994 and was an incredibly popular search engine and portal in the ’90s. Yahoo search was mostly human-powered, at least until June 2000 when a then-unknown search engine called Google began powering Yahoo’s organic search results. That deal continued until 2004, when Yahoo started using its own search technology. Since 2010, Yahoo’s organic search results have been powered by Microsoft’s search engine, Bing.
