Working secretly in his attic, Dr. Kinsey was one of America's original pornographers. His influence inspired Hugh Hefner to launch Playboy Magazine - the "soft" approach to porn - which in time would escalate the widespread use of pornography through magazines, cable TV and the Internet. In 2006 the California Child Molestation and Sexual Abuse Attorneys reported that: "The number of victims of childhood sexual abuse and molestation grows each year. This horrific crime is directly tied to the growth of pornography on the Internet."

The Kinsey Syndrome

Historian Steve Humphries examines failures in policies and legislation put in place to protect youngsters from sexual abuse, and discovers radical new solutions proposed by an increasing number of child-protection experts, which challenge deep-rooted attitudes and emotional reactions to paedophiles. Senior lecturer Sarah Goode believes the most promising way to reduce the number of child-abuse cases is to encourage people to seek treatment before they target victims. Her theory is supported by an interview in this programme in which Humphries meets a man who makes an extraordinary confession on camera.
