YouTube is a video hosting service created by former PayPal employees Chad Hurley, Steve Chen, and Jawed Karim in 2005. It was acquired by Google in November 2006 for US$1.65 billion and continues to operate as one of Google's subsidiaries. The site allows users to upload, view, rate, share, add to favorites, report, and comment on videos, and it makes use of WebM, H.265/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated and media videos. Available content includes but is not limited to video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, video blogs (vlogs), short original videos, and educational videos.

Most content on YouTube has been uploaded by individuals, but media corporations such as CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program. Unregistered users can watch videos on the site, but are encouraged to register in order to upload and add comments to videos. Videos deemed potentially offensive are available only to registered users who are at least 18 years old.

YouTube earns 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 Red, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users. As of February 2017, there are more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content is watched on YouTube every day. As of April 2017, the website is ranked as the second most popular site in the world by Alexa Internet, a web traffic analysis company.
