Playlists are a great way to organize and share the stuff you find on YouTube. You can think of playlists as a mix-tape, but for videos instead of music! For example, you might want to collect some of your favorite science videos to watch again later. Once you've created a playlist, it's easy to share it with your friends. Watch this video from the YouTube Help channel to learn how to create and share playlists:
To create a playlist:
Locate and select the Add to button below the video player. A menu will appear. From here, you can choose to add the video to an existing playlist or create a new one. In our example, we'll choose Create new playlist.
Type the playlist name, choose the desired privacy level for the playlist, and choose Create.
The playlist will be created. You can now add videos to the playlist at any time. To view or manage the playlist, you can select it from the Guide. To share a playlist, click the Share button.
