Yahoo! (/ˈjɑːhuː/, styled yahoo! in its logo) is an American web services provider. It is headquartered in Sunnyvale, California, and operated by the namesake company Yahoo! Inc., which is 90% owned by investment funds managed by Apollo Global Management and 10% by Verizon Communications.
It provides a web portal, search engine Yahoo Search, and related services, including My Yahoo!, Yahoo Mail, Yahoo News, Yahoo Finance, Yahoo Sports and its advertising platform, Yahoo! Native.
Yahoo was established by Jerry Yang and David Filo in January 1994 and was one of the pioneers of the early Internet era in the 1990s. However, its use declined in the late 2000s as some of its services were discontinued, and it lost market share to Facebook and Google.
