I don't watch them but there are two shows about that:
*Star Academy, since 2001, the seventh season will start in september, 16 contestants are locked in a castle during 16 weeks, there is a daily show + a big 3 hours show on friday night. 3 people are nominated by the teachers, 1 is saved by the public vote on friday, and, that's a great twist I think, the other contestants evict one of the 2 remain nominees, that's evil ! The last 7 contestans make the big "Star Academy tour" all around the france during 3 months. The winner has a €1.000.000 contract with a big label.
*Nouvelle Star: the english version of Pop Idol. The 5th season is on air, and it's a huge success. By the way, this year is the most controversal ever because all the evicted singers are black. For the press, it's a racial discrimination.
The 2 shows are really different because, since french Big Brother has been axed, Star Academy became the "Big Brother" but with music in it. We watch their every moves, their arguments, their romances. But with Nouvelle Star, there is only one show per week, and we don't watch their life, only the performances. It's better because we see only the talent and not their "behaviours outside".
But I watch any of them, it's rubbish !
The only real-tv show that I watch is Big Brother all around the world, that's it !
