I am not particularly keen on watching TV, as in my opinion, not many TV programmes are worth watching but unfortunately the good ones end very late at night. As I often have to get up very early I prefer not to watch those films which finish very late, however good they may be.

"Operaciosn Triunfo" and "Mira quien baila" are some of the programmes that I usually watch. They both have something in common: they are both about acquiring artistic skills through effort and hard work. The difference between these programmes is the way they end. In the first programme the winners donate the prize money to a ngo. In the second programme the winners are offered a recording contract.

In conclusion, these programmes are family orientated. The presenters and contestants in both programmes are friendly and funny, so enjoyment is guaranteed. I really enjoy watching the dancing and listening to the songs.
