Vivendi, the French conglomerate whose corporate portfolio is even harder to parse than IAC's, is reentering the business of providing mobile content, six years after it exited the market. Last time around, Vivendi's venture was called Vizzavi; this time, it's called Zaoza, which means something in Chinese. What the congratulatory launch announcements don't tell you: Zaoza is months late, having been promised for last fall.
