Channels are set up by your organization's CorporateTube administrator. A channel is a list of videos that are related by subject or theme. 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, which makes it easy to file 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. 

After selecting a channel, you can sort the list of videos by plays, rating, upload date or alphabetically by title.

If you hover with your mouse over a thumbnail of a video in a video list, you can already see a small preview of the video.
