A channel is a list of videos that are related by subject or theme. Channels are set up by your organization's CorporateTube administrator. For example, your administrator may name them according to different departments of your company, or by intended use.
Each channel can have multiple sub-channels. This makes it easier to file your videos. Sub-channels can be viewed by clicking the name of the main channel in the navigation bar, and then selecting an option from the resulting dropdown menu.
