Shows like “American Idol” and “Pop Idol” satisfy the needs for “self-expresssion”, because competitors will perform their talents on singing, dancing and so forth bravely in the shows. Shows like “Survivors” are perfect satisfaction of discovering people’s “true potential”. Audiences can easily find competitors’ “true potential” and enjoy the fighting between the competitors.
