Generation Porn

Gia's 19 and Gianna's 21. They both recently became porn stars in America. In Britain, JT and his son Joe run one of the most successful porn sites in the world.

The second episode of the documentary examines whether pornography is changing people's behaviour, looking at the `gonzo" genre pioneered by John Stagliano's Evil Angel production company. It used to be niche, but today is among the dominant styles of porn. In the offices of Evil Angel, the programme meets photo editor Fallon, who's becoming increasingly disturbed by the extreme images she sees every day. Back in the UK, Rob speaks about how he became addicted to porn, and there are interviews with young men who watch pornography on a daily basis.

This episode visits a high-tech Parisian sex-doll brothel, and meets Cindy Gallop, whose 'real world sex' site combats porn's negative effects, and gardener-turned-pornographer Jason
