Essentially Unlisted Videos are private videos that anyone can view if, and only if, they have access to the video URL. These videos will not show up on public pages, in search results or on user channels. There's no limit on the amount of people who can view the video, and anyone can see it, regardless of whether or not they have a YouTube account.
Unlisted Videos should be welcomed by users not satisfied with the existing public and private options. Heretofore private videos could only be shared with other YouTube users. This new option is perfect for teachers, students, non-profits, organizations and anyone else who wants to upload a video to YouTube, share it, but not expose it to the world.
We think it's a smart addition to the YouTube feature set and one we could imagine using ourselves. Will you use the Unlisted Videos option?
