1. Face book is a social networking site and website, launched in February 2004, operated and
privately owned by Face Book Inc.
Mark Zuckerberg wrote Facemash, the predecessor to Face book, on October 28, 2003, while
attending Harvard as a sophomore.
Zuckerberg hacked into the protected areas of Harvard's computer network and copied the
houses' private dormitory ID images.
Though individual houses had been issuing their own paper face books since the mid-1980s.
Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.
Face book was incorporated in mid-2004, and the entrepreneur SEAN PARKER, who had been
informally advising Zuckerberg, became the company's president.
In March 2004, Face book expanded to Stanford, Columbia, and Yale It soon opened to the
other Ivy League schools, Boston University, New York University, MIT, and gradually most
universities in Canada and the United States.

2. Face book launched a high-school version in September 2005, which Zuckerberg called the next
logical step.
Face book later expanded membership eligibility to employees of several companies,
including Apple Inc. and Microsoft. Face book was then opened on September 26, 2006, to
everyone of age 13 and older with a valid email address.
On October 24, 2007, Microsoft announced that it had purchased a 1.6% share of Face book for
$240 million, giving Face book a total implied value of around $15 billion. Microsoft's purchase
included rights to place international ads on Face book.
In October 2008, Face book announced that it would set up its international headquarters
in Dublin, Ireland.
In March 2011 it was reported that Face book removes approximately 20,000 profiles from the

6. "Friending" someone is the act of sending
them a friend request on Face book. Once the
friend request is set, the two people are both
Face book friends until and unless the receiving
party accepts the friend request. In addition to
accepting the request, the user has the option
of declining the friend request or hiding it using
the "Not Now" feature. Deleting a friend request
removes the request, but does allow the sender
to resend it in the future. The "Not Now" feature
hides the request but does not delete it, allowing
the receiver to revisit the request at a later
date.
It is also possible to remove a user from
one's friends, which is referred to as "un-
Friending" by Face book. Many Face book
users also refer to the process as "de-
friending ".“ Unfriend" was New Oxford
American Dictionary’s word of the year in
2009.

7.  On August 13, 2010, Face book
launched a new service called "Face
book Live", a live streaming video
channel that is intended to keep Face
book users updated to what is
happening on the social
networking site. The service, powered
by Live stream, will feature videos from
Face book staff members and celebrity
interviews, but is not designed for Face
book users to showcase their own
videos.
The first official guest was America
Ferrera, the leading actress in the
television series Ugly Betty. She
discussed her new independent film The
Dry Land, that was being promoted
almost exclusively through social media
channels.

8. The "Like Button" is also available for use
on websites outside Face book: "When the
user clicks the Like button on [a] site, a story
appears in the user's friends' News Feed with
a link back to [the] website.
"Like" links are vulnerable to like jacking, a
form of click jacking that makes users "Like"
content they did not intend to.[29] An Israeli
couple named their child "Like" after the
Face book feature in 2011.
 lawsuit was filed in Los Angeles in 2010
claiming the Face book should not allow minors to
"like" advertising; Face book said the suit was
"completely without merit."[ Because websites
with a "Like Button" send IP address information
of all visitors to Face book

9. Since the website's founding, it has
allowed users to send messages to each
other. A Face book user can send a message
to any number of his/her friends at a time.
Deleting a message from one's inbox does
not delete it from the inbox of other
users, thus disabling a sender to redo a
message sent by him or her.
On November 15, 2010, Face book
announced a new "Face book Messages"
service. In a media event that day, CEO Mark
Zuckerberg said, "It's true that people will
be able to have a @face book.com email
addresses, but it's not email." The launch of
such a feature had been anticipated for
some time before the announcement, with
some calling it a "Gmail killer."

10. Face book allows different networks and groups
which many users can join. This is essentially
equivalent to control of a blog for the administrators.
However these blogs allow some additional controls.
Groups are used for discussions, events, etc. and
are a way of enabling a number of people to come
together online to share information and discuss
specific subjects.
A flag which indicates if the group was created prior
to launch of the current groups product in October
2010.
The members who have joined, recent news
contents, wall contents, photos, posted items, videos
and all associated comments of such items. In this
respect, groups are similar to "Like pages" (below) but
contain a different set of features. Groups are limited
to 300 groups per Face book customer.

11. Notifications of the more important
events, for example, someone sharing
a link on the user's wall or commenting
on a post the user previously
commented on, briefly appear for a
few seconds in the bottom left as a
popup message (if the user is online),
and a red counter is updated on the
toolbar at the top, thus allowing the
user to keep track of all the most
recent notifications.

12. On April 11, 2011, Face book launched a new
feature for photo tagging – people can tag
photos with a brand, product, company or
person’s Face book page, similar to the way
they tag their friends in photos.
In August 2011, Face book announced that it
would be adding a series of photo filters to its
mobile application.
Face book plans to unveil nearly a dozen
photo filters, which will be similar to
Instragram's grainy images.[Per last known
numbers, today in the world, highest number
of photos are hosted at Face book.

13. During the time that Face book released
its platform, it also released an
application of its own for sharing videos
on Face book.
Users can add their videos with the
service by uploading video, adding video
through Face book Mobile, and using a
webcam recording feature. Additionally,
users can "tag" their friends in videos
they add much like the way users can tag
their friends in photos, except the
location of the friend in the video is not
displayed.
 Users also have the option of video
messaging. Videos cannot be placed in
categories, whereas photos are sorted by
albums. Facebook Video can support up to
1080p format and even 4K resolution.

14. "Status updates" (also called as a
"status") allows users to post
messages for their friends to read.
In turn, friends can respond with
their own comments, as well as
clicking the "Like" button.
Timeline/Wall and is also noted in
the "Recently Updated" section of a
user's friend list. Originally, the
purpose of the feature was to allow
users to inform their friends of
their current "status," including
feelings,
In 2009, Face book added the
feature to tag certain friends (or
groups, etc.) within one's status
update by adding an @ character
before their name, turning the
friend's name into a link to their
profile and including the message on
the friend's wall.

15. Since December 15, 2011, a Timeline is the
new virtual space in which all the content of
every Face book user will be organized and
shown. Replacing the Face book Profile, in a
Timeline the photos, videos, and posts of any
given user will be categorized according to
the period of time in which they were
uploaded or created.
Posts and events are displayed along a
timeline that runs through the center of the
profile, with the option of adding events that
occurred prior to the user joining Face book
as well as "hiding" posts.[
Timeline was originally offered as an
option, but all users will be migrated to the
format on March 30, 2012.
