YouTube

In preparing the big game media franchise that Monster High was to be, Mattel set up a Monster High YouTube account on September 25, 2007. It was put to use on May 5, 2010, the day the franchise launched.

On May 5, 2010, the first four webisodes were uploaded, introducing the main function of the YouTube account: an accessible location for people to watch and rewatch Monster High webisodes. Generally, new webisodes are uploaded on Thursdays, while it takes until Friday for a new webisode to appear on the main website. The YouTube account also holds several uploads of Volume 1 teasers, the only volume to get those.

TV specials are not uploaded on the YouTube channel. The one exception is "New Ghoul @ School", which was uploaded on April 4, 2011, almost a year after the DVD was sold with four of the Dawn of the Dance dolls.

Occasionally, uploads related to other forms of marketing than the webisodes are made. On August 4, 2010, the Higher Deaducation advertisement was uploaded. Four days later followed the Fright Song music video and its 'Behind the Scenes'-documentary.

A special mention goes to the Ghoul Spirit advertisements. The first trailer for the game was uploaded on July 20, 2011. Several months later, between October 21 and November 21, came the rest. These latter trailers each highlighted a different chapter of the game, and at the end showed a code that could be used in the game to unlock locker decoration sets, different music during the ending, and extra diary entries.

On May 17, 2011, Mattel uploaded a short about the Kind Campaign, with whom Monster High had partnered up. A similar thing happened on May 13, 2012, which saw a short about WeStopHate uploaded to celebrate the partnership.

The Monster High YouTube account also hosts a few uploads made by fans.
