SpaceRip: Making Tracks On Mars

Tags are keywords or category labels that can help you and others find videos on Hulu. They also classify videos for later recall. You can tag videos yourself by simply checking the box next to a popular tag for a video or by using the "add" field to create a new tag. Click on any tag — "comedy" for example — to discover other videos similarly tagged by you or other users. Because tags are reviewed by Hulu, there may be a delay in surfacing your tags. The most relevant tags are sorted by category for the rest of Hulu to see. You may assign up to 30 tags for any video or show; to review all of your tags, see the Tags section on your profile page.

Your tags may be visible to other users on Hulu. You should not use:

Profane or obscene language
Tags that are inciting or spiteful
Tags that might harass, abuse or threaten members of the community
Tags that may reveal your personal information or any personal information about children under age 13
Tags that promote illegal or immoral conduct
Tags containing special characters or more than 50 characters
