The correct answer to this open question is the following.
Indeed, televised talent shows have become popular in many societies today. These shows serve both purposes: they are good methods of finding talented people, and they are very entertained.
However, we must say the following. In general terms. these TV shows are big businesses that are sponsored by large companies and produced millions of dollars in advertisements. They serve as light entertainment and they compete to get a larger audience.
Very talented people indeed compete to get an opportunity to become the next "bright star" in the show business industry. But just a few people are really supported to start a career in mass media or to sign a lucrative record deal.
