By Paul Carsten and Jane Lanhee Lee BEIJING (Reuters) – The website of Chinas biggest Internet video company Youku Tudou Inc was once a haven for illicit Hollywood blockbusters and hit South Korean soap operas, until it realized piracy really doesnt pay. Now the company that controls almost a third of Chinas booming online video market forks out more than a billion yuan ($164 million) a year on licenses so it can legally distribute movies and shows like The Walking Dead, a strategy expected to result in its first ever quarterly net profit. And to protect this market share, Youku Tudou employs a dozen sleuths who scour the web for pirated content, highlighting how Chinas online video industry is courting higher advertising revenues and better relations with foreign media firms by cracking down on illegal content. The biggest challenge is that there are more new ways to pirate video as the technology develops, Lu Changjun, the head of Youku Tudous Internet police squad, told Reuters.
