YouTube is a website that allows registered users to share an unlimited number of videos on the internet. YouTube was the brainchild of three former Pay-Pal employees, quickly emerged as a cultural phenomenon, and was purchased by Google for 1.65 billion dollars in 2006 . Non-registered members may view any public video uploaded to the site, while registered members may upload their own videos and make them available to the public. Because anyone may upload any non-copyrighted, non-obscene video to YouTube, the emergence of the site has encouraged a mass popularization of amateur filmmaking. Many of the most popular videos range from video blogs to sports videos to machinima. Despite YouTube's explicit policy forbidding copyrighted work, television series, film clips, and music videos often appear on the site.
Depending on the preferences of the uploader, registered users may rate and comment on most videos. In this way, YouTube has certain similar functions to blogs and is fully encapsulated in the idea of the Web 2.0.
