[[파일:YouTube video player history.png|섬네일|유튜브 영상 플레이어의 대략적인 디자인 변천사. 각각의 레이아웃은 임베드 변수에 따라 달라질 수 있다는 점에 유의.]]
[[유튜브]]는 미국의 [[비디오 호스팅 서비스|온라인 영상 공유]] [[웹 플랫폼|플랫폼]]으로 [[캘리포니아주]] [[샌브루노]]에 본사를 두고 있다. 2005년 2월 [[페이팔]] 출신의 [[채드 헐리]], [[스티브 첸]], [[자베드 카림]]이 창업하였으며, 2006년 11월 [[구글]]이 16억 5000만 달러에 인수하였으며 현재까지 구글의 [[자회사]]로 남아 운영되고 있다.

유튜브는 유저들이 [[영상]]을 업로드해서 자유롭게 감상하는 서비스를 기반으로, [[좋아요 버튼|좋아요]]와 싫어요 버튼, 공유하기 기능, [[플레이리스트]] 추가 기능, 리포트 기능, 영상 댓글 기능, [[가장 많이 구독된 유튜브 채널 목록|구독 기능]]을 갖추고 있다. 유튜브의 기반이 되는 바탕으로 '내 손으로 방송하자' (Broadcast Yourself)라는 수년간의 슬로건은 물론, [[유저 프로필]]의 명칭을 '채널'로 설정함으로서, [[주문형 비디오|VOD]]의 영역을 대폭 확대시켜 누구나 [[텔레비전]] 방송처럼 개인 방송을 운영할 수 있도록 만들었다.

유튜브는 광범위한 [[UCC|유저 제작 영상]]과 기업 매체 영상을 제공하고 있다. 유튜브에서 볼 수 있는 콘텐츠로는 [[비디오 클립]], [[TV 프로그램]] 클립, [[뮤직 비디오]], [[단편 영화]], [[다큐멘터리 영화]], 음성 녹음본, 영화 [[예고편]], [[라이브 스트리밍]], [[브이로그]], 단편 오리지널 영상, [[에듀테인먼트|교육 영상]] 등이다.

2017년 2월 기준으로 유튜브에서 매 1분마다 업로드되는 동영상 콘텐츠의 양은 약 400시간 이상에 달하며, 하루 동안 유저들이 동영상을 보는 시간은 모두 합쳐서 10억 시간에 달한다. 2019년 5월 통계에서는 업로드되는 콘텐츠의 양이 1분당 약 500시간으로 집계되었다.<ref name="500hrs">{{뉴스 인용|author=Loke Hale, James|date=May 7, 2019|title=More Than 500 Hours Of Content Are Now Being Uploaded To YouTube Every Minute|work=[[TubeFilter]]|location=Los Angeles, CA|url=https://www.tubefilter.com/2019/05/07/number-hours-video-uploaded-to-youtube-per-minute/|access-date=June 10, 2019}}</ref> 또 2020년 10월 [[알렉사 인터넷]]에서 집계한 자료에 따르면, 유튜브는 [[구글]]의 뒤를 이어 전세계에서 두번째로 가장 많이 찾는 웹사이트에 올라 있다.<ref name="alexa">{{웹 인용|title=Youtube.com Traffic, Demographics and Competitors |url=https://www.alexa.com/siteinfo/youtube.com |website=www.alexa.com |access-date=2020-01-11 |language=en |archive-date=November 27, 2016 |archive-url=https://web.archive.org/web/20161127004253/http://www.alexa.com/siteinfo/youtube.com |url-status=dead }}</ref> 이와 함께 분기별 광고 수익 보고서에 따르면 유튜브가 벌어들이는 연간 수익은 150억 달러에 달하는 것으로 조사된다.

2005년 2월 14일 'YouTube.com'이란 도메인 주소가 열렸으며, 4월 23일에는 비디오 업로드 기능이 처음으로 활성화되었다. 당시 사이트 이름은 'Tune In, Hook Up'으로 세 사람이 스스로 생각한 아이디어였다. 초창기 사이트 컨셉은 [[온라인 데이팅 서비스]]였으며, 결과적으로 실패하였지만 비디오와 업로드 플랫폼은 예외로 남게 되었다.<ref>{{뉴스 인용|last=Dredge|first=Stuart|url=https://www.theguardian.com/technology/2016/mar/16/youtube-past-video-dating-website|title=YouTube was meant to be a video-dating website|date=2016-03-16|work=The Guardian|access-date=2020-04-18|language=en-GB|issn=0261-3077}}</ref>

=== 영상 공유 서비스로의 전환 ===
2004년 미국에서는 제38회 [[슈퍼볼]] 경기 하프타임 시간에 펼쳐진 [[저스틴 팀버레이크]]와 [[자넷 잭슨]]의 공연에서, 잭슨의 가슴 가리개를 뜯어내는 연출이 전국민이 보는 생방송에 노출되어버린 사고로 인한, 이른바 [[니플게이트]] 논란이 있었다. 하지만 정작 이 사건에 대한 영상을 인터넷 그 어디서도 찾을 수 없었던 세 사람은, 영상을 공유할 수 있는 온라인 플랫폼이 없다는 문제를 깨닫고, 최초의 대규모 비디오 공유 플랫폼이 되기 위한 웹사이트 개편에 나섰다.<ref>{{웹 인용|url=https://phrasee.co/the-history-of-youtube/|archive-url=https://web.archive.org/web/20200925140821/https://phrasee.co/the-history-of-youtube/|archive-date=2020-09-25|title=The history of YouTube|date=2016-05-09|website=Phrasee|language=en-GB|access-date=2021-02-14}}</ref> 이들이 생각한 새로운 창업 아이디어는 표준 웹 브라우저와 최신 인터넷 속도를 바탕으로, 컴퓨터를 잘 다루지 못하는 사람들에게 스트리밍 비디오를 배포하고, 업로드하고, 볼 수 있도록 해주는 간편한 인터페이스를 제공한다는 것이었다. 최종적으로 2000년대 초를 살아가는 새로운 인터넷 이용자들에게 스트레스를 안기지 않을 정도로 쓰기 쉬운 비디오 스트리밍 플랫폼을 제작한다는 계획이었다.<ref name=":2">Burgess, Jean, and Joshua Green.

이 시점에서 유튜브에 올라온 최초의 동영상으로 '[[Me at the zoo]]' (동물원에 간 나)라는 영상이 존재한다. 2005년 4월 23일에 업로드된 이 영상은 유튜브 공동설립자인 자베드 카림이 [[샌디에이고 동물원]]을 배경으로 시험 삼아 찍은 영상이며, 아직까지도 삭제되지 않고 남아서 1억 2000만 조회수와 좋아요 500만 개를 기록하고 있다.<ref name="Alleyne, Richard">{{뉴스 인용|url=https://www.telegraph.co.uk/news/uknews/2480280/YouTube-Overnight-success-has-sparked-a-backlash.html |archive-url=https://ghostarchive.org/archive/20220112/https://www.telegraph.co.uk/news/uknews/2480280/YouTube-Overnight-success-has-sparked-a-backlash.html |archive-date=January 12, 2022 |url-access=subscription |url-status=live|title=YouTube: Overnight success has sparked a backlash|date=July 31, 2008|work=[[The Daily Telegraph]] |location=London|author=Alleyne, Richard|access-date=January 17, 2009}}{{cbignore}}</ref><ref name="Jawed Karim and Yakov Lapitsky">{{웹 인용|url=http://www.youtube.com/watch?v=jNQXAC9IVRw |archive-url=https://ghostarchive.org/varchive/youtube/20211212/jNQXAC9IVRw| archive-date=2021-12-12 |url-status=live|title=Me at the Zoo|author=Jawed Karim and Yakov Lapitsky |format=Video|publisher=YouTube |date=April 23, 2005|access-date=August 3, 2009}}{{cbignore}}</ref>

사이트 개편 과정에서 헐리는 자신의 디자인 실력을 발휘해 유튜브의 로고를 만들고 레이아웃을 설계하는 등, 웹사이트의 외형을 고민하는 쪽을 맡았다.<ref name=":0">Owings, L. (2017). ''YouTube''.

=== 운영과 성장 ===
유튜브는 차고를 임시 사무실 삼아 시작하는, 일종의 [[엔젤 투자자|엔젤 투자]] 기업으로 첫발을 내딛었다. 2005년 11월 벤처기업 [[시쿼이아 캐피털]]에서 유튜브에 350만 달러를 우선 투자하고,<ref name="forbes">{{뉴스 인용|first=Scott|last=Woolley|url=http://members.forbes.com/global/2006/0313/027.html|title=Raw and Random|work=Forbes|date=March 3, 2006|access-date=July 28, 2006|archive-url=https://web.archive.org/web/20181122133536/http://members.forbes.com/global/2006/0313/027.html|archive-date=November 22, 2018|url-status=dead}}</ref>[[롤로프 보타]] 사 (시쿼이아의 파트너 기업이자 전 페이팔 CFO)도 유튜브 이사회에 합류하게 되었다. 2006년 4월, 시쿼이아와 아티스 캐피털 매니지먼트는 유튜브에 800만 달러를 추가로 투자하여, 유튜브는 서비스 개시 몇 달만에 엄청난 성장을 맛보게 되었다.<ref>{{뉴스 인용|url=http://thornbury.biz/sequoias-investment-memo-youtube/|title=Sequoia's Investment Memo on YouTube|date=June 11, 2016|work=Thornbury Bristol|language=en-GB|access-date=November 21, 2016|archive-url=https://web.archive.org/web/20161122005540/http://thornbury.biz/sequoias-investment-memo-youtube/|archive-date=November 22, 2016|url-status=dead|df=mdy-all}}</ref>

2005년 12월에는 대대적인 첫 기능 업데이트가 실시되었다. 댓글을 단 사람의 영상 업로드수, 좋아요수, 친구수가 댓글란에 직접 표시되도록 하였으며, 영상의 외부 링크, 추천 영상의 댓글수, 영상 리스트 검색 결과와 채널 페이지의 순위표를 새로 추가하였다. 이와 함께 "Broadcast yourself. Watch and Share your videos worldwide!" ({{해석|내 손으로 방송하자. 당신의 비디오를 전세계에 공유하고 감상하세요!}})라는 새로운 슬로건도 선보였는데, 이는 나중에 "Broadcast yourself"로 짤막하게 바뀌었다.<ref>{{웹 인용|url=http://www.youtube.com/watch.php?v=usRldgBlEBk&search=funny |title=YouTube - Baby Fart |website=[[YouTube]] |access-date=April 26, 2022 |archive-date=December 18, 2005 |archive-url=https://web.archive.org/web/20051218151541/http://www.youtube.com/watch.php?v=usRldgBlEBk&search=funny |url-status=bot: unknown }}</ref> 지금 시점에서는 이 당시 추가된 기능들이 대부분 제거된 상태이지만, 내 시청기록을 각 비디오가 링크로 걸린 플레이리스트로 표시되는 것은 여전히 남아있는 상태다.<ref>{{웹 인용|url=http://www.youtube.com/watch?v=0yD29fXQhSI&feature=PlayList&p=72677A5526D27B3C&index=52 |title=YouTube - Nintendo Show |website=[[YouTube]] |access-date=April 26, 2022 |archive-date=February 8, 2007 |archive-url=https://web.archive.org/web/20070208165919/http://www.youtube.com/watch?v=0yD29fXQhSI&feature=PlayList&p=72677A5526D27B3C&index=52 |url-status=bot: unknown }}</ref>

2005년 5월 베타서비스를 개시할 당시 유튜브는 한달에 약 3만 명의 트래픽을 기록하였으나, 출범 6개월을 맞이한 시점에서는 하루에 200만 명 이상이 방문하는 웹사이트로 발돋움하였다. 2006년 3월에는 유튜브에 올려진 영상 개수가 총 2500만 건을 넘었으며, 하루에 2만 개의 업로드가 이뤄지는 수준으로 성장하였다.<ref name=":1">{{웹 인용|url=https://www.britannica.com/topic/YouTube|title=YouTube {{!}} History, Founders, & Facts|website=Encyclopædia Britannica|language=en|access-date=2020-04-18}}</ref> 2006년 여름이 되면 유튜브는 하루 업로드수가 6만 5000건을 넘기며, 인터넷에서 가장 빠르게 성장하는 웹사이트로 꼽히게 되었다.<ref name="adage_fastest">[http://adage.com/digital/article.php?article_id=110632 "YouTube is the Fastest Growing Website"], Gavin O'malley, [[Advertising Age]], July 21, 2006.</ref> 6월에 미국의 방송사 [[NBC]]와 마케팅, 광고 파트너십을 체결하게 된 유튜브는<ref>{{뉴스 인용|title=Online Video: The Market Is Hot, but Business Models Are Fuzzy|url=http://knowledge.wharton.upenn.edu/article/online-video-the-market-is-hot-but-business|access-date=August 25, 2017}}</ref> 7월 들어 하루에 약 100만 건의 영상 시청이 이뤄지는 것으로 집계되는 거대 사이트가 되어 있었다.<ref name="usatoday100million">{{뉴스 인용|title=YouTube serves up 100 million videos a day online |url=https://usatoday30.usatoday.com/tech/news/2006-07-16-youtube-views_x.htm|work=USA Today|agency=Reuters|date=July 16, 2006|access-date= November 29, 2008}}</ref>

하지만 이런 성장 속에는 어려움도 있었다. 급격한 성장으로 불어난 유저수는 곧 유튜브가 그에 걸맞는 기술적인 소통을 통해 계속해서 유지해야 한다는 뜻이기도 했다. 유튜브 측은 서버 장비와 브로드밴드 인터넷 접속량을 계속해서 도입해 나가며 유입을 뒷받침했다. 점차 증가하는 저작권 위반 문제와 광고화 수단 부족 문제 역시, 유튜브로 하여금 훗날 [[구글 비디오|자체 비디오 서비스]]를 운영하다 실패를 맛본 [[구글]] 측에 위탁하는 원인으로 작용하게 되었다.<ref name=":1" />

2006년 한 해 유튜브는 [[알렉사 인터넷|알렉사]] 통계에서 5번째로 가장 많이 찾는 웹사이트로 조사되었으며, 성장률로 따지면 [[마이스페이스]]를 한참 능가하고 있었다.<ref>{{웹 인용|url=http://www.alexa.com/data/details/traffic_details?&range=max&size=large&compare_sites=myspace.com&y=r&url=youtube.com#top|title=Info for YouTube.com|access-date=July 26, 2006|date=July 26, 2006|work=Alexa.com|archive-date=November 3, 2007|archive-url=https://web.archive.org/web/20071103011300/http://www.alexa.com/data/details/traffic_details?&range=max&size=large&compare_sites=myspace.com&y=r&url=youtube.com#top|url-status=dead}}</ref> [[닐슨 레이팅|닐슨/넷레이팅]]의 조사에서는 매달 평균 약 2000만 명이 방문하는 것으로 집계되었으며,<ref name="usatoday100million"/> 유저 성비는 여자 44%, 남자 56%로 조사됐다. 연령대로는 12세~17세가 1위를 차지했다.<ref name="nielsen-net-ratings-july06">{{웹 인용|url=http://www.videodownloadx.com/pr_060721_2.pdf|title=YouTube U.S. Web Traffic Grows 17 Percent Week Over Week, According to Nielsen//Netratings|access-date=September 12, 2006|date=July 21, 2006|format=Press Release|work=Netratings, Inc.|publisher=Nielsen Media Research}}</ref> 온라인 시장에서 유튜브가 차지하는 비중도 상당하여, Hitwise.com의 조사에 따르면 유튜브는 영국 온라인 비디오 시장의 64%를 차지하는 것으로 나타났다.<ref name="YouTube Google Zeitgeist">{{뉴스 인용|url=http://www.eurekastreet.com.au/article.aspx?aeid=1837|title=Google pays the price to capture online video zeitgeist|work=Eureka Street|volume=16|number=15|author=James Massola|publisher=Jesuit Communications Australia|date=October 17, 2006|access-date=October 18, 2006|archive-url=https://web.archive.org/web/20180825073808/http://www.eurekastreet.com.au/article.aspx?aeid=1837|archive-date=August 25, 2018|url-status=dead}}</ref>

참여형 영상 광고는 지금처럼 플랫폼 전체에 한번 광고하는 것이 아니라, 특정 채널에서 특정 프로모션을 링크하도록 만들어진 것이었다. 이 같은 광고 방식을 도입한 뒤 2006년 8월 유튜브의 CEO [[채드 헐리]]는 "우리는 사람들이 콘텐츠를 감상하기 전에 광고를 보도록 강요하는 것보다 더 나은 방법으로 브랜드에 관여할 수 있다고 생각한다. 인터넷 상의 아무에게나 그런 경험에 만족하냐고 물어보라. 아마 그렇지 않다고 대답할 것이다"라는 말을 남겼다. 당시로선 광고 영역을 확대하여 모든 유저에게 광고를 노출하는 것이 유저 친화적이지 못하다고 여겼던 셈이다.<ref name="Morrissey" /> 하지만 유튜브는 2007년 8월부터 영상 내 일반 광고를 게시하기 시작하였고, 2008년부터는 재생 전 광고가 도입되어 지금의 모습으로 바뀌었다.<ref name="Jackson">{{웹 인용|last=Jackson|first=Nicholas|date=August 3, 2011|title=Infographic: The History of Video Advertising on YouTube|url=https://www.theatlantic.com/technology/archive/2011/08/infographic-the-history-of-video-advertising-on-youtube/242836/|access-date=February 28, 2021|magazine=[[The Atlantic]]}}</ref>

The other gags are covered in {{section link|YouTube#April_Fools_Gags}}.

In June 2008, {{Visible anchor|Annotations|text=video annotations}} were introduced. Users were able to add text boxes and speech bubbles at any desired location and custom sizes in various colours, and optionally with a link and short pausing, allowing for interactive videos. In February 2009, the feature was extended to allow for collaboration, meaning uploaders could invite others to edit their video's annotations.<ref>{{웹 인용|last1=DaveWeLike |title=Youtube Annotations |url=http://www.stuffwelike.com/2008/06/03/youtube-annotations/ |website=StuffWeLike |access-date=7 August 2021 |date=4 June 2008}}</ref><ref>{{웹 인용|title=New on YouTube: Collaborative Annotations |url=https://readwrite.com/2009/02/20/youtube_collaborative_annotations/ |website=ReadWrite |access-date=7 August 2021 |date=20 February 2009}}</ref><ref>{{웹 인용|last1=Eves |first1=Derral |title=How To Create YouTube Video Annotations |url=https://derraleves.com/how-to-create-youtube-video-annotations-2/ |website=DerralEves.com |access-date=7 August 2021 |date=6 February 2013}}</ref> On May 2, 2017, [[#Annotations_locked|annotations were locked from editing]], and on January 15, 2019, [[#Annotations_removal|they were entirely shut down]].

YouTube relaunched its design and layout in early December 2012 {{citation needed span|to resemble the mobile and tablet app version of the site.|date=September 2021}} Notable changes of the watch page are the relocation of title and the "Subscribe" button from above to below the video's viewport, the removal of the button that opened a section above the video viewport showing other videos of the same channel without needing to leave the watch page, and the removal of a button-sized [[Web banner|banner]] located above the viewport, which could contain a custom image, popularly icons and text logos.<ref>Before change: {{웹 인용|url=http://www.youtube.com/watch?v=9bZkp7q19f0 |title=PSY - GANGNAM STYLE (강남스타일) M/V - YouTube |website=[[YouTube]] |access-date=September 24, 2021 |archive-date=December 3, 2012 |archive-url=https://web.archive.org/web/20121203214046/http://www.youtube.com/watch?v=9bZkp7q19f0 |url-status=bot: unknown }}; after change:</ref> Playlists on the watch page, which were formerly displayed as collapsible horizontal list fixed at the page bottom, became a scrollable vertical list next to the video player.<ref>Before change: {{web archive |url=https://web.archive.org/web/20120911012824/http://www.youtube.com/watch?v=RQlrSvnG3dg&list=PL57A31A57F0DBD2B2 }}; after change: {{web archive |url=https://web.archive.org/web/20121207220641/http://www.youtube.com/watch?v=RQlrSvnG3dg&list=PL57A31A57F0DBD2B2 }}</ref>

On December 21, 2012, the "[[Gangnam Style]]" music video by South-Korean musician [[PSY]] became the first YouTube video to surpass one billion views.<ref>{{뉴스 인용|last1=Burns|first1=Matt|title=Gangnam Style Hits 1 Billion YouTube Views, The World Does Not End|url=https://techcrunch.com/2012/12/21/i-still-dont-know-what-he-is-saying/|access-date=21 November 2016|work=TechCrunch}}</ref>

In early 2013, YouTube introduced a new layout for channels known as "One Channel", which added the ability to put playlists into shelves on the channel front page, but removed custom backgrounds. Formerly unified channel pages were separated into multiple sub pages such as "Videos", "Playlists", "Discussion" (channel comments), "Channels" (featured by user), and "About" (channel description, total video view count, join date, outlinks). This layout was initially optional, with a transitional period taking place between March 8 and June 5 after which it has been made permanent for all users. Coarsely, this layout is still in operation as of 2022.<ref>{{웹 인용|title=Tips on How to Convert to the New YouTube Channel Design 2013 {{!}} Black Box Social Media |url=https://blackboxsocialmedia.com/youtube-channel-redesign-2013/ |date=March 2013}}</ref>

On September 12, 2013, the "video responses" feature introduced back in May 2006 was discontinued, citing a low [[click-through rate]]. It allowed users to respond to videos through a new or existing video which appeared above the comment section.<ref>{{웹 인용|title=Google Dumps Video Responses From YouTube Due To Dismal .0004% Click-Through Rate |url=https://techcrunch.com/2013/08/27/google-dumps-video-responses-from-youtube-due-to-dismal-0004-click-through-rate/ |website=TechCrunch |date=27 August 2013 |access-date=6 August 2021}}</ref>

In the same month, YouTube's comment system on channel pages, and two months later on videos, was integrated to Google's [[social network]] site "[[Google+]]", since which a Google Brand Account is required to be able to comment. This change also included the ability to edit existing comments and include [[URL]]s in comments, with the removal of the 500 characters limit and negative user ratings from comments. Channels created prior as standalone YouTube accounts using its legacy registration form have been [[Grandfather clause|grandfathered]] to a <code>/user/</code> URL.<ref>{{웹 인용|last1=Janakiram |first1=Nundu |last2=Zunger |first2=Yonatan |title=We hear you: Better commenting coming to YouTube |url=https://blog.youtube/news-and-events/youtube-new-comments/ |website=blog.youtube |publisher=YouTube company blog |access-date=20 September 2021 |language=en-us |date=2013-09-24}}</ref><ref>{{웹 인용|title=Understand your channel URLs - YouTube Help |url=https://support.google.com/youtube/answer/6180214?hl=en |website=support.google.com}}</ref>

In November 2013, YouTube's own YouTube channel surpassed Felix Kjellberg's [[PewDiePie]] channel to become the [[List of the most subscribed channels on YouTube|most subscribed channel]] on the website. This was due to auto-suggesting new users to subscribe to the channel upon registration.<ref>{{웹 인용|last=Cohen|first=Joshua|url=http://www.tubefilter.com/2013/11/04/youtube-most-susbcribed-channel/|title=YouTube Is Now The Most Subscribed Channel On YouTube|work=Tubefilter|date=November 4, 2013|access-date=November 29, 2013}}</ref>

Users of the mobile app can reply to comments since April 2014.<ref name=NDTV-2014-04 />

In June 2014, YouTube replaced the classic Inbox feature with a new private messaging system, which – like comments – required users to have their YouTube accounts linked with a Google+ profile, which was subsequently moved over to Google Brand Accounts. Legacy Inbox messages could be viewed and downloaded up until December 1.<ref>{{웹 인용|title=Goodbye YouTube InBox, Hello Google+ YouTube Messages |url=https://tubularinsights.com/youtube-messages/|website=tubularinsights.com|date=June 25, 2014|access-date=February 10, 2022}}</ref><ref>{{웹 인용|title=Making messages and comments easier to use |url=https://blog.youtube/news-and-events/making-messages-and-comments-easier-to/|website=blog.youtube |publisher=YouTube Official Blog |author=Jeffrey Lee-Chan |date=June 24, 2014|access-date=February 10, 2022}}</ref>

In October 2014, videos' frame rate limit was increased from 30 to 60, allowing for a smoother and more realistic appearance.

Another change reported in September 2019 was a strictening of the [[account verification]] procedure. Previously, the sole criterion for verification is said to have been a subscriber count of at least 100.000, whereas since, YouTube reports requiring what they describe as a "proof of authenticity", incorporating notability outside of YouTube.

The latter likely applies, as that date is indicated on the watch page after initial publication.}} were set to private, making them unplayable except on channels whose owners intervened by manually opting out.<ref>{{웹 인용|last1=Li |first1=Abner |title=YouTube will make Unlisted videos uploaded before 2017 private next month |url=https://9to5google.com/2021/06/23/youtube-unlisted-videos/ |website=9to5Google |access-date=5 August 2021 |date=23 June 2021}}</ref><ref>{{웹 인용|title=Older unlisted content - YouTube Help |url=https://support.google.com/youtube/answer/9230970?hl=en |website=support.google.com |access-date=5 August 2021}}</ref>

Around that time, a study conducted by web archivists has concluded that over half of the videos which were on air on the platform around 2010 were no longer available by 2021. Such videos were either reversibly set to "private" or irreversibly erased, the latter of which occurred for the majority of those videos. Videos are taken down as a result of individual policy or copyright violation, channel terminations, retroactive policy changes, and voluntarily by uploaders.<ref>{{웹 인용|title=YouTube was made for Reuploads |url=https://datahorde.org/youtube-was-made-for-reuploads/ |website=Data Horde |access-date=14 August 2022 |date=28 July 2021}}</ref>

On August 24, 2021, YouTube sent a [[cease and desist]] to the developers of Groovy, a [[Discord (software)|Discord]] [[Internet bot|bot]] which enabled audio from YouTube videos to be played in Discord voice chats, as the bot violated YouTube's Terms of Service.<ref name=":3">{{웹 인용|last=Warren|first=Tom|date=2021-08-24|title=YouTube is forcing the popular Groovy Discord music bot offline|url=https://www.theverge.com/2021/8/24/22640024/youtube-discord-groovy-music-bot-closure|access-date=2021-08-27|website=The Verge|language=en}}</ref><ref>{{웹 인용|title=Discord music bot Groovy is going offline after YouTube crackdown|url=https://www.engadget.com/groovy-bot-discord-youtube-music-145236619.html|access-date=2021-08-27|website=Engadget|language=en-US}}</ref><ref>{{잡지 인용|last=Clayton|first=Natalie|date=2021-08-25|title=Google has killed Discord's best music bot|url=https://www.pcgamer.com/google-has-killed-discords-best-music-bot/|access-date=2021-08-27|magazine=PC Gamer|language=en-US}}</ref> A YouTube spokesperson stated, "We notified Groovy about violations of our Terms of Service, including modifying the service and using it for commercial purposes."<ref name=":3" /> In a message announcing the bot's closure, the owner of Groovy, Nik Ammerlaan, said, "Groovy has been a huge part of my life over the past five years. It started because my friend's bot sucked and I thought I could make a better one."<ref name=":3" />

In September 2021, the dedicated "view attributions" page was discontinued citing low usage.<ref>{{웹 인용|title=Creative Commons - YouTube Help |url=https://support.google.com/youtube/answer/2797468 |website=support.google.com |access-date=29 September 2021 |quote=The view attributions page will be discontinued after September 2021 due to limited usage.}}</ref>

In October 2021, YouTube experimented with indicating the most watched parts of a video through a solid line chart appearing on the seek bar in the mobile app to facilitate watchers finding relevant parts.<ref>{{웹 인용|last1=Wilde |first1=Damien |title=YouTube UI test highlights 'Most viewed' video portions in playback progress bar graph |url=https://9to5google.com/2021/10/11/youtube-ui-test-highlights-most-viewed-video-portions-in-playback-progress-bar-graph/ |website=9to5Google |access-date=1 January 2022 |date=11 October 2021}}</ref>

All channels' "Discussion" sub page is to be ultimately discarded on October 12, 2021. The feature was known as "Channel comments" in the site's early age, and served as channels' general comment section. Previously, it was gradually replaced with the {{visible anchor|communitypage|text="Community" page}} that first rolled out to select channels, and since approximately 2018 to channels surpassing a subscriber count threshold that decreased over time, discarding existing discussions. During the same day, YouTube lowered the threshold to the Community page from 1000 to channels with at least 500 subscribers.<ref>{{웹 인용|title=How to Use the YouTube Community Tab to Engage Subscribers : Social Media Examiner |url=https://www.socialmediaexaminer.com/how-to-use-youtube-community-tab-to-engage-subscribers/ |website=Social Media Examiner {{!}} Social Media Marketing |access-date=27 September 2021 |date=2018-02-07 |quote=The Community tab is rolling out first to select YouTube channels (both verified and non-verified) with over 10,000 subscribers}}</ref><ref>{{웹 인용|title=Expanding Community Posts to Channels with 500+ Subscribers and Removing the Discussion Tab - YouTube Community |url=https://support.google.com/youtube/thread/125117248/expanding-community-posts-to-channels-with-500-subscribers-and-removing-the-discussion-tab?hl=en |website=support.google.com |publisher=Team YouTube |date=2021-09-10}}</ref> The "Discussion" page was closed down earlier on the mobile site.<ref>{{웹 인용|title= qwert - YouTube | website=[[YouTube]] |url= https://m.youtube.com/user/qwert/discussion?app=m |date= 2021-10-03 |archiveurl= https://archive.today/20211003012505/https://m.youtube.com/user/qwert/discussion?app=m |archivedate= October 3, 2021 |quote= The Discussion tab is no longer supported on Mobile Web.

On November 10, 2021, YouTube announced the removal of videos' count for negative user ratings (also known as "dislikes" and "thumbs down"), reportedly to protect creators from online harassment. The dislike count remains solely visible to respective channel owners. This change was first tested with select users in March and again in July.<ref>{{웹 인용|title=YouTube tests hiding dislike counts on videos |url=https://social.techcrunch.com/2021/03/30/youtube-tests-hiding-dislike-counts-on-videos/ |website=TechCrunch |access-date=13 November 2021 |date=2021-03-30}}</ref><ref>{{웹 인용|title=An update to dislikes on YouTube |url=https://blog.youtube/news-and-events/update-to-youtube/ |website=blog.youtube |access-date=12 November 2021 |language=en-us |date=10 November 2021 |quote=This is just one of many steps we are taking to continue to protect creators from harassment. }}</ref><ref>{{웹 인용|last1=Bhattacharya |first1=Ananya |title=YouTube is scrapping the dislike count for viewers—but the button is staying |url=https://qz.com/2088620/why-is-youtube-scrapping-the-dislike-count-on-videos/ |website=Quartz |access-date=12 November 2021 |language=en |date=12 November 2021}}</ref>-->

== 지역판 서비스 ==
2007년 6월 19일 구글의 [[에릭 슈미트]] CEO는 프랑스 파리에서 유튜브의 각 국가별 서비스, 즉 [[국제화와 지역화|지역별]] 페이지를 출범 개시한다고 밝혔다.<ref name="local" /> 이에 따라 유튜브의 인터페이스가 전세계 공통 서비스에 머무르던 것을 넘어서, 전세계 108개국과 [[홍콩|1지역]]에 해당되는 개별 서비스를 개시하게 되었다.

각 지역판 서비스 개시일자는 다음과 같다.

2009년 3월에는 유튜브와 영국 [[로열티|저작권]] 관리기관인 [[PRS 포 뮤직]]과의 마찰이 벌어지면서, 영국 내 유튜브 유저들을 대상으로 프리미엄 뮤직비디오 시청이 차단되는 일이 있었다. 양측의 라이센스 계약이 합의에 도달하지 못하면서 주요 음반사들이 게시한 영상을 삭제한 것인데, 2009년 9월 소강 상태에 이르면서 영상들도 원상 복구되었다.<ref>{{뉴스 인용|title= Music videos back on YouTube in multi-million pound PRS deal|author=Barnett, Emma |work=The Daily Telegraph |location= London  |url = https://www.telegraph.co.uk/technology/google/6127624/Music-videos-back-on-YouTube-in-multi-million-pound-PRS-deal.html |date= September 3, 2009 |access-date= September 3, 2009}}</ref> 2009년 4월에는 독일에서도 비슷한 저작권 계약 분쟁이 벌어지면서 프리미엄 뮤직비디오의 시청이 차단되는 일이 있었다.<ref>{{뉴스 인용|title= Now YouTube stops the music in Germany |work= The Guardian |location= London | url = https://www.theguardian.com/media/pda/2009/apr/01/youtube-digital-music-and-audio |date=April 1, 2009 |access-date= April 2, 2009}}</ref>
