But as the latest controversy around PewDiePie illustrates, his jokes have failed to land with many, many YouTube users, and there’s growing frustration with YouTube for not doing more to combat the growth of extremism in its midst. Though its most recent move of simply erasing PewDiePew from its rosily optimistic look back at 2018 might temporarily help to create a positive public image, when considering the evolution of PewDiePie’s influence alongside his steady drift toward the far right, it’s increasingly difficult to look back and laugh.
In June 2007, YouTube began trials of a system for automatic detection of uploaded videos that infringe copyright. Google CEO Eric Schmidt regarded this system as necessary for resolving lawsuits such as the one from Viacom, which alleged that YouTube profited from content that it did not have the right to distribute.[333] The system, which was initially called "Video Identification"[334][335] and later became known as Content ID,[336] 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.[337] 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. By 2010, YouTube had "already invested tens of millions of dollars in this technology".[335] In 2011, YouTube described 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".[337] By 2012, Content ID accounted for over a third of the monetized views on YouTube.[338]

Much of YouTube's revenue goes to the copyright holders of the videos.[283] In 2010, it was reported that nearly a third of the videos with advertisements were uploaded without permission of the copyright holders. YouTube gives an option for copyright holders to locate and remove their videos or to have them continue running for revenue.[307] In May 2013, Nintendo began enforcing its copyright ownership and claiming the advertising revenue from video creators who posted screenshots of its games.[308] In February 2015, Nintendo agreed to share the revenue with the video creators.[309][310][311]
Controversial content has included material relating to Holocaust denial and the Hillsborough disaster, in which 96 football fans from Liverpool were crushed to death in 1989.[345][346] 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:
As the title says, my watch history keeps pausing on its own, and it's pissing me off. It's been happening for over a month now, sometimes, if I unpause it fast enough (within a day of it happening), if I refresh the page sometimes I get fully watched or partially watched Spanish music videos, Russian News Videos, etc. Iv'e made sure NO ONE else has access to my account besides me. Anyone know wtf is going on? I searched online but It seems as though I'm the only one having issues here. :/

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.[123] 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.[124] Embedding, rating, commenting and response posting can be disabled by the video owner.[125]
Absent substantive oversight by regulators, in the late 1960s the calls for change entered a new, more creative phase. A group calling itself Action for Children’s Television began advocating for specific changes to programming for young kids. The Corporation for Public Broadcasting was formed in 1968 with government dollars. At the same time, Children’s Television Workshop began producing Sesame Street, and the forerunner to PBS, National Educational Television, began distributing Mister Rogers’ Neighborhood. These shows were tremendously successful in creating genuinely educational television. By the time children’s programming got swept up into the growing cable industry, the big channels had learned a lot from the public model, which they incorporated into shows such as Dora the Explorer and Blue’s Clues.
Later that year, YouTube came under criticism for showing inappropriate videos targeted at children and often featuring popular characters in violent, sexual or otherwise disturbing situations, many of which appeared on YouTube Kids and attracted millions of views. The term "Elsagate" was coined on the Internet and then used by various news outlets to refer to this controversy.[366][367][368][369] On November 11, 2017, YouTube announced it was strengthening site security to protect children from unsuitable content. Later that month, the company started to mass delete videos and channels that made improper use of family friendly characters. As part as a broader concern regarding child safety on YouTube, the wave of deletions also targeted channels which showed children taking part in inappropriate or dangerous activities under the guidance of adults. Most notably, the company removed Toy Freaks, a channel with over 8.5 million subscribers, that featured a father and his two daughters in odd and upsetting situations.[370][371][372][370][373][374] According to analytics specialist SocialBlade, it earned up to £8.7 million annually prior to its deletion.[375]
YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital and an $8 million investment from Artis Capital Management between November 2005 and April 2006.[11][12] YouTube's early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California.[13] The domain name www.youtube.com was activated on February 14, 2005, and the website was developed over the subsequent months.[14] The first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo.[15] The video was uploaded on April 23, 2005, and can still be viewed on the site.[16] YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005.[17][18] Following a $3.5 million investment from Sequoia Capital in November, the site launched officially on December 15, 2005, by which time the site was receiving 8 million views a day.[19][20] 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.[21] 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.[22]
