From Danwei: "But conspicuously missing from the list are the Big Three of the Chinese Youtube clones: Youku.com, Tudou.com and 56.com. Although 56.com has been off line for nearly two weeks after an apparent porblem with the authorities, these three websites have the largest amount of funding of any video websites in China, most of it foreign. By most accounts they are also the most popular video sites in China."
