Founding and initial growth (2005–2006) YouTube was founded by Chad Hurley, Jawed Karim, and Steve Chen. The three were early employees at
PayPal and had become wealthy after
eBay's acquisition of the company. 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". Karim said the inspiration for YouTube 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 tsunami online, which led to the idea of a video-sharing site. Hurley and Chen said that the original idea for YouTube was a video version of an
online dating service and had been influenced by the website
Hot or Not. They created posts on
Craigslist asking attractive women to upload videos of themselves to YouTube in exchange for a $100 reward. Difficulty in finding enough dating videos led to a change of plans, with the site's founders deciding to allow all types of videos. YouTube began as a
venture capital–funded technology
startup. Between November 2005 and April 2006, the company raised money from various investors, with
Sequoia Capital and Artis Capital Management being the largest two. YouTube's early headquarters were situated above a pizzeria and a Japanese restaurant in
San Mateo, California. In February 2005, the company registered www.youtube.com. The first video was uploaded on April 23, 2005. Titled "
Me at the zoo", it shows co-founder Jawed Karim at the
San Diego Zoo and can still be viewed on the site. The same day, the company launched a public
beta and by November, a
Nike ad featuring
Ronaldinho became the first video to reach one million total views. The site exited beta in December 2005, by which time the site was receiving 8 million views a day. Clips at the time were limited to 100 megabytes, as little as 30 seconds of footage. YouTube was not the first video-sharing site on the Internet;
Vimeo was founded in November 2004, though that site remained a side project of its developers from
CollegeHumor. On December 17, 2005, the same week YouTube exited beta, NBCUniversal
Saturday Night Live ran a sketch "
Lazy Sunday" by
The Lonely Island. Besides helping to bolster ratings and long-term viewership for
Saturday Night Live, "Lazy Sunday"'s status as an early
viral video helped establish YouTube as an important website. The deal was finalized on November 13, 2006. Google's acquisition launched newfound interest in video-sharing sites;
IAC, which now owned
Vimeo, focused on supporting the content creators to distinguish itself from YouTube. By 2010, the company had reached a
market share of around 43% and more than 14 billion views of videos, according to
comScore. That year, the company simplified its interface to increase the time users would spend on the site. In 2011, more than three billion videos were being watched each day with 48 hours of new videos uploaded every minute. Most of these views came from a relatively small number of videos; according to a software engineer at that time, 30% of videos accounted for 99% of views on the site. That year, the company again changed its interface and at the same time, introduced a new logo with a darker shade of red. A subsequent interface change, designed to unify the experience across desktop, TV, and mobile, was rolled out in 2013. By that point, more than 100 hours were being uploaded every minute, increasing to 300 hours by November 2014. , April 2017 During that time, the company also went through some organizational changes. In October 2006, YouTube moved to a new office in
San Bruno, California. Hurley announced that he would be stepping down as chief executive officer of YouTube to take an advisory role and that
Salar Kamangar would take over as head of the company in October 2010. In April 2009, YouTube partnered with
Vevo. In April 2010,
Lady Gaga's "
Bad Romance" became the
most-viewed video, becoming the first video to reach 200million views on May 9, 2010. YouTube
faced a major lawsuit by
Viacom International in 2011 that nearly resulted in the discontinuation of the website. The lawsuit was filed due to alleged
copyright infringement of Viacom's material by YouTube. However, the
United States Court of Appeals for the Second Circuit ruled that YouTube was not liable, and thus, YouTube won the case in 2012.
Susan Wojcicki's leadership (2014–2023) Susan Wojcicki was appointed
CEO of YouTube in February 2014. In January 2016, YouTube expanded its headquarters in
San Bruno by purchasing an office park for $215 million. The complex has 51,468 square metres (554,000 square feet) of space and can house up to 2,800 employees. In August 2017, YouTube made its "Polymer"
Material Design interface the default and launched a new logo featuring the service's play button. Through this period, YouTube tried several new ways to generate revenue beyond advertisements. In 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels. This effort was discontinued in January 2018 and relaunched in June, with US$4.99 channel subscriptions. These channel subscriptions complemented the existing Super Chat ability, launched in 2017, which allows viewers to donate between $1 and $500 to have their comment highlighted. In 2014, YouTube announced a subscription service known as "Music Key", which bundled ad-free streaming of music content on YouTube with the existing
Google Play Music service. The service continued to evolve in 2015 when YouTube announced
YouTube Red, a new premium service that would offer ad-free access to all content on the platform (succeeding the Music Key service released the previous year), premium original series, and films produced by YouTube personalities, as well as background playback of content on mobile devices. YouTube also released
YouTube Music, a third app oriented towards streaming and discovering the music content hosted on the YouTube platform. The company also attempted to create products appealing to specific viewers. YouTube released a mobile app known as
YouTube Kids in 2015, which was designed to provide an experience optimized for children. It features a simplified user interface, curated selections of channels featuring age-appropriate content, and parental control features. Also in 2015, YouTube launched YouTube Gaming—a
video gaming-oriented vertical and app for videos and live streaming, intended to compete with the
Amazon.com-owned
Twitch. In April 2018,
a shooting occurred at YouTube's headquarters in San Bruno, California, which wounded four and resulted in the death of the shooter. By February 2017, one billion hours of YouTube videos were being watched every day, and 400 hours worth of videos were uploaded every minute. Two years later, the uploads had risen to more than 500 hours per minute. In response to EU officials requesting that such services reduce bandwidth to make sure medical entities had sufficient bandwidth to share information, YouTube and
Netflix said they would reduce streaming quality for at least thirty days as to cut bandwidth use of their services by 25% to comply with the EU's request. YouTube later announced that they would continue with this move worldwide: "We continue to work closely with governments and network operators around the globe to do our part to minimize stress on the system during this unprecedented situation." After a 2018 complaint alleging violations of the
Children's Online Privacy Protection Act (COPPA), the company was fined $170 million by the FTC for collecting personal information from minors under the age of 13. YouTube was also ordered to create systems to increase children's privacy. Following criticisms of its implementation of those systems, YouTube started treating all videos designated as "made for kids" as liable under COPPA on January 6, 2020. Joining the
YouTube Kids app, the company created a supervised mode, designed more for
tweens, in 2021. Additionally, to compete with
TikTok and
Instagram Reels, YouTube released
YouTube Shorts, a short-form video platform. During that period, YouTube entered disputes with other tech companies. For over a year, in 2018–19, no YouTube app was available for
Amazon Fire products. In 2020,
Roku removed the YouTube TV app from its streaming store after the two companies were unable to reach an agreement. 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
brigading. While some users praised the move as a way to discourage
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. YouTube co-founder
Jawed Karim referred to the update as "a stupid idea" and said that the real reason behind the change was "not a good one, and not one that will be publicly disclosed." He felt that users' ability on a social platform to identify harmful content was essential, saying, "The process works, and there's a name for it: the
wisdom of the crowds. The process breaks when the platform interferes with it. Then, the platform invariably declines." Shortly after the announcement, software developer Dmitry Selivanov created Return YouTube Dislike, an
open-source, third-party
browser extension for
Chrome and
Firefox that allows users to see a video's number of dislikes. In a letter published on January 25, 2022, by then YouTube CEO
Susan Wojcicki, acknowledged that removing public dislike counts was a controversial decision, but reiterated that she stands by this decision, claiming that "it reduced dislike attacks." In 2022, YouTube launched an experiment where the company would show users who watched longer videos on TVs a long chain of short unskippable adverts, intending to consolidate all ads into the beginning of a video. Following public outrage over the unprecedented amount of unskippable ads, YouTube "ended" the experiment on September 19 of the same year. In October, YouTube announced that they would be rolling out customizable user handles in addition to channel names, which would also become channel URLs.
Neal Mohan leadership (2023–present) On February 16, 2023, Wojcicki announced that she would step down as CEO, with
Neal Mohan named as her successor. Wojcicki took on an advisory role for Google and parent company
Alphabet. Wojcicki died a year and a half later from
non-small-cell lung cancer, on August 9, 2024. In late October 2023, YouTube began cracking down on the use of
ad blockers on the platform. Users of ad blockers may be given a pop-up warning saying "Video player will be blocked after 3 videos". Users of ad blockers are shown a message asking them to allow ads or inviting them to subscribe to the ad-free
YouTube Premium subscription plan. YouTube says that the use of ad blockers violates its terms of service. In April 2024, YouTube announced it would be "strengthening our enforcement on third-party apps that violate YouTube's Terms of Service, specifically ad-blocking apps". Starting in June 2024,
Google Chrome announced that it would be replacing Manifest V2 in favor of
Manifest V3, effectively killing support for most ad-blockers. Around the same time, YouTube started using server-side ad injection, which allows the platform to inject the ads directly into the video, instead of having the ad as a separate file which can be blocked. In September 2023, YouTube announced an in-app gaming platform called Playables. It was made accessible to all users in May 2024, expanding from an initial offering limited to premium subscribers. In December 2024, YouTube began testing a new multiplayer feature for that service, supporting multiplayer functionality across desktop and mobile devices. the Playables catalog has over 130 games in various genres, including
trivia, action, and sports. In December 2024, YouTube introduced new guidelines prohibiting videos with clickbait titles to enhance content quality and combat misinformation. The platform aims to penalize creators using misleading or sensationalized titles, with potential actions including video removal or channel suspension. According to YouTube, this guideline will gradually roll out in India first, but will expand to more countries in the coming months. On February 14, 2025, YouTube celebrated 20 years since its founding. On July 30, 2025, amid the implementation of the
Online Safety Act 2023 in the
United Kingdom, Google announced that it would begin to enforce "
age assurance" policies for selected users in the United States as a trial.
Machine learning will be used to determine the age of the user (regardless of any account information indicating their age) and restrict access to certain content and features across all Google properties, including YouTube (including, in particular, disabling personalized advertising and enabling certain digital wellbeing limits), if they are assumed to be under 18. On YouTube, this will be based on factors such as searches and video history, and the age of the account. The user must go through age verification via payment, scanned ID, or selfie to access all features if they are detected to be a minor. On April 9, 2025, YouTube expressed support for the NO FAKES Act of 2025, introduced by Senator
Chris Coons (D-DE) and Senator
Marsha Blackburn (R-TN), and announced an expansion of its pilot program that is designed to identify content generated by AI. On September 23, 2025, YouTube parent company Alphabet announced that it would reinstate creators who were banned for spreading
misinformation about COVID-19 and the
2020 U.S. presidential election. Within the context of the
suspension of Jimmy Kimmel and debates about
free speech in the United States, Vice President
JD Vance defended Kimmel's suspension and instead cited a letter sent by Alphabet legal counsel Daniel F. Donovan to
U.S. House Judiciary Committee chairman
Jim Jordan, claiming the
Biden administration pressured YouTube to remove "non-violative user-generated content" containing misinformation about the COVID-19 pandemic and the 2020 election, and announced that it would reinstate content creators previously banned due to the cited content; however, such claims have not formally been proven, and the
U.S. Supreme Court dismissed in 2024 the
First Amendment case
Murthy v. Missouri (which claimed the Biden administration had pressured social media companies to censor conservative views, government criticism, and COVID-19 misinformation), ruling 6–3 that neither the attorneys general of Missouri and Louisiana nor other respondents had standing to bring the case. The decision of Alphabet to bring back YouTube creators who engaged in
misinformation was criticized for prioritizing "free expression" over "facts". == Senior leadership ==
