Facebook

As part of Mattel's grand marketing campaign for the Monster high franchise, the company has opened up a Monster High Facebook account. It receives an update a day, mainly in the form of small stories about the lives of the Monster High students. Other content that gets publicized there are fan spotlights, news on the webisodes' schedule, news on the books' releases, and notifications on the debutes of new characters. In late 2011, the Facebook account even hosted three contests to assign profiles to the three Create-a-Monster accessory pack monsters.

Aside from creating another source of entertainment for Monster High enthusiasts, Mattel also uses the Facebook account as feedback medium. In particular 'complaints' about the character of Operetta were addressed through and thanks to Facebook. When Operetta was introduced, she didn't have a mask, which was complained about by a few people. When she showed up again, she wore a mask. Similarly, remarks about Operetta's nationality, which some felt had to be French and not American, resulted in the release of part of her Monster High student file, explaining that her parents emigrated to the USA when she was young.

On December 16, 2011, Europeans and possibly fans from other continents were cut off from the Monster High Facebook account. While they still can read all the entries up to December 15, no younger updates are visible. Why this is, is currently unknown.
