The broadcasting watchdog Ofcom is proposing new safeguarding rules for reality or unscripted television and radio shows. It says that “due care must be taken over the welfare, well-being and dignity of participants in programmes." In addition, “participants must not be caused unjustified distress or anxiety by taking part in programmes or by the broadcast of those programmes."Ofcom is currently inviting feedback on these proposals - but what counts as "unjustified distress and anxiety"? After the deaths of three reality show participants, is an overhaul of safeguarding long overdue? Or might tighter rules drive up costs, drive production overseas or block vulnerable people from getting the media platform they want - perhaps to combat stigma or highlight an important issue? And don't we enjoy watching members of the public rise to stressful challenges?
