Corinne Delattre, director of communication at Cartier International, said: "For the past two years, Cartier has embarked on a number of groundbreaking initiatives that unite luxury with new technology.
"Today, the world is connected by a network. Blogs, group or individual websites are no longer the signs of a new era, but are an established reality for a whole new generation. As a large brand we must be able to communicate to this new generation of adepts of the digital world -- the MySpace community makes that possible."
Cartier also features several charities on its MySpace community, including Action Against Hunger, and promotes their cause.
Travis Katz, managing director of international for MySpace, said: "Cartier's international campaign is a great representation of how an international brand can create relevant and local experiences seamlessly with the power of MySpace."
