The current trend in finding talent bu television channels have become rude . This i think was started by American idol . In India Sony's Indian idol copied it . The zee TV which was famous for finding singing talents also chose format which is being rude to contestants. Only difference in zee the judges fight a lot . Now Star's show is trying the same .
But i think the rudest show is MTv's roadies and Gordon Ramsay's Hell's Kitchen .
