In January 1994, Jerry Yang and David Filo were Electrical Engineering graduate students at Stanford University when they created a website named "David and Jerry's Guide to the World Wide Web".[3] David and Jerry's Guide to the World Wide Web was a directory of other web sites, organized in a hierarchy, as opposed to a searchable index of pages. In April 1994, "David and Jerry's Guide to the World Wide Web" was renamed "Yahoo!".[4][5] The yahoo.com domain was created on January 18, 1995.[6]
Yahoo! grew rapidly throughout the 1990s. Like many search engines and web directories, Yahoo! diversified into a Web portal. It also made many high-profile acquisitions. Its stock price skyrocketed during the dot-com bubble, Yahoo! stocks closing at an all-time high of $118.75 a share on 3 January 2000. However, after the dot-com bubble burst, it settled at a post-bubble low of $4.05 on 26 September 2001 (adjusted for splits).
In 2000, Yahoo! began using Google for search results. Over the next four years, it developed its own search technologies, which it began using in 2004. Yahoo! also revamped its mail service to compete with Google's Gmail in 2007. The company struggled through 2008, with several large layoffs.
In February 2008, Microsoft Corporation made an unsolicited bid to acquire Yahoo! for USD $44.6 billion. Yahoo! subsequently formally rejected the bid, claiming that it "substantially undervalues" Yahoo! and was not in the interest of its shareholders. Three years later, Yahoo! had a stock market capitalization of USD $22.24 billion.[7] Carol Bartz replaced cofounder Jerry Yang in January 2009

[edit]Twitter slide leak on upcoming changes to Yahoo
On December 15, 2010, one day after Yahoo announced layoffs of 4% of its workers across their portfolio, MyBlogLog founder Eric Marcoullier posted a slide from a Yahoo employee on Twitter. The slide was visible during an employee-only strategy webcast indicating changes in Yahoo's offerings.[38]
The following services were in a column under "Sunset": Yahoo Picks, Altavista, MyM, AllTheWeb, Yahoo Bookmarks, Yahoo Buzz, del.icio.us, and MyBlogLog. Under "Merge" was: Upcoming, FoxyTunes, Yahoo Events, Yahoo People Search, Sideline, and FireEagle.
11 other properties were listed that Yahoo was interested in developing into feature sites within the portal to take the place of the "Sunset" and "Merge" vacancies, including the prior feature services (before the New Yahoo Mail was launched), were Yahoo Address Book, Calendar, and Notepad.[39] Yahoo's Chief Product Officer and Executive Vice President Blake Irving unofficially responded to the tweet implying that whoever sent him that particular slide is fired.[citation needed]
The blog on del.icio.us released a post by Chris Yeh after the leak, detailing that "Sunset" in their case doesn't necessarily mean they are closing down, and that other possibilities – including Delicious leaving Yahoo (through sale or spinoff) – are still on the table and that Delicious will not be closing down at this time; "We can only imagine how upsetting the news coverage over the past 24 hours has been to many of you. Speaking for our team, we were very disappointed by the way that this appeared in the press."
