YouTube is a video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees in February 2005. In November 2006, it was bought by Google for US$1.65 billion. YouTube now operates as one of Google's subsidiaries. The site allows users to upload, view, and share videos, and it makes use of Adobe Flash Video and HTML5 technology to display a wide variety of user-generated and corporate media video. Available content includes video clips, TV clips, music videos, and other content such as video blogging, short original videos, and educational videos.
Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program. Unregistered users can watch videos, and registered users can upload videos to their channels. Videos considered to contain potentially offensive content are available only to registered users affirming themselves to be at least 18 years old.

YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, who were all early employees of PayPal. Hurley had studied design at Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign.
According to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that YouTube was founded after a dinner party "was probably very strengthened by marketing ideas around creating a story that was very digestible".
Karim said the inspiration for YouTube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site. Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not.
YouTube began as a venture-funded technology startup, primarily from a $11.5 million investment by Sequoia Capital between November 2005 and April 2006. YouTube's early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California. The domain name
www.youtube.com was activated on February 14, 2005, and the website was developed over the subsequent months.
YouTube offered the public a beta test of the site in May 2005, six months before the official launch in November 2005. The site grew rapidly, and in July 2006 the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day. According to data published by market research company comScore, YouTube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010.
YouTube says that 300 hours of new videos are uploaded to the site every minute, three times more than one year earlier and that around three quarters of the material comes from outside the U.S. The site has 800 million unique users a month. It is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. Alexa ranks YouTube as the third most visited website on the Internet, behind Google and Facebook.
The choice of the name
www.youtube.com led to problems for a similarly named website,
www.utube.com. The site's owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to
Google does not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing. In June 2008, a Forbes magazine article projected the 2008 revenue at $200 million, noting progress in advertising sales. In January 2012, it was estimated that visitors to YouTube spent an average of 15 minutes a day on the site, in contrast to the four or five hours a day spent by a typical U.S. citizen watching television.
YouTube entered into a marketing and advertising partnership with NBC in June 2006. In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for US viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney. In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners. In January 2010, YouTube introduced an online film rentals service, which is available only to users in the US, Canada and the UK as of 2010. The service offers over 6,000 films.
In March 2010, YouTube began free streaming of certain content, including 60 cricket matches of the Indian Premier League. According to YouTube, this was the first worldwide free online broadcast of a major sporting event.
On March 31, 2010, the YouTube website launched a new design, with the aim of simplifying the interface and increasing the time users spend on the site. Google product manager Shiva Rajaraman commented: "We really felt like we needed to step back and remove the clutter." In May 2010, it was reported that YouTube was serving more than two billion videos a day, which it described as "nearly double the prime-time audience of all three major US television networks combined". In May 2011, YouTube reported in its company blog that the site was receiving more than three billion views per day. In January 2012, YouTube stated that the figure had increased to four billion videos streamed per day.
In April 2011, James Zern, a YouTube software engineer, revealed that 30% of videos accounted for 99% of views on the site.
In December 2011, YouTube launched a new version of the site interface, with the video channels displayed in a central column on the home page, similar to the news feeds of social networking sites. At the same time, a new version of the YouTube logo was introduced with a darker shade of red, the first change in design since October 2006.
In May 2013, YouTube launched a pilot program to begin offering some content providers the ability to charge $0.99 per month or more for certain channels, but the vast majority of its videos would remain free to view.
In February 2015, YouTube announced the launch a new app specifically for use by children visiting the site, called YouTube Kids. It allows parental controls and restrictions on who can upload content, and will initially be available on Google's Android devices only.
In January 2010, YouTube launched an experimental version of the site that uses the built-in multimedia capabilities of web browsers supporting the HTML5 standard. This allows videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site has a page that allows supported browsers to opt into the HTML5 trial. Only browsers that support HTML5 Video using the H.264 or WebM formats can play the videos, and not all videos on the site are available.
YouTube experimented with Dynamic Adaptive Streaming over HTTP (MPEG-DASH), which is an adaptive bit-rate HTTP-based streaming solution optimizing the bitrate and quality for the available network. Currently they are using Adobe Dynamic Streaming for Flash.
All YouTube users can upload videos up to 15 minutes each in duration. Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, which requires verifying the account, normally through a mobile phone. When YouTube was launched in 2005, it was possible to upload long videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films. The 10-minute limit was increased to 15 minutes in July 2010. If an up-to-date browser version is used, videos greater than 20 GB can be uploaded.
YouTube accepts videos uploaded in most container formats, including .AVI, .MKV, .MOV, .MP4, DivX, .FLV, and .ogg and .ogv. These include video formats such as MPEG-4, MPEG, VOB, and .WMV. It also supports 3GP, allowing videos to be uploaded from mobile phones. Videos with progressive scanning or interlaced scanning can be uploaded, but for the best video quality, YouTube suggests interlaced videos be deinterlaced before uploading. All the video formats on YouTube use progressive scanning.
Quality and formats
YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263), with mono MP3 audio. In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. In March 2008, a high quality mode was added, which increased the resolution to 480×360 pixels.
In November 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9. With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels. YouTube has since lowered the maximum resolution to 3840×2160 pixels, which is twice as many pixels in both directions as 1080p.
In June 2014, YouTube introduced videos playing at 60 frames per second, in order to reproduce video games with a frame rate comparable to high-end graphics cards. The videos play back at a resolution of 720p or higher.
YouTube videos are available in a range of quality levels. The former names of standard quality (SQ), high quality (HQ) and high definition (HD) have been replaced by numerical values representing the vertical resolution of the video. The default video stream is encoded in the VP9 format with stereo Opus audio; if VP9/WebM is not supported in the browser/device or the browser's user agent reports Windows XP, then H.264/MPEG-4 AVC video with stereo AAC audio is used instead.

In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users can now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision.
YouTube offers users the ability to view its videos on web pages outside their website. Each YouTube video is accompanied by a piece of HTML that can be used to embed it on any page on the Web. This functionality is often used to embed YouTube videos in social networking pages and blogs. Users wishing to post a video discussing, inspired by or related to another user's video are able to make a "video response". On August 27, 2013, YouTube announced that it would remove video responses for being an underused feature. Embedding, rating, commenting and response posting can be disabled by the video owner.
YouTube does not usually offer a download link for its videos, and intends for them to be viewed through its website interface. A small number of videos, such as the weekly addresses by President Barack Obama, can be downloaded as MP4 files. Numerous third-party web sites, applications and browser plug-ins allow users to download YouTube videos. In February 2009, YouTube announced a test service, allowing some partners to offer video downloads for free or for a fee paid through Google Checkout. In June 2012, Google sent cease and desist letters threatening legal action against several websites offering online download and conversion of YouTube videos. In response, Zamzar removed the ability to download YouTube videos from its site. The default settings when uploading a video to YouTube will retain a copyright on the video for the uploader, but since July 2012 it has been possible to select a Creative Commons license as the default, allowing other users to reuse and remix the material if it is free of copyright.
Most modern smartphones are capable of accessing YouTube videos, either within an application or through an optimized website. YouTube Mobile was launched in June 2007, using RTSP streaming for the video. Not all of YouTube's videos are available on the mobile version of the site.
Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. According to GlobalWebIndex, YouTube was used by 35% of smartphone users between April and June 2013, making it the third most used app.
A TiVo service update in July 2008 allowed the system to search and play YouTube videos. In January 2009, YouTube launched "YouTube for TV", a version of the website tailored for set-top boxes and other TV-based media devices with web browsers, initially allowing its videos to be viewed on the PlayStation 3 and Wii video game consoles. In June 2009, YouTube XL was introduced, which has a simplified interface designed for viewing on a standard television screen. YouTube is also available as an app on Xbox Live. On November 15, 2012, Google launched an official app for the Wii, allowing users to watch YouTube videos from the Wii channel. An app is also available for Wii U and Nintendo 3DS, and videos can be viewed on the Wii U Internet Browser using HTML5. Google made YouTube available on the Roku player on December 17, 2013 and in October 2014, the Sony PlayStation 4.
On June 19, 2007, Google CEO Eric Schmidt was in Paris to launch the new localization system. The interface of the website is available with localized versions in 75 countries, one territory (Hong Kong) and a worldwide version.
The YouTube interface suggests which local version should be chosen on the basis of the IP address of the user. In some cases, the message "This video is not available in your country" may appear because of copyright restrictions or inappropriate content.
Access to YouTube was blocked in Turkey between 2008 and 2010, following controversy over the posting of videos deemed insulting to Mustafa Kemal Atatürk and some material offensive to Muslims. In October 2012, a local version of YouTube was launched in Turkey, with the domain
youtube.com.tr. The local version is subject to the content regulations found in Turkish law.
In March 2009, a dispute between YouTube and the British royalty collection agency PRS for Music led to premium music videos being blocked for YouTube users in the United Kingdom. The removal of videos posted by the major record companies occurred after failure to reach agreement on a licensing deal. The dispute was resolved in September 2009. In April 2009, a similar dispute led to the removal of premium music videos for users in Germany.
On November 12, 2014, YouTube announced the launch of Music Key, a subscription music streaming service, providing advertising-free playback of official music videos hosted by YouTube, along with background and offline playback on mobile platforms. Music Key is intended to integrate with and replace the existing Google Play Music "All Access" service.
YouTube has featured an April Fools prank on the site on April 1 of every year since 2008:
- 2008: All the links to the videos on the main page were redirected to Rick Astley's music video "Never Gonna Give You Up", a prank known as "Rickrolling".
- 2009: When clicking on a video on the main page, the whole page turned upside down. YouTube claimed that this was a new layout.
- 2010: YouTube temporarily released a "TEXTp" mode, which translated the colors in the videos to random upper case letters. YouTube claimed in a message that this was done in order to reduce bandwidth costs by $1 per second.
- 2011: The site celebrated its "100th anniversary" with a "1911 button" and a range of sepia-toned silent, early 1900s-style films, including "Flugelhorn Feline", a parody of Keyboard Cat.
- 2012: Clicking on the image of a DVD next to the site logo led to a video about "The YouTube Collection", an option to order every YouTube video for home delivery on DVD, videocassette, Laserdisc, or Betamax tapes. The spoof promotional video touted "the complete YouTube experience completely offline."
- 2013: YouTube teamed up with newspaper satire company The Onion to claim that the video sharing website was launched as a contest which had finally come to an end, and would announce a winner of the contest when the site went back up in 2023. A video of two presenters announcing the nominees streamed live for twelve hours.
- 2014: YouTube announced that it was responsible for the creation of all viral video trends, and revealed previews of upcoming memes, such as "Clocking", "Kissing Dad", and "Glub Glub Water Dance".
- 2015: Youtube added a music button to the video bar that played samples from "Sandstorm" by Darude. Additionally, when users searched for a song title, a message would appear saying "Did you mean: Darude - Sandstorm by Darude".
Both private individuals and large production companies have used YouTube to grow audiences. Independent content creators have built grassroots followings numbering in the thousands at very little cost or effort, while mass retail and radio promotion proved problematic. Concurrently, old media celebrities moved into the website at the invitation of a YouTube management that witnessed early content creators accruing substantial followings, and perceived audience sizes potentially larger than that attainable by television. While YouTube's revenue-sharing "Partner Program" made it possible to earn a substantial living as a video producer—its top five hundred partners each earning more than $100,000 annually—in 2012 CMU business editor characterized YouTube as "a free-to-use... promotional platform for the music labels". In 2013 Forbes' Katheryn Thayer asserted that digital-era artists' work must not only be of high quality, but must elicit reactions on the YouTube platform and social media. In 2013, videos of the 2.5% of artists categorized as "mega", "mainstream" and "mid-sized" received 90.3% of the relevant views on YouTube and Vevo. By early 2013 Billboard had announced that it was factoring YouTube streaming data into calculation of the Billboard Hot 100 and related genre charts.
Observing that face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution", TED curator Chris Anderson referred to several YouTube contributors and asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication". Anderson asserted that it's not far-fetched to say that online video will dramatically accelerate scientific advance, and that video contributors may be about to launch "the biggest learning cycle in human history." In education, for example, the Khan Academy grew from YouTube video tutoring sessions for founder Salman Khan's cousin into what Forbes' Michael Noer called "the largest school in the world", with technology poised to disrupt how people learn.
YouTube was awarded a 2008 George Foster Peabody Award, the website being described as a Speakers' Corner that "both embodies and promotes democracy." The Washington Post reported that a disproportionate share of YouTube's most subscribed channels feature minorities, contrasting with mainstream television in which the stars are largely white.
A Pew Research Center study reported the development of "visual journalism", in which citizen eyewitnesses and established news organizations share in content creation. The study also concluded that YouTube was becoming an important platform by which people acquire news.
YouTube has enabled people to more directly engage with government, such as in the CNN/YouTube presidential debates (2007) in which ordinary people submitted questions to U.S. presidential candidates via YouTube video, with a techPresident co-founder saying that Internet video was changing the political landscape. Describing the Arab Spring (2010- ), sociologist Philip N. Howard quoted an activist's succinct description that organizing the political unrest involved using "Facebook to schedule the protests, Twitter to coordinate, and YouTube to tell the world." In 2012, more than a third of the U.S. Senate introduced a resolution condemning Joseph Kony 16 days after the "Kony 2012" video was posted to YouTube, with resolution co-sponsor Senator Lindsey Graham remarking that the video "will do more to lead to (Kony's) demise than all other action combined."
Conversely, YouTube has also allowed government to more easily engage with citizens, the White House's official YouTube channel being the seventh top news organization producer on YouTube in 2012 and in 2013 a healthcare exchange commissioned Obama impersonator Iman Crosson's YouTube music video spoof to encourage young Americans to enroll in the Affordable Care Act (Obamacare)-compliant health insurance. In February 2014, U.S. President Obama held a meeting at the White House with leading YouTube content creators to not only promote awareness of Obamacare but more generally to develop ways for government to better connect with the "YouTube Generation". Whereas YouTube's inherent ability to allow presidents to directly connect with average citizens was noted, the YouTube content creators' new media savvy was perceived necessary to better cope with the website's distracting content and fickle audience.
TED curator Chris Anderson described a phenomenon by which geographically distributed individuals in a certain field share their independently developed skills in YouTube videos, thus challenging others to improve their own skills, and spurring invention and evolution in that field. Journalist Virginia Heffernan stated in The New York Times that such videos have "surprising implications" for the dissemination of culture and even the future of classical music.
The Legion of Extraordinary Dancers and the YouTube Symphony Orchestra selected their membership based on individual video performances. Further, the cybercollaboration charity video "We Are the World 25 for Haiti (YouTube edition)" was formed by mixing performances of 57 globally distributed singers into a single musical work, with The Tokyo Times noting the "We Pray for You" YouTube cyber-collaboration video as an example of a trend to use crowdsourcing for charitable purposes.
The anti-bullying It Gets Better Project expanded from a single YouTube video directed to discouraged or suicidal LGBT teens, that within two months drew video responses from hundreds including U.S. President Barack Obama, Vice President Biden, White House staff, and several cabinet secretaries. Similarly, in response to fifteen year old Amanda Todd's video "My story: Struggling, bullying, suicide, self harm", legislative action was undertaken almost immediately after her suicide to study the prevalence of bullying and form a national anti-bullying strategy.
The vast majority of videos on YouTube are free to view and supported by advertising. In May 2007, YouTube launched its Partner Program, a system based on AdSense which allows the uploader of the video to share the revenue produced by advertising on the site. YouTube typically takes 45 percent of the advertising revenue from videos in the Partner Program, with 55 percent going to the uploader. There are over a million members of the YouTube Partner Program. According to TubeMogul, in 2013 a pre-roll advertisement on YouTube (one that is shown before the video starts) cost advertisers on average $7.60 per 1000 views. Usually no more than half of eligible videos have a pre-roll advertisement, due to a lack of interested advertisers. Assuming pre-roll advertisements on half of videos, a YouTube partner would earn 0.5 X $7.60 X 55% = $2.09 per 1000 views in 2013.
In May 2013, YouTube introduced a trial scheme of 53 subscription channels with prices ranging from $0.99 to $6.99 a month. The move was seen as an attempt to compete with other providers of online subscription services such as Netflix and Hulu.
YouTube has a set of community guidelines aimed to reduce abuse of the site's features. Generally prohibited material includes sexually explicit content, videos of animal abuse, shock videos, content uploaded without the copyright holder's consent, hate speech, spam, and predatory behaviour. Despite the guidelines, YouTube has faced criticism from news sources for content in violation of these guidelines.
At the time of uploading a video, YouTube users are shown a message asking them not to violate copyright laws. Despite this advice, there are still many unauthorized clips of copyrighted material on YouTube. YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a DMCA takedown notice pursuant to the terms of the Online Copyright Infringement Liability Limitation Act. Three successful complaints for copyright infringement against a user account will result in the account and all of its uploaded videos being deleted.
Organizations including Viacom, Mediaset, and the English Premier League have filed lawsuits against YouTube, claiming that it has done too little to prevent the uploading of copyrighted material. Viacom, demanding $1 billion in damages, said that it had found more than 150,000 unauthorized clips of its material on YouTube that had been viewed "an astounding 1.5 billion times". YouTube responded by stating that it "goes far beyond its legal obligations in assisting content owners to protect their works".
During the same court battle, Viacom won a court ruling requiring YouTube to hand over 12 terabytes of data detailing the viewing habits of every user who has watched videos on the site. The decision was criticized by the Electronic Frontier Foundation, which called the court ruling "a setback to privacy rights". In June 2010, Viacom's lawsuit against Google was rejected in a summary judgment, with U.S. federal Judge Louis L. Stanton stating that Google was protected by provisions of the Digital Millennium Copyright Act. Viacom announced its intention to appeal the ruling.
On April 5, 2012, the United States Court of Appeals for the Second Circuit reinstated the case, allowing Viacom's lawsuit against Google to be heard in court again. On March 18, 2014, the lawsuit was settled after seven years with an undisclosed agreement.
In August 2008, a US court ruled in Lenz v. Universal Music Corp. that copyright holders cannot order the removal of an online file without first determining whether the posting reflected fair use of the material. The case involved Stephanie Lenz from Gallitzin, Pennsylvania, who had made a home video of her 13-month-old son dancing to Prince's song "Let's Go Crazy", and posted the 29-second video on YouTube.
In the case of Smith v. Summit Entertainment LLC, professional singer Matt Smith sued Summit Entertainment for the wrongful use of copyright takedown notices on YouTube. He asserted seven causes of action, and four were ruled in Smith's favor.
In April 2012, a court in Hamburg ruled that YouTube could be held responsible for copyrighted material posted by its users. The performance rights organization GEMA argued that YouTube had not done enough to prevent the uploading of German copyrighted music. YouTube responded by stating:
|“||We remain committed to finding a solution to the music licensing issue in Germany that will benefit artists, composers, authors, publishers and record labels, as well as the wider YouTube community.||”|
As of 2013, YouTube and GEMA have still not reached a licensing agreement. As a result, most videos containing copyrighted music have been blocked in Germany since 2009.
In April 2013, it was reported that Universal Music Group and YouTube have a contractual agreement that prevents content blocked on YouTube by a request from UMG from being restored, even if the uploader of the video files a DMCA counter-notice. When a dispute occurs, the uploader of the video has to contact UMG.
In June 2007, YouTube began trials of a system for automatic detection of uploaded videos that infringe copyright. The system was regarded by Google CEO Eric Schmidt as necessary for resolving lawsuits such as the one from Viacom, which alleged that YouTube profited from pirated content. The system, which became known as Content ID, creates an ID File for copyrighted audio and video material, and stores it in a database. When a video is uploaded, it is checked against the database, and flags the video as a copyright violation if a match is found.
When this occurs, the content owner has the choice of blocking the video to make it unviewable, tracking the viewing statistics of the video, or adding advertisements to the video. YouTube describes Content ID as "very accurate in finding uploads that look similar to reference files that are of sufficient length and quality to generate an effective ID File". Content ID accounts for over a third of the monetized views on YouTube.
An independent test in 2009 uploaded multiple versions of the same song to YouTube, and concluded that while the system was "surprisingly resilient" in finding copyright violations in the audio tracks of videos, it was not infallible. The use of Content ID to remove material automatically has led to controversy in some cases, as the videos have not been checked by a human for fair use. If a YouTube user disagrees with a decision by Content ID, it is possible to fill in a form disputing the decision. YouTube has cited the effectiveness of Content ID as one of the reasons why the site's rules were modified in December 2010 to allow some users to upload videos of unlimited length.
YouTube has also faced criticism over the offensive content in some of its videos. The uploading of videos containing defamation, pornography, and material encouraging criminal conduct is prohibited by YouTube's terms of service. Controversial content has included that pertaining to Holocaust denial and the Hillsborough disaster, in which 96 football fans from Liverpool were crushed to death in 1989.
YouTube relies on its users to flag the content of videos as inappropriate, and a YouTube employee will view a flagged video to determine whether it violates the site's terms of service. In July 2008, the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "proactive review of content should be standard practice for sites hosting user-generated content". YouTube responded by stating:
|“||We have strict rules on what's allowed, and a system that enables anyone who sees inappropriate content to report it to our 24/7 review team and have it dealt with promptly. We educate our community on the rules and include a direct link from every YouTube page to make this process as easy as possible for our users. Given the volume of content uploaded on our site, we think this is by far the most effective way to make sure that the tiny minority of videos that break the rules come down quickly. (July 2008)||”|
In October 2010, U.S. Congressman Anthony Weiner urged YouTube to remove from its website videos of imam Anwar al-Awlaki, saying that by hosting al-Awlaki's messages, "We are facilitating the recruitment of homegrown terror". British security minister Pauline Neville-Jones commented: "These Web sites would categorically not be allowed in the U.K. They incite cold-blooded murder, and as such are surely contrary to the public good." YouTube pulled some of the videos in November 2010, stating they violated the site's guidelines prohibiting "dangerous or illegal activities such as bomb-making, hate speech and incitement to commit violent acts", or came from accounts "registered by a member of a designated foreign terrorist organization". In December 2010, YouTube added "promotes terrorism" to the list of reasons that users can give when flagging a video as inappropriate.
Most videos enable users to leave comments, and these have attracted attention for the negative aspects of both their form and content. In 2006, Time praised Web 2.0 for enabling "community and collaboration on a scale never seen before", and added that YouTube "harnesses the stupidity of crowds as well as its wisdom. Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred". The Guardian in 2009 described users' comments on YouTube as:
|“||Juvenile, aggressive, misspelled, sexist, homophobic, swinging from raging at the contents of a video to providing a pointlessly detailed description followed by a LOL, YouTube comments are a hotbed of infantile debate and unashamed ignorance – with the occasional burst of wit shining through.||”|
In September 2008, The Daily Telegraph commented that YouTube was "notorious" for "some of the most confrontational and ill-formed comment exchanges on the internet", and reported on YouTube Comment Snob, "a new piece of software that blocks rude and illiterate posts". The Huffington Post noted in April 2012 that finding comments on YouTube that appear "offensive, stupid and crass" to the "vast majority" of the people is hardly difficult.
On November 6, 2013, Google implemented a new comment system that requires all YouTube users to use a Google+ account in order to comment on videos and making the comment system Google+ oriented. The changes are in large part an attempt to address the frequent criticisms of the quality and tone of YouTube comments. They give creators more power to moderate and block comments, and add new sorting mechanisms to ensure better, more relevant discussions appear at the top. The new system restored the ability to include URLs in comments, which had previously been removed due to problems with abuse.
YouTube co-founder Jawed Karim posted the question, "why the fuck do I need a google+ account to comment on a video?" on his YouTube channel to express his negative opinion of the change. The official YouTube announcement received 20,097 "thumbs down" votes and generated more than 32,000 comments in two days. Writing in the Newsday blog Silicon Island, Chase Melvin noted that "Google+ is nowhere near as popular a social media network as Facebook, but it's essentially being forced upon millions of YouTube users who don't want to lose their ability to comment on videos" and "Discussion forums across the Internet are already bursting with outcry against the new comment system". In the same article Melvin goes on to say:
|“||Perhaps user complaints are justified, but the idea of revamping the old system isn't so bad.
Think of the crude, misogynistic and racially-charged mudslinging that has transpired over the last eight years on YouTube without any discernible moderation. Isn't any attempt to curb unidentified libelers worth a shot? The system is far from perfect, but Google should be lauded for trying to alleviate some of the damage caused by irate YouTubers hiding behind animosity and anonymity.
In December 2012, two billion views were removed from the view counts of Universal and Sony music videos on YouTube, prompting a claim by The Daily Dot that the views had been deleted due to a violation of the site's terms of service, which ban the use of automated processes to inflate view counts. This was disputed by Billboard, which said that the two billion views had been moved to Vevo, since the videos were no longer active on YouTube.
Censorship and filtering
YouTube is blocked for a variety of reasons, including:
- limiting public exposure to content that may ignite social or political unrest;
- preventing criticism of a ruler, government, government officials, religion, or religious leaders;
- violations of national laws, including:
- preventing access to videos judged to be inappropriate for youth;
- reducing distractions at work or school; and
- reducing the amount of network bandwidth used.
In some countries, YouTube is completely blocked, either through a long term standing ban or for more limited periods of time such as during periods of unrest, the run-up to an election, or in response to upcoming political anniversaries. In other countries access to the website as a whole remains open, but access to specific videos is blocked. In cases where the entire site is banned due to one particular video, YouTube will often agree to remove or limit access to that video in order to restore service.
Businesses, schools, government agencies, and other private institutions often block social media sites, including YouTube, due to bandwidth limitations and the site's inevitable potential for distraction.
Several countries have blocked access to YouTube:
- Iran temporarily blocked access on December 3, 2006, to YouTube and several other sites, after declaring them as violating social and moral codes of conduct. The YouTube block came after a video was posted online that appeared to show an Iranian soap opera star having sex. The block was later lifted and then reinstated after Iran's 2009 presidential election. In 2012, Iran reblocked access, along with access to Google, after the controversial film Innocence of Muslims' trailer was released on YouTube.
- Thailand blocked access between 2006 and 2007 due to offensive videos relating to King Bhumibol Adulyadej.
- Some Australian state education departments block YouTube citing an inability to determine what sort of video material might be accessed.
- China blocked access from October 15, 2007, to March 22, 2008, and again starting on March 24, 2009. Access remains blocked.
- Morocco blocked access in May 2007, possibly as a result of videos critical of Morocco's actions in Western Sahara. YouTube became accessible again on May 30, 2007, after Maroc Telecom unofficially announced that the denied access to the website was a mere "technical glitch".
- Turkey blocked access between 2008 and 2010 after controversy over videos deemed insulting to Mustafa Kemal Atatürk. In November 2010, a video of the Turkish politician Deniz Baykal caused the site to be blocked again briefly, and the site was threatened with a new shutdown if it did not remove the video. During the two and a half year block of YouTube, the video-sharing website remained the eighth most-accessed site in Turkey. In 2014, Turkey blocked the access for the second time, after "a high-level intelligence leak."
- Pakistan blocked access on February 23, 2008, because of "offensive material" towards the Islamic faith, including display of the Danish cartoons of Muhammad. This led to a near global blackout of the YouTube site for around two hours, as the Pakistani block was inadvertently transferred to other countries. On February 26, 2008, the ban was lifted after the website had removed the objectionable content from its servers at the request of the government. Many Pakistanis circumvented the three-day block by using virtual private network software. In May 2010, following the Everybody Draw Mohammed Day, Pakistan again blocked access to YouTube, citing "growing sacrilegious content". The ban was lifted on May 27, 2010, after the website removed the objectionable content from its servers at the request of the government. However, individual videos deemed offensive to Muslims posted on YouTube will continue to be blocked. Pakistan again placed a ban on YouTube in September 2012, after the site refused to remove the film Innocence of Muslims, with the ban still in operation as of September 2013.
- Turkmenistan blocked access on December 25, 2009, for unknown reasons. Other websites, such as LiveJournal were also blocked.
- Libya blocked access on January 24, 2010, because of videos that featured demonstrations in the city of Benghazi by families of detainees who were killed in Abu Salim prison in 1996, and videos of family members of Libyan leader Muammar Gaddafi at parties. The blocking was criticized by Human Rights Watch. In November 2011, after the Libyan Civil War, YouTube was once again allowed in Libya.
- Afghanistan, Bangladesh, Russia, and Sudan blocked access in September 2012 following controversy over a 14-minute trailer for the film Innocence of Muslims which had been posted on the site.
- In Libya and Egypt, the Innocence of Muslims trailer was blamed for violent protests in September 2012. YouTube stated that "This video—which is widely available on the Web—is clearly within our guidelines and so will stay on YouTube. However, given the very difficult situation in Libya and Egypt we have temporarily restricted access in both countries."
Music Key licensing
In May 2014, prior to the launch of YouTube's subscription-based Music Key service, the independent music trade organization Worldwide Independent Network alleged that YouTube was using non-negotiable contracts with independent labels that were "undervalued" in comparison to other streaming services, and that YouTube would block all music content from labels who do not reach a deal to be included on the paid service. In a statement to the Financial Times in June 2014, Robert Kyncl confirmed that YouTube would block the content of labels who do not negotiate deals to be included in the paid service "to ensure that all content on the platform is governed by its new contractual terms." Stating that 90% of labels had reached deals, he went on to say that "while we wish that we had [a] 100% success rate, we understand that is not likely an achievable goal and therefore it is our responsibility to our users and the industry to launch the enhanced music experience." The Financial Times later reported that YouTube had reached an aggregate deal with Merlin Network—a trade group representing over 20,000 independent labels, for their inclusion in the service. However, YouTube itself has not confirmed the deal.
