Little kids are responsible for billions of views on YouTube—pretending otherwise is irresponsible. In a small study, a team of pediatricians at Einstein Medical Center, in Philadelphia, found that YouTube was popular among device-using children under the age of 2. Oh, and 97 percent of the kids in the study had used a mobile device. By age 4, 75 percent of the children in the study had their own tablet, smartphone, or iPod. And that was in 2015. The sea change in children’s content that ChuChu and other new video makers have effected is, above all, profitable.
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.[339] 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.[340] If a YouTube user disagrees with a decision by Content ID, it is possible to fill in a form disputing the decision.[341] Prior to 2016, videos weren't monetized until the dispute was resolved. Since April 2016, videos continue to be monetized while the dispute is in progress, and the money goes to whoever won the dispute.[342] Should the uploader want to monetize the video again, they may remove the disputed audio in the "Video Manager".[343] 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.[344]
In 2013, YouTube introduced an option for channels with at least a thousand subscribers to require a paid subscription in order for viewers to watch videos.[300][301] In April 2017, YouTube set an eligibility requirement of 10,000 lifetime views for a paid subscription.[302] On January 16, 2018, the eligibility requirement for monetization was changed to 4,000 hours of watchtime within the past 12 months and 1,000 subscribers.[302] The move was seen as an attempt to ensure that videos being monetized did not lead to controversy, but was criticized for penalizing smaller YouTube channels.[303]
In new year, Ryan Zinke, the Secretary of the Interior, seemed certain to catapult into that top tier of political nemeses for Democrats. Like Pruitt, Zinke excels at generating bizarre scandals; also like Pruitt, his own heroic vision of himself seems to survive any amount of bad press. House Democrats, salivating over their new oversight power, had already promised to subpoena Zinke over a number of issues, including a sweetheart $300-million contract for electricity in Puerto Rico that he allegedly gave to a small power company based in his home state of Montana.

There are over a million members of the YouTube Partner Program.[298] 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.[299]

YouTube's still-rapid viewing growth -- driven by smartphones and to an extent connected TVs -- has a lot to do with its revenue momentum. At last week's NewFronts online video ad event, YouTube disclosed it now had over 1.8 billion monthly logged-in viewers, up from 1.5 billion as of last June. And back in February 2017, YouTube said it was seeing over a billion hours per day of viewing -- that's about three times what Netflix (NFLX) witnessed on a record-breaking day in January, and 10 times what YouTube saw back in 2012.
As an advertiser on YouTube, you're populating your YouTube channel with video advertisements made by you. The difference between YouTube ads and, say, TV commercials, is that you get to show YouTube ads to more specific and often more engaged audience segments. You'll pay YouTube to host your ads on other, highly watched YouTube channels that appeal to the same viewership you're targeting.
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 behavior.[312] Despite the guidelines, YouTube has faced criticism from news sources for content in violation of these guidelines.
In a video posted on July 21, 2009,[112] YouTube software engineer Peter Bradshaw announced that YouTube users could 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.[113][114][115] 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.[116] The feature set has since been reduced, and 3D feature currently only supports red/cyan anaglyph with no side-by-side support.

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]
This might not exactly seem like a tragedy. After all, Americans watch a lot of TV. By the time Nielsen began recording how much time Americans spent in front of TV screens in 1949–50, each household was already averaging four hours and 35 minutes a day. That number kept going up, passing six hours in 1970–71, seven hours in 1983–84, all the way up to eight hours in 2003–04. Viewing finally peaked at eight hours and 55 minutes in 2009–10. Since then, the numbers have been gliding downward, with the most recent data showing Americans’ viewing habits edging under eight hours a day for the first time since George W. Bush’s presidency.

On my last day in the ChuChu offices, Krishnan related a parable to me from the Mahābhārata, a Sanskrit epic. A prince wants to be known as generous, so the god Krishna decides to put him to the test: He creates two mountains of gold and tells the prince to give it all away in 24 hours. The prince begins to do so, parceling it out to people he thinks need it. But as the day ends he’s hardly made a dent in the mountains. So Krishna calls another prince and tells him he has just five minutes to give away the gold. This prince sees two people walking along, goes right over to them, and gives each a mountain. Just like that, the job is done. The moral is unsettling, but simple: Don’t impose limits on your generosity.

YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, who were all early employees of PayPal.[6] 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.[7] 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".[8]
