One very common example of how the audience participates in the content is in shows that have polling systems , allowing the audience to vote in different circumstances. It allows the audience to have an interactive content where they feel and participate in choosing their favorite contestants, and sustains the idea of objectivity, where the winner is chosen because of who the audience like and not interfering with the subjectivity of the judges, TV network or producer.
One famous show that is now all over Europe is X-factor, it has become very popular and it is a singing contest where ordinary people have the chance of becoming known and also winning the final prize and being signed by a record label. When the live shows start after the other stages the audience who by now have had time in the other stages to form opinions, likes and dislikes and based on that they start voting until the last show where they choose the winner of the contest.
I consider that these types of shows, and especially x factor which is one of the most famous shows, reinforce the idea of having a interactive show where the audience is a direct participant in the show in this way keeping it engaged. Another idea is that audience like forming content because it gives them the sensation of great power when with just one touch you are able to decide somebody’s fate.
