Alibaba has made a major purchase in cinemas, marking an important milestone as the Chinese tech giant now controls investments across the entire film industry production chain. According to a filing with the Hong Kong stock exchange submitted on Monday evening, Alibaba will take on a 4.76 percent equity stake in the cinema company. “Cinemas will play an integral part in Alibaba Pictures’ operations as the company aims to build an integrated entertainment platform,” said Alibaba Pictures CEO Zhang Qiang. Alibaba has previously partnered with Hollywood production companies, including Paramount Pictures and Lionsgate to distribute and market U.S. blockbusters, such as Mission: Impossible – Rogue Nation. Alibaba’s first purchase in physical cinemas means the company could soon be overseeing the entire film production process, from investment to production, marketing, ticketing and cinema sales.
