Thousands of unauthorized foreign TV series have been taken off video websites as the authorities pay more attention to copyright issues. Youku signed agreements with three major South Korean TV stations — MBC, KBS and SBS — for authorized screening of TV series, but made little progress on cooperation with American TV producers due to “higher royalty payments and strict content censorship (in China)”, according to a video website executive. Tudou is attempting to fill the gap by producing its own films and TV series. “Welcome Love to Visit” is the portal’s first Web drama, made at a cost of CNY6 million. “From website operators to video producers, content copyright has become more crucial to the survival of video portals,” said Li Shanyou, CEO of the video website Ku6.
