Facebook is teaming up with Beijing-based real-time-bidding specialist iPinYou in an attempt to attract Chinese advertisers. The partnership could help Facebook wring profits from the Chinese market, even though the social network is blocked by China's national firewall. "There is demand from Chinese advertisers to reach out to U.S. consumers, and this is the way how Facebook can cash in on the Chinese market," says iPinYou CEO Huang Xiaonan.
