May 21 has been adopted by the United Nations as the World Day for Cultural Diversity for Dialogue and Development. On this occasion, Vivendi organizes this Thursday at 5 pm (Paris time) a special program (in French) on Vivoice, its CSR web radio. Irena Guidikova (Council of Europe), Frédéric Mion (Sciences Po), Pascal Nègre (Universal Music) and Jacques du Puy (Canal+ Overseas) will join the debate.  The program can be listened to on vivoice.vivendi.com and will be live tweeted on @WebradioVivoice (#Vivoice).
