"Sesame Street" Executive Producer Carol-Lynn Parente said Monday that YouTube had taken the channel down Sunday after noticing the racy material. The channel usually carries new and vintage clips from the popular preschool program.
Parente says it appears that the X-rated videos were online for less than an hour and that "Sesame Street" had received no viewer complaints.
YouTube says it counsels clients to adopt tougher security to avoid hackers. The channel was expected to resume Monday afternoon..
