This is a screenshot of Missouri State's YouTube Channel. User channels are viewable at https://www.youtube.com/[user's name], in this case https://www.youtube.com/missouristate. Note the level of customization and official appearance to this channel.
YouTube channels are merely the content and public profile attached to your user account. The video in the center is a spotlighted video, and below that are all uploaded videos, videos marked as favorites, and playlists.
To the right of the spotlighted video is a public profile with some information about the user or account. In the case of a University unit, this can help convey some information to direct interested users to more resources, such as your website or another social media presence.
