Paris - Vivendi has launched a subscription-based mobile content service, Zaoza, that charges users about $4.42 per month for unlimited downloads of music, ringtones, games and videos, MocoNews reported. Content partners at launch include Sony BMG, THQ and Eidos. The site already claims 100,000 beta users in France. Vivendi hopes to grow this number to 500,000 by year's end, spurred by launches in Germany and the U.K. planned for later this year.
