Yahoo! Inc. (NASDAQ: YHOO) is an American internet corporation founded in Santa Clara, California and headquartered in Sunnyvale, California, United States. The company is perhaps best known for its web portal, search engine (Yahoo! Search), Yahoo! Directory, Yahoo! Mail, Yahoo! News, advertising, online mapping (Yahoo! Maps), video sharing (Yahoo! Video), and social media websites and services. It is one of the largest websites in the United States.
Yahoo! was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 1, 1995. On January 13, 2009, Yahoo! appointed Carol Bartz, former executive chairperson of Autodesk, as its new chief executive officer and a member of the board of directors. On September 6, 2011, Bartz was removed from her position at Yahoo! (via phone call), and CFO Tim Morse was named as Interim CEO of the company.
Bartz was brought into Yahoo in January 2009 to turn the company around after it balked at Microsoft’s $44.6 billion takeover offer. Since then, she’s trimmed costs through aggressive job cuts and shuttered a number of businesses, including Zimbra, Geocities and Delicious.
