Disney is an important ally for YouTube, which walks a careful line when it comes to attracting children; the site's Terms of Service require users to be at least 13 years old to watch videos and register for an account, though younger children routinely access the site.

An article on Monday about an online video series being developed by Disney and YouTube referred incorrectly to YouTube’s position on the use of the site by children.

It is not the case that YouTube lacks a policy regulating access by children.
