The British government has launched a review of regulations governing children's appearances on reality TV programs, the London Independent reported today (Tuesday). Ed Balls, secretary of state for children, schools and families, told the newspaper that several program producers appear to be using children "to keep pushing the boundaries of what is acceptable to provide shock value for viewers and push up ratings." He particularly cited one program, Boys and Girls Alone , in which 20 children were left without supervision to create their own community, with several of them ending up fighting and crying. He also singled out another reality show, Wife Swap, in which parents swap families.
