<!-- History -->In October 2006, 18 months after posting its first video and 10 months after its official launch, YouTube was bought by Google for $1.65&nbsp;billion.<ref>{{Cite news |date=February 1, 2016 |title=How did Google become the world's most valuable company? |language=en-GB |work=BBC News |url=https://www.bbc.com/news/business-35460398 |access-date=May 26, 2021}}</ref> Google's ownership of YouTube expanded the site's business model, expanding from generating revenue from advertisements alone, to offering paid content such as movies and exclusive content produced by YouTube. It also offers [[YouTube Premium]], a paid subscription option for watching content without ads. YouTube also approved creators to participate in Google's [[Google AdSense|AdSense]] program, which seeks to generate more revenue for both parties. YouTube reported revenue of $19.8 billion in 2020.<ref>{{Cite web|title=YouTube global advertising revenues per quarter 2021|url=https://www.statista.com/statistics/289657/youtube-global-quarterly-advertising-revenues/|access-date=2022-01-31|website=Statista|language=en}}</ref> In 2021, YouTube's annual advertising revenue increased to $28.8 billion.<ref>{{Cite web |last=Weprin |first=Alex |date=2022-02-01 |title=YouTube Ad Revenue Tops $8.6B, Beating Netflix in the Quarter |url=https://www.hollywoodreporter.com/business/digital/youtube-ad-revenue-tops-8-6b-beating-netflix-in-the-quarter-1235085391/ |access-date=2022-06-11 |website=The Hollywood Reporter |language=en-US}}</ref>

<!-- Content and operations -->Since its purchase by Google, YouTube has expanded beyond the core website into [[mobile app]]s, network television, and the [[Interoperability|ability to link]] with other platforms. Video categories on YouTube include [[music video]]s, [[video clip]]s, [[news]], [[short film]]s, [[feature film]]s, [[documentary film|documentaries]], audio recordings, [[trailer (promotion)|movie trailers]], [[teaser (trailer)|teasers]], [[live stream]]s, [[vlog]]s, and more. Most content is [[user-generated content|generated by individuals]], including collaborations between [[YouTuber]]s and corporate sponsors. Established media corporations such as [[The Walt Disney Company|Disney]], [[Paramount Global|Paramount]], and [[Warner Bros. Discovery]] have also created and expanded their corporate YouTube channels to advertise to a larger audience.

<!-- Impact and reception -->YouTube has had an [[Social impact of YouTube|unprecedented social impact]], influencing popular culture, internet trends, and creating multimillionaire celebrities. Despite all its growth and success, YouTube has been widely criticized. Criticism of YouTube includes the website being used to facilitate the spread of [[misinformation]], [[YouTube copyright issues|copyright issues]], [[YouTube and privacy|routine violations of its users' privacy]], [[Censorship of YouTube|enabling censorship]], and endangering [[child protection|child safety and wellbeing]].

===Founding and initial growth (2005–2006)===
[[File:Youtube founders.jpg|thumb|upright=1.8|From left to right: [[Chad Hurley]], [[Steve Chen]], and [[Jawed Karim]], the founders of YouTube]]

YouTube was founded by [[Steve Chen]], [[Chad Hurley]], and [[Jawed Karim]]. The trio were early employees of [[PayPal]], which left them enriched after the company was bought by [[eBay]].<ref name=":7" /> Hurley had studied design at the [[Indiana University of Pennsylvania]], and Chen and Karim studied [[computer science]] together at the [[University of Illinois at Urbana–Champaign]].<ref>{{Cite web|date=October 11, 2006|title=YouTube founders now superstars|url=https://www.smh.com.au/technology/youtube-founders-now-superstars-20061011-gdokrc.html|access-date=March 18, 2021|website=The Sydney Morning Herald|language=en}}</ref>

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 remarked 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".<ref name="YouTube gurus">{{Cite magazine|last=Cloud|first=John|date=December 25, 2006|title=The YouTube Gurus|url=https://content.time.com/time/magazine/article/0,9171,1570795,00.html|magazine=Time|access-date=March 26, 2017}}</ref>

Karim said the inspiration for YouTube first came from the [[Super Bowl XXXVIII halftime show controversy]] when [[Janet Jackson]]'s breast was briefly exposed by [[Justin Timberlake]] during the halftime show. Karim could not easily find video clips of the incident and the [[2004 Indian Ocean earthquake and tsunami|2004 Indian Ocean Tsunami]] online, which led to the idea of a video sharing site.<ref>{{cite web|first=Jim|last=Hopkins|title=Surprise!

Contrary to popular belief, YouTube was not the first video-sharing site on the Internet; [[Vimeo]] was launched in November 2004, though that site remained a side project of its developers from [[CollegeHumor]] at the time and did not grow much, either.<ref name="fortune vimeo">{{cite web|url = https://fortune.com/2011/02/23/how-vimeo-became-hipster-youtube/ | title = How Vimeo became hipster YouTube | first = John Patrick | last= Pullen | date = February 23, 2011 | access-date = May 8, 2020 | work = [[Fortune (magazine)|Fortune]] }}</ref> The week of YouTube's launch, NBC-Universal's ''[[Saturday Night Live]]'' ran a skit "[[Lazy Sunday (The Lonely Island song)|Lazy Sunday]]" by [[The Lonely Island]].

==== YouTube public dislike count removal (2021–present) ====
After testing earlier in 2021, YouTube removed public display of dislike counts on videos in November 2021, claiming the reason for the removal was, based on its internal research, that users often used the dislike feature as a form of [[cyberbullying]] and [[vote brigading|brigading]].<ref name="BBC YouTube dislikes">{{cite web|title=YouTube removing dislike 'discourages trolls' but 'unhelpful for users'|url=https://www.bbc.co.uk/news/newsbeat-59264070|website=BBC News|date=November 12, 2021|access-date=November 30, 2021}}</ref> While some users praised the move as a way to discourage [[Internet troll|trolls]], others felt that hiding dislikes would make it harder for viewers to recognize clickbait or unhelpful videos, and that other features already existed for creators to limit bullying.

At launch in 2005, viewing YouTube videos on a personal computer required the [[Adobe Flash Player]] plug-in to be installed in the browser.<ref>{{cite news|title=Flash moves on to smart phones |publisher=BBC |url=https://news.bbc.co.uk/1/hi/8287239.stm |access-date=November 30, 2009 |date=October 5, 2009 |first=Jonathan |last=Fildes}}</ref> In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the [[HTML5]] standard.<ref name=":10">{{Cite web|last=Protalinski|first=Emil|date=January 27, 2015|title=YouTube ditches Flash for HTML5 video by default|url=https://venturebeat.com/2015/01/27/youtube-ditches-flash-for-html5-video-by-default/|access-date=May 5, 2021|website=VentureBeat|language=en-US}}</ref> This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed.<ref>{{cite web|url=https://www.downloadsquad.com/2009/11/08/html5-youtube-viewer-close-but-not-quite-there/ |title=HTML5 YouTube viewer: close, but not quite there |archive-url=https://web.archive.org/web/20091110003012/https://www.downloadsquad.com/2009/11/08/html5-youtube-viewer-close-but-not-quite-there/ |archive-date=November 10, 2009 |access-date=December 1, 2017}}</ref> On January 27, 2015, YouTube announced that HTML5 would be the default playback method on [[HTML5 video support|supported browsers]].<ref name=":10" /> With the switch to HTML5 video streams using [[Dynamic Adaptive Streaming over HTTP]] (MPEG-DASH), an HTTP-based adaptive bit-rate streaming solution optimizes the bitrate and quality for the available network.<ref>{{cite web|first=Rajeev |last=Tiwari |url=https://streamingcodecs.blogspot.hu/2013/01/mpeg-dash-support-in-youtube.html |title=Streaming Media and RTOS: MPEG-DASH Support in Youtube |publisher=Streamingcodecs.blogspot.hu |date=January 3, 2013 |access-date=March 13, 2014}}</ref>

The platform can serve videos at optionally lower resolution levels starting at 144p for smoothening playback in areas and countries with limited [[Internet speed]]s, improving compatibility, as well as for the preservation of limited cellular [[data plan]]s. The resolution setting can be adjusted automatically based on detected connection speed, as well as be set manually.<ref>{{Cite web|url=https://support.google.com/youtube/answer/91449?hl=en|title=Change the quality of your video – YouTube Help|website=support.google.com}}</ref><ref>{{cite web|last1=Conner|first1=Katie|date=July 1, 2019|title=Make YouTube videos sharper or load faster|url=https://www.cnet.com/how-to/change-the-quality-of-youtube-videos-on-your-phone-tv-and-laptop/|website=CNET|language=en}}</ref>

From 2008 to 2017, users could add "annotations" to their videos—such as pop-up text messages and hyperlinks, which allowed for [[interactive video]]s. By 2019 all annotations had been removed from videos, breaking some videos which depended on the feature. YouTube introduced standardized [[Widget (GUI)|widgets]] intended to replace annotations in a cross-platform manner, including "end screens" (a customizable array of thumbnails for specified videos displayed near the end of the video).<ref>{{Cite web|title=YouTube launches mobile-friendly "End Screens" feature to keep viewers watching more video|url=https://techcrunch.com/2016/10/26/youtube-launches-mobile-friendly-end-screens-feature-to-keep-viewers-watching-more-video/|access-date=January 14, 2019|website=TechCrunch|language=en-US}}</ref><ref>{{Cite web|last=Porter|first=Jon|date=November 27, 2018|title=YouTube annotations will disappear for good in January|url=https://www.theverge.com/2018/11/27/18114581/youtube-annotations-discontinued-january-2019|access-date=January 14, 2019|website=The Verge}}</ref><ref>{{Cite web|last=Statt|first=Nick|date=March 16, 2017|title=YouTube to discontinue video annotations because they never worked on mobile|url=https://www.theverge.com/2017/3/16/14953756/youtube-annotations-feature-discontinue-cards-end-screens|access-date=January 14, 2019|website=The Verge}}</ref>

In 2018, YouTube became an [[ISNI]] registry, and announced its intention to begin creating ISNI identifiers to uniquely identify the musicians whose videos it features.<ref name="ISNIYouTube1">{{cite web|title=YouTube Adopts ISNI ID for Artists & Songwriters|url=https://www.isni.org/content/youtube-adopts-isni-id-artists-songwriters|access-date=June 1, 2018|publisher=ISNI}}</ref> In 2020 it launched [[Video chapter|video chapters]] as a way to structure videos and improve navigation.

====Uploading====
All YouTube users can upload videos up to 15 minutes each in duration. Users can verify their account, normally through a mobile phone, to gain the ability to upload videos up to 12 hours in length, as well as produce live streams.<ref name="videolength">[https://www.google.com/support/youtube/bin/answer.py?answer=71673 "Upload videos longer than 15 minutes"] YouTube Help.

YouTube accepts the most common [[Digital container format|container formats]], including [[MPEG-4 Part 14|MP4]], [[Matroska]], [[Flash Video|FLV]], [[Audio Video Interleave|AVI]], [[WebM]], [[3GP and 3G2|3GP]], [[MPEG program stream|MPEG-PS]], and the [[QuickTime File Format]]. Some intermediate video formats (i.e., primarily used for professional video editing, not for final delivery or storage) are also accepted, such as [[Apple ProRes|ProRes]].<ref>{{Cite web|title=Supported YouTube file formats – YouTube Help|url=https://support.google.com/youtube/troubleshooter/2888402?hl=en|access-date=November 24, 2020|website=support.google.com}}</ref> YouTube provides recommended encoding settings.<ref>{{Cite web|title=Recommended upload encoding settings – YouTube Help|url=https://support.google.com/youtube/answer/1722171|access-date=November 24, 2020|website=support.google.com}}</ref>

Each video is identified by an eleven-character [[case-sensitive]] alphanumerical [[Base64#The URL applications|Base64]] string in the [[Uniform Resource Locator]] (URL) which can contain letters, digits, an underscore (<code>_</code>), and a dash (<code>-</code>).<ref>{{cite web |title=Here's Why YouTube Will Practically Never Run Out of Unique Video IDs |url=https://www.mentalfloss.com/article/77598/heres-why-youtube-will-never-run-out-unique-video-ids |website=www.mentalfloss.com |access-date=27 December 2021 |language=en |date=23 March 2016}}</ref>

In 2018, YouTube added a feature called ''Premiere'' which displays a notification to the user mentioning when the video will be available for the first time, like for a live stream but with a prerecorded video. When the scheduled time arrives, the video is aired as a live broadcast with a two-minute countdown. Optionally, a premiere can be initiated immediately.<ref>{{cite web|url=https://www.howtogeek.com/367588/what-are-youtube-premiers-and-how-do-you-use-them/|title=What are YouTube Premieres, and How Do You Use Them?}}</ref>

====Quality and formats====

YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 [[pixel]]s using the [[Sorenson codec|Sorenson Spark]] codec (a variant of [[H.263]]),<ref name="incomplete-h263">{{cite web|url=https://www.kaourantin.net/2005/08/quest-for-new-video-codec-in-flash-8.html |title=The quest for a new video codec in Flash 8 |first=Tinic |last=Uro |quote=We went this route before with Sorenson Spark which is an incomplete implementation of H.263 and it bit us badly when trying to implement certain solutions. |date=August 13, 2005 |access-date=January 27, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20090206142709/https://kaourantin.net/2005/08/quest-for-new-video-codec-in-flash-8.html |archive-date=February 6, 2009 }}</ref><ref name="flash-video">{{cite web|url=https://download.macromedia.com/f4v/video_file_format_spec_v10_1.pdf |title=Adobe Flash Video File Format Specification Version 10.1 |author=Adobe Systems Incorporated |page=72 |quote=Sorenson H.263 |year=2010 |access-date=January 27, 2011}}</ref> with mono MP3 audio.<ref>{{cite web|url=https://www.sorensonmedia.com/news/?n=379 |title=Market Demand for Sorenson Media's Sorenson Spark Video Decoder Expands Sharply |publisher=Sorenson Media |date=June 2, 2009 |access-date=July 31, 2009 |archive-url=https://web.archive.org/web/20090827160021/https://www.sorensonmedia.com/news/?n=379 |archive-date=August 27, 2009 |url-status=dead }}</ref> In June 2007, YouTube added an option to watch videos in [[3GP and 3G2|3GP]] format on mobile phones.<ref>{{cite web|url=https://www.downloadsquad.com/2007/06/17/youtube-mobile-goes-live/ |title=YouTube Mobile goes live |date=June 17, 2007 |access-date=August 11, 2010 |url-status=dead |archive-url=https://web.archive.org/web/20070620083032/https://www.downloadsquad.com/2007/06/17/youtube-mobile-goes-live/ |archive-date=June 20, 2007 }}</ref> In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels.<ref>{{cite web|title=YouTube Videos in High Quality |url=https://youtube.googleblog.com/2008/03/youtube-videos-in-high-quality.html |website=Official YouTube Blog |date=March 14, 2008 |access-date=March 25, 2017}}</ref> In December 2008, [[720p]] [[high-definition video|HD]] support was added.

YouTube videos are available in a range of quality levels. Viewers only indirectly influence the video quality.

===User features===

On September 13, 2016, YouTube launched a [[public beta]] of Community, a [[social media]]-based feature that allows users to post text, images (including [[GIF]]s), live videos and others in a separate "Community" tab on their channel.<ref>{{cite web|first=Sarah |last=Perez |title=YouTube gets its own social network with the launch of YouTube Community |url=https://techcrunch.com/2016/09/13/youtube-gets-its-own-social-network-with-the-launch-of-youtube-community/ |website=[[TechCrunch]] |publisher=[[AOL]] |date=September 13, 2016 |access-date=March 26, 2017}}</ref> Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these [[YouTuber]]s included [[Vlogbrothers]], [[AsapScience]], [[Lilly Singh]], [[MatPat|The Game Theorists]], [[Karmin]], [[The Key of Awesome]], The Kloons, [[Peter Hollens]], [[Rosianna Halse Rojas]], [[Sam Tsui]], [[Threadbanger]] and [[Vsauce#Vsauce3|Vsauce3]].<ref>{{cite web|first=Kiley |last=McEvoy |title=YouTube Community goes beyond video |url=https://youtube-creators.googleblog.com/2016/09/youtube-community-goes-beyond-video.html |website=YouTube Creators Blog |date=September 13, 2016 |access-date=March 25, 2017}}</ref>{{non-primary source needed|date=July 2021}}

Most videos enable users to leave comments, and these have attracted attention for the [[Troll (Internet)|negative]] aspects of both their form and content.

Google subsequently implemented a comment system oriented on Google+ on November 6, 2013, that required all YouTube users to use a Google+ account to comment on videos. The stated motivation for the change was giving creators more power to moderate and block comments, thereby addressing frequent criticisms of their quality and tone.<ref>[https://www.theguardian.com/technology/2013/nov/07/youtube-comments-trolls-moderation-google "YouTube aims to tame the trolls with changes to its comments section"], Stuart Dredge, ''The Guardian'', November 7, 2013.

Later, on July 27, 2015, Google announced in a blog post that it would be removing the requirement to sign up to a Google+ account to post comments to YouTube.<ref>{{cite news|date=July 28, 2015|title=Google unlinking Google+ from YouTube|work=BBC News|location=London|url=https://www.bbc.co.uk/news/technology-33687110|access-date=July 29, 2015}}</ref> Then on November 3, 2016, YouTube announced a trial scheme which allows the creators of videos to decide whether to approve, hide or report the comments posted on videos based on an [[algorithm]] that detects potentially offensive comments.<ref>{{cite web|last=E.

===Content accessibility===
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.<ref>{{Cite web|url=https://www.athenswalk.net/_/Blog/Entries/2013/7/30_YouTube_embed_code_guide.html|title=YouTube embedded video guide|access-date=February 17, 2022|archive-date=October 10, 2017|archive-url=https://web.archive.org/web/20171010095422/http://www.athenswalk.net/_/Blog/Entries/2013/7/30_YouTube_embed_code_guide.html|url-status=dead}}</ref> 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 can make a "video response". The eleven character YouTube video identifier (64 possible characters used in each position), allows for a theoretical maximum of 64<sup>11</sup> or around 73.8 quintillion (73.8 billion billion) unique ids.

YouTube announced that it would remove video responses for being an underused feature on August 27, 2013.<ref>{{cite web|title=So long, video responses ...

Since June 2007, YouTube's videos have been available for viewing on a range of [[Apple Inc.|Apple]] products. This required YouTube's content to be transcoded into Apple's preferred video standard, [[H.264/MPEG-4 AVC|H.264]], a process that took several months.

In December 2012, two billion views were removed from the view counts of Universal and [[Sony Music Entertainment|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.

Since September 2019, subscriber counts are abbreviated. Only three leading digits of channels' subscriber counts are indicated publicly, compromising the function of third-party real-time indicators such as that of [[Social Blade]].

On November 11, 2021, after testing out this change in March of the same year, YouTube announced it would start hiding dislike counts on videos, making them invisible to viewers.

YouTube has faced numerous challenges and criticisms in its attempts to deal with copyright, including the site's first viral video, [[Lazy Sunday (The Lonely Island song)|Lazy Sunday]], which had to be taken down, due to copyright concerns.<ref name=":8" /> At the time of uploading a video, YouTube users are shown a message asking them not to violate copyright laws.<ref>{{Cite news|last=Marsden|first=Rhodri|date=August 12, 2009|title=Why did my YouTube account get closed down?|work=The Independent|location=London|url=https://www.independent.co.uk/life-style/gadgets-and-tech/features/rhodri-marsden-why-did-my-youtube-account-get-closed-down-1770618.html |archive-url=https://ghostarchive.org/archive/20220507/https://www.independent.co.uk/life-style/gadgets-and-tech/features/rhodri-marsden-why-did-my-youtube-account-get-closed-down-1770618.html |archive-date=May 7, 2022 |url-access=subscription |url-status=live|access-date=August 12, 2009}}{{cbignore}}</ref> Despite this advice, many unauthorized clips of copyrighted material remain on YouTube.

YouTube contracts companies to hire content moderators, who view content flagged as potentially violating YouTube's content policies and determines if they should be removed. In September 2020, a class-action suit was filed by a former content moderator who reported developing [[post-traumatic stress disorder]] (PTSD) after an 18-month period on the job. The former content moderator said that she was regularly made to exceed YouTube's stated limit of four hours per day of viewing graphic content. The lawsuit alleges that YouTube's contractors gave little to no training or support for its moderators' mental health, made prospective employees sign NDAs before showing them any examples of content they would see while reviewing, and censored all mention of trauma from its internal forums. It also purports that requests for extremely graphic content to be blurred, reduced in size or made monochrome, per recommendations from the [[National Center for Missing and Exploited Children]], were rejected by YouTube as not a high priority for the company.<ref>{{cite web|last=Kimball|first=Whitney|date=September 22, 2020|title=Content Moderator Exposed to Child Assault and Animal Torture Sues YouTube|url=https://gizmodo.com/youtube-moderator-sues-over-ptsd-symptoms-lack-of-work-1845143110|access-date=October 11, 2020|work=Gizmodo}}</ref><ref>{{cite news|last=Vincent|first=James|date=September 22, 2020|title=Former YouTube content moderator sues the company after developing symptoms of PTSD|url=https://www.theverge.com/2020/9/22/21450477/youtube-content-moderator-sues-lawsuit-ptsd-graphic-content-exposure|access-date=October 11, 2020|work=The Verge}}</ref><ref>{{cite web|last=Elias|first=Jennifer|date=September 22, 2020|title=Former YouTube content moderator describes horrors of the job in new lawsuit|url=https://www.cnbc.com/2020/09/22/former-youtube-content-moderator-describes-horrors-of-the-job-in-lawsuit.html|access-date=October 11, 2020|publisher=CNBC}}</ref>

YouTube identified specific examples of such videos as those that "promote or glorify Nazi ideology, which is inherently discriminatory".

Following the dissemination via YouTube of [[misinformation related to the COVID-19 pandemic]] that [[5G]] communications technology was responsible for the spread of [[coronavirus disease 2019]] which led to multiple 5G towers in the United Kingdom being attacked by arsonists, YouTube removed all such videos linking 5G and the coronavirus in this manner.<ref name="guardian-youtube-to-suppress-content-spreading-coronavirus-5g-conspiracy-theory">{{Cite news|last=Hern|first=Alex|date=April 5, 2020|title=YouTube moves to limit spread of false coronavirus 5G theory|newspaper=[[The Guardian]]|url=https://www.theguardian.com/world/2020/apr/05/youtube-to-suppress-content-spreading-coronavirus-5g-conspiracy-theory|access-date=April 5, 2020}}</ref>

Google and YouTube implemented policies in October 2021 to deny monetization or revenue to advertisers or content creators that promoted [[climate change denial]], which "includes content referring to climate change as a hoax or a scam, claims denying that long-term trends show the global climate is warming, and claims denying that greenhouse gas emissions or human activity contribute to climate change."<ref>{{cite web|last=Peters|first=Jay|date=October 7, 2021|title=Google and YouTube will cut off ad money for climate change deniers|url=https://www.theverge.com/2021/10/7/22715102/google-youtube-climate-change-deniers-ads-monetization|work=[[The Verge]]|accessdate=October 7, 2021}}</ref>

Leading into 2017, there was a significant increase in the number of videos related to children, coupled between the popularity of parents vlogging their family's activities, and previous content creators moving away from content that often was criticized or demonetized into family-friendly material.

As a result of the controversy, which added to the concern about "Elsagate", several major advertisers whose ads had been running against such videos froze spending on YouTube.<ref name="forbes" /><ref>Todd Spangler, [https://variety.com/2017/digital/news/youtube-ad-boycott-pedophile-sexual-children-videos-1202622790/ YouTube Faces Advertiser Boycott Over Videos With Kids That Attracted Sexual Predators], ''[[Variety (magazine)|Variety]]'', November 25, 2017</ref> In December 2018, ''[[The Times]]'' found more than 100 grooming cases in which children were manipulated into sexually implicit behavior (such as taking off clothes, adopting overtly sexual poses and touching other children inappropriately) by strangers.<ref name=":5">{{Cite news|last=Bridge|first=Harry Shukman, Mark|date=December 10, 2018|title=Paedophiles grooming children live on YouTube|language=en|work=The Times|url=https://www.thetimes.co.uk/article/paedophiles-grooming-children-live-on-youtube-3fv8gt730|access-date=February 18, 2019|issn=0140-0460}}</ref> After a reporter flagged the videos in question, half of them were removed, and the rest were removed after ''The Times'' contacted YouTube's PR department.<ref name=":5" />

In February 2019, YouTube vlogger Matt Watson identified a "wormhole" that would cause the YouTube recommendation algorithm to draw users into this type of video content, and make all of that user's recommended content feature only these types of videos. Most of these videos had comments from sexual predators commenting with timestamps of when the children were shown in compromising positions or otherwise making indecent remarks. In some cases, other users had re-uploaded the video in unlisted form but with incoming links from other videos, and then monetized these, propagating this network.<ref name="bloomberg mwatson">{{cite news|last1=Bergen|first1=Mark|last2=de Vynck|first2=Gerrit|last3=Palmeri|first3=Christopher|date=February 20, 2019|title=Nestle, Disney Pull YouTube Ads, Joining Furor Over Child Videos|url=https://www.bloomberg.com/news/articles/2019-02-20/disney-pulls-youtube-ads-amid-concerns-over-child-video-voyeurs|access-date=February 20, 2019|work=[[Bloomberg News]]}}</ref> In the wake of the controversy, the service reported that they had deleted over 400 channels and tens of millions of comments, and reported the offending users to law enforcement and the [[National Center for Missing and Exploited Children]].

Subsequently, YouTube began to demonetize and block advertising on the types of videos that have drawn these predatory comments. The service explained that this was a temporary measure while they explore other methods to eliminate the problem.<ref>{{cite web|last=Ingraham|first=Nathan|date=February 22, 2019|title=YouTube is proactively blocking ads on videos prone to predatory comments|url=https://www.engadget.com/2019/02/22/youtube-blocking-ads-on-videos-predatory-comments/|access-date=February 22, 2019|work=[[Engadget]]}}</ref> YouTube also began to flag channels that predominantly feature children, and preemptively disable their comments sections. "Trusted partners" can request that comments be re-enabled, but the channel will then become responsible for moderating comments. These actions mainly target videos of toddlers, but videos of older children and teenagers may be protected as well if they contain actions that can be interpreted as sexual, such as gymnastics. YouTube stated it was also working on a better system to remove comments on other channels that matched the style of child predators.<ref>{{Cite news|last=Fox|first=Chris|date=February 28, 2019|title=YouTube bans comments on all videos of kids|language=en-GB|url=https://www.bbc.com/news/technology-47408969|access-date=March 2, 2019}}</ref><ref>{{cite web|last=Alexander|first=Julia|date=February 28, 2019|title=YouTube is disabling comments on almost all videos featuring children|url=https://www.theverge.com/2019/2/28/18244954/youtube-comments-minor-children-exploitation-monetization-creators|access-date=February 28, 2019|work=[[The Verge]]}}</ref>

A related attempt to algorithmically flag videos containing references to the string "CP" (an abbreviation of [[child pornography]]) resulted in some prominent false positives involving unrelated topics using the same abbreviation, including videos related to the mobile video game ''[[Pokémon Go]]'' (which uses "CP" as an abbreviation of the statistic "Combat Power"), and ''[[Club Penguin]]''.

YouTube stated they do not take action on any video with these comments but those that they have flagged that are likely to draw child predator activity.<ref>{{cite web|last=Alexander|first=Julia|date=February 28, 2019|title=Trolls are lying about child porn to try to get YouTube channels taken down|url=https://www.theverge.com/2019/2/28/18241925/youtube-creator-comments-weaponized-trolling-child-exploitation-lies-controversy-lies|access-date=February 28, 2019|work=[[The Verge]]}}</ref>

=== YouTube Stories ===
In 2018, YouTube started testing a new feature initially called "YouTube Reels".<ref>{{cite web|url=https://econsultancy.com/what-is-youtube-stories-will-it-catch-on/|title=What is YouTube Stories and will it catch on?|website=EConsultancy|last1=Gilliland|first1=Nikki|date=December 5, 2018|access-date=October 14, 2020}}</ref> The feature is nearly identical to [[Instagram Stories]] and [[Snapchat|Snapchat Stories]]. YouTube later renamed the feature "YouTube Stories".
