Joost goes live with advertisers

Joost, the online video site developed by the makers of Skype and Kazaa, went live last week with 31 advertisers and programming from Viacom, CBS and others. Joost has been in beta for months, which meant existing users could invite a limited number of people to join. Now that the site is out of beta, existing users have unlimited invites. Joost claims to have 100 employees across Europe and the U.S., and says it's working with 20 media and brand advertising companies to develop marketing campaigns for its clients. Some of its advertisers include IBM, GM, L'Oreal, Warner Bros., Nokia and Vodafone.
