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.[200] The interface of the YouTube website is available in 76 language versions, including Amharic, Albanian, Armenian, Bengali, Burmese, Khmer, Kyrgyz, Laotian, Mongolian, Persian and Uzbek, which do not have local channel versions. 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.[201][202] In October 2012, a local version of YouTube was launched in Turkey, with the domain The local version is subject to the content regulations found in Turkish law.[203] 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.[204] In April 2009, a similar dispute led to the removal of premium music videos for users in Germany.[205]
Among the specific findings, researchers demonstrated that Sesame Street improved children’s vocabulary, regardless of their parents’ education or attitudes. Another study found that regular adult TV stunted vocabulary development, while high-quality educational programs accelerated language acquisition. The most fascinating study began in the 1980s, when a University of Massachusetts at Amherst team installed video cameras in more than 100 homes, and had those families and hundreds of others keep a written log of their media diet. Following up more than a decade later, researchers found that “viewing educational programs as preschoolers was associated with higher grades, reading more books, placing more value on achievement, greater creativity, and less aggression.” On the flip side, violent programming led to lower grades among girls, in particular. The team was unequivocal about the meaning of these results: What kids watched was much more important than how much of it they watched. Or, as the researchers’ refutation of Marshall McLuhan’s famous aphorism went, “The medium is not the message: The message is.”
From the looks of things, YouTube's top-line growth hasn't been hurt much by worries among some companies -- for example, Cisco Systems (CSCO) , which just announced it's halting its YouTube ad spend -- about the running of their ads against content they find to be inappropriate. It also doesn't appear to have been hurt badly by YouTube's attempts to appease such advertisers by "demonetizing" videos that its algorithms deem unsuitable for running ads against, or the backlash such actions have sparked among affected content creators.
Additionally, in response to PewDiePie’s rec of the E;R channel, its owner described PewDiePie as producing “redpilled content.” And it’s easy to see why. Before declaring in 2017 that he would stop making Nazi jokes, PewDiePie made a whole lot of Nazi jokes. Even since then, he’s produced a long line of “satirical” videos and commentary that his alt-right followers have praised as examples of his “dropping redpills” on the rest of his fans.
In order for a YouTuber to get paid for an ad, the viewer of their video must have Ad-Block turned off (meaning they will see all the ads on videos) and must watch at least 30 seconds of videos they could otherwise skip. Or, this will work if the viewer sees smaller ads like banner ads, according to YouTuber Mah-Dry-Bread. The money generated from the viewer watching these ads is split between YouTube and your channel.
On one side lies many overlapping subcultures that make up huge swaths of the YouTube populations: its tremendous gaming communities, including Let’s Play-ers, live streamers, machinima-style editors, and vloggers; its prank cultures and their overlap with stunt personalities like Jake and Logan Paul; and its increasingly insidious alt-right presence.
Some investors and others have renewed calls for more transparency from YouTube in light of accounting rules and recent questions raised by the Securities and Exchange Commission about its disclosures. They say YouTube has become a material part of Alphabet’s business and an important driver of its growth, warranting quarterly disclosure of its revenue, costs and profitability. Some investors are also arguing that the lack of disclosure around YouTube could potentially be undervaluing Alphabet.
Pakistan blocked access on February 23, 2008, because of "offensive material" towards the Islamic faith, including display of the Danish cartoons of Muhammad.[415] 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.[416][417] Many Pakistanis circumvented the three-day block by using virtual private network software.[418] In May 2010, following the Everybody Draw Mohammed Day, Pakistan again blocked access to YouTube, citing "growing sacrilegious content".[419] 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.[420][421] 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.[422] The ban was lifted in January 2016 after YouTube launched a Pakistan-specific version.[423]
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),[86][87] with mono MP3 audio.[88] In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones.[89] In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels.[90] 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.[91] 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.[92][93] In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels.[94] In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ).[95] HDR video can be encoded with the Rec. 2020 color space.[96]
The great thing about sponsorships is that you don’t have to give YouTube a cut. Plus, you can negotiate whatever contracts you want based on impressions and the size of your audience. In most cases, the amount of revenue you generate from sponsorships is substantially more than YouTube ad revenue. (Meanwhile, you can still generate ad revenue. So it’s like having two sources of income from the same video.)
In Libya and Egypt, the Innocence of Muslims trailer was blamed[by whom?] 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."[433][434]
The men know this with quantitative precision. YouTube analytics show exactly when a video’s audience falls off. ChuChu and other companies like it—whatever their larger philosophy—can see exactly what holds a toddler’s attention, moment by moment, and what causes it to drift. If a video achieves a 60 percent average completion rate, ChuChu knows it has a hit. Using these data doesn’t let it “crack the algorithm”; everyone has access to a version of these numbers. Instead, Chandar uses the analytics to tune his and other creators’ intuition about what works.
If you really love making video content, consider doing it as a side hustle – something to beef up your resume, find a creative outlet or boost your professional profile in the area about which you broadcast. When it comes to making it big on YouTube, "It's obviously becoming more challenging as there are more creators out there, and everyone is fighting for an audience," Vaught says. "But the barriers to entry are also lower."
On February 28, 2017, in a press announcement held at YouTube Space Los Angeles, YouTube announced the launch of YouTube TV, an over-the-top MVPD-style subscription service that would be available for United States customers at a price of US$35 per month. Initially launching in five major markets (New York City, Los Angeles, Chicago, Philadelphia and San Francisco) on April 5, 2017,[220][221] the service offers live streams of programming from the five major broadcast networks (ABC, CBS, The CW, Fox and NBC), as well as approximately 40 cable channels owned by the corporate parents of those networks, The Walt Disney Company, CBS Corporation, 21st Century Fox, NBCUniversal and Turner Broadcasting System (including among others Bravo, USA Network, Syfy, Disney Channel, CNN, Cartoon Network, E!, Fox Sports 1, Freeform, FX and ESPN). Subscribers can also receive Showtime and Fox Soccer Plus as optional add-ons for an extra fee, and can access YouTube Premium original content (YouTube TV does not include a YouTube Red subscription).[222][223]
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, as well as live streams, which requires verifying the account, normally through a mobile phone.[78][79] When YouTube was launched in 2005, it was possible to upload longer 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.[80] The 10-minute limit was increased to 15 minutes in July 2010.[81] In the past, it was possible to upload videos longer than 12 hours. Videos can be at most 128 GB in size.[78] Video captions are made using speech recognition technology when uploaded. Such captioning is usually not perfectly accurate, so YouTube provides several options for manually entering the captions for greater accuracy.[82]
But whereas Disney has long mined cultures around the world for legends and myths—dropping them into consumerist, family-friendly American formats—ChuChu’s videos are a different kind of hybrid: The company ingests Anglo-American nursery rhymes and holidays, and produces new versions with subcontinental flair. The characters’ most prominent animal friend is a unicorn-elephant. Nursery rhymes become music videos, complete with Indian dances and iconography. Kids of all skin tones and hair types speak with an Indian accent.

In a widely circulated essay last year, the artist James Bridle highlighted the many violent, odd, and nearly robotic children’s videos sitting in the vaults of YouTube. They didn’t seem made by human hands, he wrote, or at least not completely. Some were sadistic or sick. (After Bridle’s essay was published, YouTube undertook an effort to purge the site of “content that attempts to pass as family-friendly, but clearly is not,” and ultimately removed some of the disturbing videos the essay cited.) Others seemed like grab bags of keywords that had been successful for more professional operations: nursery rhymes, surprise eggs, finger family, learning colors. These were videos reverse engineered from whatever someone might enter into the YouTube search box. And though none of these videos has achieved the scale of ChuChu’s work, they definitely get seen, and are occasionally recommended to a child who has been happily watching something more virtuous.
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.[347] (July 2008)

On January 27, 2015, YouTube announced that HTML5 would be the default playback method on supported browsers. YouTube used to employ Adobe Dynamic Streaming for Flash,[76] but with the switch to HTML5 video now streams video using Dynamic Adaptive Streaming over HTTP (MPEG-DASH), an adaptive bit-rate HTTP-based streaming solution optimizing the bitrate and quality for the available network.[77]
