Yahoo! Inc. (NASDAQ: YHOO) is an American computer services company. It operates an Internet portal, the Yahoo! Directory and a host of other services including Yahoo! Mail. It was founded by Stanford graduate students Jerry Yang and David Filo in January of 1994 and incorporated on March 2, 1995. The company is headquartered in Sunnyvale, California.

According to Web trends companies Alexa Internet and Netcraft, Yahoo! is the most visited website on the Internet today with more than 412 million unique users. The global network of Yahoo! websites received 3.4 billion page views per day on average as of October 2005.

History:

Yahoo! started out as "Jerry's Guide to the World Wide Web", a web site featuring a directory of other sites, organized in a hierarchy (rather than a searchable index of pages). It was renamed "Yahoo!" shortly thereafter. "Yet Another Hierarchical Officious Oracle" is a backronym for this name, but Filo and Yang insist they selected the name because they liked the word's general definition, as in Gulliver's Travels by Jonathan Swift: "rude, unsophisticated, uncouth."[1] As the backronymed version of the name implies, it was not the first directory of its kind, but it was the first to become widely popular as "the" directory of the fledgling Web. Yahoo! itself first resided on Yang's student workstation, "Akebono", while the software was lodged on Filo's computer, "Konishiki", both named after famous sumo wrestlers. The "yet another" phrasing goes back at least to the Unix utility yacc, whose name is an acronym for "yet another compiler compiler".

Yahoo! had its initial public offering on April 12, 1996, raising $33.8 million, by selling 2.6 million shares at US$13 each.

As Yahoo!'s popularity has increased, so has the range of features it offers, making it a kind of one-stop shop for all the popular activities of the Internet. These now include: Yahoo! Mail, a Web-based e-mail service, Yahoo! Messenger, an instant messaging client, a very popular mailing list service (Yahoo! Groups), online gaming and chat, various news and information portals, online shopping and online auction facilities. Many of these are based at least in part on previously independent services, which Yahoo! has acquired - such as the popular GeoCities free Web-hosting service, Rocketmail, and various competing mailing list providers such as eGroups. Many of these take-overs were controversial and unpopular with users of the existing services, as Yahoo! often changed the relevant terms of service. An example of this is their claiming intellectual property rights for the content on their servers, which the original companies had not done.

At the pinnacle of the Internet boom in the year 2000, the cable news station CNBC reported that Yahoo! and eBay were discussing a 50/50 merger.[2], Although the merger never materialised the two companies decided to form a marketing/advertising alliance six years later in 2006. [3]

Yahoo! has partnerships with telecommunications and Internet providers - such as BT in the UK, Rogers in Canada, and AT&T, Verizon[4] and BellSouth in the US - to create content-rich broadband services to rival those offered by AOL. The company offers a branded credit card, Yahoo! Visa, through a partnership with Chase.

Beginning in late 2002, Yahoo! began to bolster its search services by acquiring relevant companies. In December 2002, Yahoo! acquired Inktomi, and in July 2003, it acquired Overture Services, Inc. and its subsidiaries AltaVista and AlltheWeb.

As of 2005 Yahoo!'s news message boards have gained something of a cult following. Attached to every story is a discussion board, yet rarely are the posts pertinent to the story. Often, the posts are deliberately outrageous, attempting to provoke angry responses which, in turn, lead to more offensive posts and so on.

In June 2005 Yahoo! acquired blo.gs, a service based on RSS feed aggregation, primarily from weblogs (hence the name), which produces a simple list (and also an RSS feed thereof) of freshly updated Weblogs, ordered according to recentness of update. blo.gs was the first Internet company hosted on a domain hack Yahoo! acquired, del.icio.us being the second.
