Original content being produced by online video websites is taking away a large chunk of TV's traditional audiences, but as Han Bingbin discovers, much of the creative content is being brought in from overseas.

Chinese video websites' rapid transformation from purely broadcasting platforms to content makers means foreign expertise has been key to fueling their growth. In Sohu's latest hot reality show Secretly Greatly, Chinese stars are placed in weird situations and have their hilarious reactions recorded by hidden cameras. Produced by a South Korean team led by Kang Sung-shin, an influential producer in his country, the show took the industry by surprise.

Since its premiere in April, the 14-episode first season has been viewed more than 100 million times. It's the first Internet-based program to have topped micro blog Sina Weibo's list of most talked-about entertainment shows, eight times.
