More foreign shows may be taken off video sites

Tougher regulations on television series produced in the United States may be coming after four shows, including popular comedy The Big Bang Theory, were removed from major online video sites in line with a government order, analysts warned on Monday.

Chinese video websites should learn how to cope with regulatory changes, although this specific development may have a "very limited impact" on profits, they added.

"The industry is poised to see a longer list of banned TV series because the government's grip on the category is obviously tightening," said Su Jie, who specializes in the online video market for Analysys International.
