Have television shows that British children watch become too violent over the past decade? The British broadcasting regulator OFCOM said on Monday that it will commission a study to find out. It noted that there has been a lack of detailed studies during the past year about the level of violence on programs that are televised before 9:00 p.m. the so-called watershed hours when children are likely to be watching. The protection of under-18s from potentially harmful content is a key area of concern for OFCOM, said Tony Close, the regulator's director of content and standards. At the same time, OFCOM ruled that the Channel 4 soap opera Hollyoaks broke broadcasting rules when it aired scenes of a violent death on March 19. It noted that 15.7 percent of the audience for that program was 4-15 years old and 10 percent was 4-9 years old.
