According to the regulation released by China's media watchdog, the State Administration of Press, Publication, Radio, Film and Television last September, video streaming sites must get publication licenses for imported films and TV series if they want to broadcast.

The administration also asked streaming sites to register all foreign films and TV series they are running or plan to run to media administrative departments by March 31.

As a result, it will be difficult for streaming sites to air newly produced American TV series in China as they are released in the United States. Audiences will only be able to watch the show after the whole season has been released and passed review.

Sohu did not return phone calls Thursday seeking comment.

Younger Chinese audiences often complain Chinese TV programs are dull, resulting in more and more turning to foreign TV.

The first season of "Prison Break" garnered a weekly hit of 2.1 million, ranking third among Sohu's foreign TV shows. The first season of "Heroes" also ranked high on Youku.
