TV viewers want the 9pm watershed kept - and also want satellite channels to sign up to it, a report suggests.
Parents wanted to protect their children from sex on TV, the report said
The Independent Television Commission's (ITC) report The Watershed found 95% of adults and 77% of children polled thought there should be a watershed.
Nearly 80% of adults said the watershed should apply to satellite channels as well as terrestrial.
Many parents and carers said they used the 9pm watershed as a way of controlling their children's viewing.
The ITC's findings came after a survey panel of 109 participants, and follow-up panels that questioned 4,000 adults and 1,500 children over viewing habits over the course of the evening.
The report said most people were aware the watershed was a 9pm point, after which programmes were increasingly less suitable for children.
The survey discovered participants found three purposes for a watershed. These were "protection of children, provision of a safe viewing zone and restraint upon broadcasters".
Violence and sex
The report also found that children aged under 12 had their television watching controlled much more than teenagers, with children aged between eight and 12 deemed to be the most impressionable.
Parents were most likely to stop their children from watching certain programmes because of violence, sex or bad language.
Children under eight were thought to be less at risk, because they were in bed by 7.30pm and a were less able to understand a lot of the adult or offensive material if they were watching.
The survey's respondents said they would want no swearing or violence - especially acts which could be copied by children - between 6.30 and 7.30pm.
