Discipline officers will investigate "hidden conditions" in the media, film and television industries, according to the CPC Central Commission for Discipline Inspection on Thursday.

Such "hidden conditions" often refer to bribes offered to officials or directors in order to increase circulation or advertising, or to improve the impact of TV programs or films.

The inspectors will focus on key areas, including the purchase and sales of film and television plays, large-scale programs, equipment procurement or TV satellite coverage," Li Qiufang, director of the central inspection team dispatched to the State Administration of Press, Publication, Radio, Film and Television, said on Thursday.
