Yahoo operates a portal that provides the latest news, entertainment, and sports information. The
portal also gives users access to other Yahoo services like Yahoo Mail, Yahoo Maps, Yahoo
Finance, Yahoo Groups and Yahoo Messenger.

Working with comScore, The New York Times found that Yahoo was able to collect far more
data about users than its competitors from its websites and advertising network. By one measure,
on average Yahoo had the potential in December 2007 to build a profile of 2,500 records per
month about each of its visitors.[23] Yahoo retains search requests for a period of 13 months.
However, in response to European regulators, Yahoo scrambles the IP address of users after
three months by deleting its last eight bits.[24]

On March 29, 2012, Yahoo announced that it would introduce a "Do Not Track" feature that
summer, allowing users to opt out of web-visit tracking and customized ads.[25]

According to a 2008 article in Computerworld, Yahoo has a 2-petabyte, specially built data
warehouse that it uses to analyze the behavior of its half-billion Web visitors per month,
processing 24 billion daily events.[26] In contrast the US Internal Revenue Service (IRS) database
of all US taxpayers weighs in at only 150 terabytes.[26]

Communication

Yahoo provides Internet communication services such as Yahoo Messenger and Yahoo Mail. As
of May 2007, its e-mail service would offer unlimited storage.[27]
Yahoo provided social networking services and user-generated content, including products such
as My Web, Yahoo Personals, Yahoo 360°, Delicious, Flickr, and Yahoo Buzz. Yahoo closed
Yahoo Buzz, MyBlogLog, and numerous other products on April 21, 2011.[28]

Yahoo Photos was closed on September 20, 2007, in favor of Flickr. On October 16, 2007,
Yahoo announced that it would discontinue Yahoo 360°, including bug repairs; the company
explained that in 2008 it would instead establish a "universal profile" similar to the Yahoo Mash
experimental system.[29]

Content

Yahoo partners with numerous content providers in products such as Yahoo Sports, Yahoo
Finance, Yahoo Music, Yahoo Movies, Yahoo Weather, Yahoo News, Yahoo Answers and
Yahoo Games to provide news and related content. Yahoo provides a personalization service,
My Yahoo!, which enables users to combine their favorite Yahoo features, content feeds and
information onto a single page.

On March 31, 2008, Yahoo launched Shine, a site tailored for women seeking online information
and advice between the ages of 25 and 54.[30]

Co-branded Internet services

Yahoo developed partnerships with broadband providers such as AT&T Inc. (via BellSouth &
SBC), Verizon Communications, Rogers Communications and British Telecom, offering a range
of free and premium Yahoo content and services to subscribers.[specify][vague][citation needed]
