Already on Facebook and Twitter, Prince Haakon and Mette-Marit join another social-networking site

Haakon and Mette-Marit launch official Norwegian royal YouTube channel

Many of Europe's royal families are reaching out through social networking sites, and Norway's Crown Prince Haakon and Crown Princess Mette-Marit are no exception.

The royal couple already have Facebook and Twitter pages and now they have announced their own YouTube channel, following in the footsteps of Queen Rania of Jordan and the British Monarchy.

The page features a mix of new videos and older clips previously posted on the monarchy's web site, such as a recent one of the children decorating a giant gingerbread house at Christmas. The family say that they plan to use YouTube to show people their current activities as well as their history.

In many of the videos, Haakon and Mette-Marit share news about the causes and organisations they work with.

One recently made clip supports Redesign Our World, an initiative to involve young people in the work of the World Economic Forum, which the Crown Prince is currently attending in Davos.

In the video, the couple appear alongside their three children, Princess Ingrid Alexandra, Prince Sverre Magnus and Marius. Together, they are all smiles as they hold up signs that read "We believe in young people. Involve them."
