Alibaba Group and Yunfeng Capital, the venture capital firm co-founded by Alibaba founder Jack Ma, have bought USD1.22 billion worth of shares in Chinese online video service Youku-Tudou. Alibaba thus has had 16.5% stake in one of the largest online video platforms and Yunfeng holds 2%. LeTV has become a well-known smart TV brand that hopefully will convert its online video users to smart device consumers, or vice versa. iQiyi has introduced investment from Chinese search giant Baidu who has been channeling search traffic to it. Online video platform is one of the few Internet service categories Alibaba Group hasn’t tapped into.
