ChatGPT Wikipedia

YouTube is an American social media and online video sharing platform owned by Google. In October 2023, the council of Porto Alegre, Brazil, unanimously approved a local ordinance proposed by councilman Ramiro Rosário that would exempt residents from needing to pay for the replacement of stolen water consumption meters; the bill went into effect on November 23. According to a 2024 study in the International Journal of Surgery, concerns include "research fraud, lack of originality, ethics, copyright, legal difficulties, hallucination". Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data.

These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. ChatGPT can find more up-to-date information by searching the web, but this doesn't ensure that responses are accurate, as it may access unreliable or misleading websites. The user can interrupt tasks or provide additional instructions as needed.

• Between November 2005 and April 2006, the company raised money from various investors, with Sequoia Capital and Artis Capital Management being the largest two.
• In March 2023, a bug allowed some users to see the titles of other users’ conversations.
• In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk.
• Despite its growth and success, the platform has been criticized for its facilitation of the spread of misinformation and copyrighted content, routinely violating its users’ privacy, excessive censorship, endangering the safety of children and their well-being, and for its inconsistent implementation of platform guidelines.
• To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers earning around $1.32 to $2 per hour to label such content.

For Creators

In March 2017, the government of the United Kingdom pulled its advertising campaigns from YouTube, after reports that its ads had appeared on videos containing extremist content. The platform was first tested in India and later expanded to other countries, including the United States in March 2021, with videos now able to be up to 1 minute long. In September 2020, YouTube announced that it would be launching a beta version of a new platform of 15-second videos, similar to TikTok, called YouTube Shorts. It also allowed users to preview videos, share downloaded videos through Bluetooth, and offered more options for mobile data control and video resolution.
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. It features a simplified user interface, curated selections of channels featuring age-appropriate content, and parental control features. YouTube also released YouTube Music, a third app oriented towards streaming and discovering the music content hosted on the YouTube platform. 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.
A total of 34 streaming services (including Paramount+, Showtime, Starz, MGM+, AMC+ and ViX+) were initially available for purchase. YouTube Movies & TV is a video on demand (VOD) service that offers movies and television shows for purchase or rental, depending on availability, along with a selection of movies (encompassing between 100 and 500 titles overall) that are free to stream, with interspersed ad breaks. As of September 2019, the app is available in 69 countries, including Hong Kong and Macau, and one province. YouTube Kids is an American children's video app developed by YouTube, a subsidiary of Google. It offers biggerz casino bonus advertising-free streaming, access to original programming, and background and offline video playback on mobile devices.
YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a DMCA takedown notice pursuant to the terms of the Online Copyright Infringement Liability Limitation Act. YouTube has faced numerous challenges and criticisms in its attempts to deal with copyright, including the site's first viral video, Lazy Sunday, which had to be taken down, due to copyright concerns. 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. 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. The platform aims to penalize creators using misleading or sensationalized titles, with potential actions including video removal or channel suspension.

new features to help creators shine on TV screens

In 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels. YouTube officially launched the "polymer" redesign of its user interfaces based on Material Design language as its default, as well as a redesigned logo that is built around the service's play button emblem in August 2017. The site grew rapidly; 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. In January 2024, YouTube had more than 2.7 billion monthly active users, who collectively watched more than one billion hours of videos every day.

• In the 2011 case of Smith v. Summit Entertainment LLC, professional singer Matt Smith sued Summit Entertainment for the wrongful use of copyright takedown notices on YouTube.
• 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”.
• As of 2025, ChatGPT’s website is among the top 5 most-visited websites globally, and has over 800 million active weekly users.
• That year, the company again changed its interface and at the same time, introduced a new logo with a darker shade of red.
• YouTube Premium was originally announced on November 12, 2014, as “Music Key”, a subscription music streaming service, and was intended to integrate with and replace the existing Google Play Music “All Access” service.

April Fools gags

In December 2024, YouTube began testing a new multiplayer feature for that service, supporting multiplayer functionality across desktop and mobile devices. 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. In late October 2023, YouTube began cracking down on the use of ad blockers on the platform. On February 16, 2023, Wojcicki announced that she would step down as CEO, with Neal Mohan named as her successor. In 2020, Roku removed the YouTube TV app from its streaming store after the two companies were unable to reach an agreement. 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.
One such workaround, popularized on Reddit in early 2023, involved making ChatGPT assume the persona of "DAN" (an acronym for "Do Anything Now"), instructing the chatbot that DAN answers queries that would otherwise be rejected by the content policy. ChatGPT is programmed to reject prompts that may violate its content policy. But, because the approximation is presented in the form of grammatical text, which ChatGPT excels at creating, it's usually acceptable. It retains much of the information on the Web, in the same way, that a JPEG retains much of the information of a higher-resolution image, but, if you're looking for an exact sequence of bits, you won't find it; all you will ever get is an approximation. The term "hallucination" as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation or bullshitting.
In May 2018, after London Metropolitan Police claimed that drill music videos glamorizing violence gave rise to gang violence, YouTube deleted 30 videos. Journalist Virginia Heffernan stated in The New York Times that such videos have "surprising implications" for the dissemination of culture and even the future of classical music. In cases where the entire site is banned due to one particular video, YouTube will often agree to remove or limit access to that video in order to restore service. YouTube, a video sharing platform, has faced various criticisms over the years, particularly regarding content moderation, offensive content, and monetization. YouTube VR allows for access to all YouTube-hosted videos, but particularly supports headset access for 360° and 180°-degree video (both in 2D and stereoscopic 3D).

Regional responses

To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers earning around $1.32 to $2 per hour to label such content. In the case of supervised learning, the trainers acted as both the user and the AI assistant. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.

In early 2018, Cohen began hinting at the possible launch of YouTube's new subscription music streaming service, a platform that would compete with other services such as Spotify and Apple Music. YouTube Premium was originally announced on November 12, 2014, as "Music Key", a subscription music streaming service, and was intended to integrate with and replace the existing Google Play Music "All Access" service. In 2013, YouTube teamed up with satirical newspaper company The Onion to claim in an uploaded video that the video-sharing website was launched as a contest which had finally come to an end, and would shut down for ten years before being re-launched in 2023, featuring only the winning video.
