CONTENT
UGC

11.  User generated content (UGC) covers a range of media content available
in a range of modern communications technologies.
 It entered mainstream usage during 2005 having arisen in web publishing
and new media content production circles. Its use for a wide range of
applications, including problem processing, news, gossip and research,
reflects the expansion of media production through new technologies that
are accessible and affordable to the general public.
 All digital media technologies are included, such as question-answer
databases, digital video, blogging, podcasting, forums, review-sites, social
networking, mobile phone photography and wikis.
 In addition to these technologies, user generated content may also employ
a combination of open source, free software, and flexible licensing or
related agreements to further reduce the barriers to collaboration, skill-
building and discovery.
 Sometimes UGC can constitute only a portion of a website.

12.  The OECD has defined three central schools for UGC :
 Publication requirement: While UGC could be made by a user
and never published online or elsewhere, we focus here on the
work that is published in some context, be it on a publicly
accessible website or on a page on a social networking site only
accessible to a select group of people (eg, fellow university
students). This is a useful way to exclude email, two-way instant
messages and the like.
 Creative effort: of creative effort was put into creating the work or
adapting existing works to construct a new one; i.e. users must add
their own value to the work. UGC often also has a collaborative
element to it, as is the case with websites which users can edit
collaboratively. For example, merely copying a portion of a
television show and posting it to an online video website (an activity
frequently seen on the UGC sites) would not be considered UGC. If
a user uploads his/her photographs, however, expresses his/her
thoughts in a blog, or creates a new music video, this could be
considered UGC. Yet the minimum amount of creative effort is hard
to define and depends on the context.
 Creation outside of professional routines and practices: User
generated content is generally created outside of professional
routines and practices. It often does not have an institutional or a
commercial market context. In extreme cases, UGC may be
produced by non-professionals without the expectation of profit or

13.  The British Broadcasting Corporation set up a user generated content
team as a pilot in April 2005 with 3 staff. In the wake of the 7 July
2005 London bombings and the Buncefield oil depot fire, the team was
made permanent and was expanded, reflecting the arrival in the
mainstream of the 'citizen journalist'. After the Buncefield disaster the
BBC received over 5,000 photos from viewers. The BBC does not
normally pay for content generated by its viewers.
 In 2006 CNN launched CNN iReport, a project designed to bring user
generated news content to CNN. Its rival Fox News Channel launched its
project to bring in user-generated news, similarly titled "uReport". This
was typical of major television news organisations in 2005-2006, who
realised, particularly in the wake of the 7th July bombings, that citizen
journalism could now become a significant part of broadcast news. Sky
News, for example, regularly solicits for photographs and video from its
viewers.
 User generated content was featured in Time magazine's 2006 Person of
the Year, in which the person of the year was "you", meaning all of the
people who contribute to user generated media such as YouTube and
Wikipedia.

17. Player generated content.
 Player generated content is the concept of video
game content being created by the players of the game, as
opposed to being created by a game's publisher or author.
 Player generated content is common in tabletop role playing
games where a game master creates a narrative or
adventure for the other players to encounter. Interfaces for
player generated content has been attempted in various PC
games such as Neverwinter Nights and Counterstrike with
some success, though the editors to create usable levels
are often difficult for the average user.
 LittleBigPlanet provided one of the biggest breakthroughs
by delivering level design tools as a focal feature of the
game that were fast and approachable. With content shared
amongst the community in a centralized resource, a large
amount of creations were designed and shared by players
seamlessly within the game itself. A streamlined
communication system further encouraged content creation
by making distribution and playing with friends easy. So
integrated was the experience that players could use
custom shared objects in their own levels or even design
levels collaboratively with up to three other players

18.  Often UGC is partially or
totally monitored by website
administrators to avoid
offensive content or language,
copyright infringement issues, or
simply to determine if the
content posted is relevant to
the site's general theme.
 However, there has often been
little or no charge for
uploading user generated
content. As a result, the world's
data centers are now replete
