Playlist

A YouTube playlist is a list of videos that are compiled by users in order to be played in the sequential order by which they are added. The videos usually come from other YouTube users and are usually compiled for any theme that the creating user may desire.

Playlists were first introduced to YouTube in 2008 after YouTube's groups were removed from in-site search indexing. Groups were previously used as a means to collaboratively add relevant videos to a common group pool of videos. However, playlists continue to lack the collaborative adding of videos.
