They use sentimental archetypes that manipulate viewers. Teenage soap operas make stereotypes of common teen profiles to attract them.

Teenagers are very special persons.
They have a lot of emotions and feelings and they don't like a monotonous life. They like exciting lives. Now, powerful media like gossip magazines talk about famous people because they pay the famous a lot of money to gossip about their lives. Another example is publicity. The psychologists from advertising companies use feelings and emotions to convince people to buy products.
