YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate mediavideos. Available content includes video clips, TV show clips, music videos, shortand documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.

YouTube and selected creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google.^[2] As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.^[7]Based on reported quarterly advertising revenue, YouTube is estimated to have US$15 billion in annual revenues.

YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos,^[8] its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods,^[9]hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters,^[10] videos of minors attracting pedophilic activities in their comment sections,^[11] and fluctuating policies on the types of content that is eligible to be monetized with advertising.^[8]
